10 Stopper Comparison, Heliopan vs Hitech

With the recent purchase of a 2nd ten stop filter I finally had a chance to compare 2 of the them side by side. My original filter, a Heliopan ND3.0 has been well used and was a very good buy. However, the screw in can be cumbersome especially if you recompose for any reason.

The big problem with a screw in 10 stopper is that with it in place you can’t see anything at all through the viewfinder. This means you need to remove the filter to recompose and attach again for the shot. Either that or guess the composition, ramp up the ISO, take a test shot of a few seconds and adjust till you get the composition and then drop down to a low ISO and take the shot. Neither that handy if I’m honest.

Hence, the attraction of a slot in 10 stopper. In a perfect world I’d have bought a Lee Big Stopper, a proven product. Sadly, the Lee filter is almost impossible to get hold of right now thanks to supply issues at Lee and 2nd hand items are going for nearly double the price on ebay. Facing either nearly £200 for a Lee or a 6 month wait I opted for the new Hitech Pro Stopper.

Hitech claim this filter is made of a new IR resistant resin and they also claim to have fixed the light leak issues of the old filter by adding a 1.5mm gasket (for Lee holders, 3mm for Hitech holders). The filter comes in it’s own pouch and does seem pretty well made. Price is reasonable at £72 from TeamworkPhoto. TeamworkPhoto also supplied by Heliopan at a cost of £92 for the 77mm version.

So, how do they compare side by side?

10 stopper compare

This was a shot taken one after the other in dull conditions. Both shots were 90s exposures with a Hitech 150 0.9 GND in front of the 10 stopper. Same ISO, same lens, same f setting etc etc. The shot is a straight conversion of the RAW file to jpg for each with no PP applied.

As you can see, the Hitech does have a pronounced blue cast compared to the Heliopan which has a slightly warm cast but much better colour reproduction. Casts are not that hard to remove but obviously there is a lot less work to do with the Heliopan. The blue cast however, might be desirable in seascape type shots.

The Hitech also seems to let in slightly more light that the Heliopan, maybe not quite a full 10 stops? Other than that, all other areas of performance seem fairly equal.

So, it comes down a choice between the convenience of the slot in filter vs the colour reproduction of the screw in filter. Shooting for B&W, the slot in will be fine. Shooting for colour, I’d go with the fiddly screw in every time.

I’m going to keep the Hitech filter though, it’s got a place to be used where the screw in maybe isn’t convenient. The Hitech too unlike the other popular 10 stoppers in the market isn’t glass, it’s resin which should make it far less likely to end up in a million bits on some slippy rocks somewhere!

The never ending quest for decent photographic filters

About a year ago I made my first serious move into using filters in my photography. At that point the furthest I had gone down that route was a few cheap screw in circular polarisers, ND8’s and UV filters, which were fine for what they were but the more I read about filters and seen what other people were doing with them the more I wanted to stick a toe in this whole new world of photography.

Cost was an issue, isn’t it always, so I lowered expectations and bypassed the pro systems like Lee or Cokin Z and stated to look at a P series system, the 85mm slot in filter range. This seemed perfect as the filters were reasonably priced and there was a huge range to choose from. After some initial research I discounted Cokin’s range of ND filters as they got a terrible feedback online with dozens of complaints of purple colour casts on shots taken with the Cokin ND’s.

Eventually I settled on Formatt Filters Hitech range which seemed to be a decent alternative and bought a set of 0.3. 0.6 and 0.9 ND filters and a set of 0.3, 0.6 and 0.9 ND soft grad filters. Throw in a P series holder and a 77mm and 67mm adapter ring and I was no more than £75 out of pocket for a basic setup. I quickly also added a Kood 85mm slot in circular polariser to this line-up and for just under £100 I was ready to go.

The journey though, was a rough one. I learned a lot about filters and found that Hitech filters did indeed colour cast, especially with more than 2 stacked together. A 0.9 on its own was fine. A 0.9 soft grad on its own was fine. Stack the 2 and purple skies all round. At this point I nearly gave up, disheartened by the new purchases as they seemed to be a step back rather than the step forward I had hoped for.

In this situation, rather than throw in the towel it’s better to try and understand what is actually happening and how you can best avoid it. To this ends I started to see which conditions the filters worked best in and also figured out how to remove the worst of the cast in Photoshop so it was less of an issue. I soon stated using them all the time and was getting some reasonable results.

By this time I had added a cheap sunset grad, Kood red soft grad, Kood light tobacco soft grad and a Cokin 81A warm up filter to the collection and found that each of them worked best in certain situations. It took a lot of trial and error but once the understanding was there it made the frustration a lot less. Once you understand that in the middle of the day a red grad will give a shocking false image and used on a sunset it will work nicely you can really move on!

The next step was delving into long exposure photography. Initially I done this by stacking a screw in ND8, first then attaching the p series holder fitted with the Hitech 0.9 ND, 0.9 ND soft grad and 0.6 ND soft grad. Colour casting was horrific but I was able to get exposures up to long enough to streak clouds and flat out water, although the shots could only be used as mono conversions.

The solution to this was to invest in a proper 10 stop filter. Some research suggested that screw in types were best as they avoided light leak so I attempted to get a B+W ND110, which was the first time I came up against the difficulty in getting good filters. These were nowhere to be found, most places were quoting 6-12 week lead times which were no good to me, I wanted it now! Another quick Google and it seemed that the Heliopan ND3.0 was as good as the B+W and luckily, there was a stack of new 77mm versions on EBay at £95 a go. Cheaper than the B+W but even better, available now.

The Heliopan changed everything. Long exposures with no cast were now possible. Even stacking one 0.9 grad in some situations was possible but it still gave horrible casts from time to time. Not the Heliopan, it was perfect but the Hitech was no doubt the cause of the problem.

This got so frustrating I ended up buying the Lee filters foundation kit with intent to move to Lee filters, no matter what the cost. I got the holder at a decent price and it lay there unused as I had no 100mm filters for weeks on end. The problem this time was the lack of Lee filters anywhere. There are just none for sale, or at least for delivery this side of Christmas it seems. Some places are quoting 16 week + lead times for any Lee resin filters and as a result of this the 2nd hand market for them is nuts. 2nd hand Lee grads are going for silly money with this shortage and the “Big Stopper” even worse!

Eventually out of frustration I looked again at Hitech filters. Some recent blog comment seemed to suggest that the company had a new resin it was using and the results were near comparable with Lee filters for a fraction of the cost. This was based mainly around the Hitech equivalent to the Lee Big Stopper but there was also a new range of 100x150mm Hitech filters.

A quick search on eBay shows these filters going for around £40-£55 but in one of these rare moments where you get an actual bargain on eBay I found individual 0.6 and 0.9 soft grads for sale, made an offer and now own both for less than the cost of a single filter from some of the other sellers, both brand new and unmarked!

A quick test with these in conditions I would have normally expected to see colour cast produced no colour cast at all. Even a 30s exposure in tandem with the Heliopan 10 stopper produced no cast which is an encouraging start. Over the course of the next few weeks I’ll try these in a variety of ways and conditions and report back what the overall impression is.

If it’s good then an investment in a Hitech 0.9 reverse grad may well be in order and I’ll have to possibly consider the new version Hitech ND3.0 as well. The screw in Heliopan is a terrific filter but screw in and out in cumbersome if you need to recompose. A slot in option might well be handy but only if it performs as well.

I’m not discounting a switch to Lee in the future but for now while there is no availability there’s nothing to lose in trying the Hitechs, if nothing else it’s letting me use that nice new Lee filter holder at last!


Photography and planning around nature

In the time I’ve been seriously taking photographs, one thing I’ve discovered is that a little research pays dividends before you travel to a location to photograph it. I used to just turn up where I fancied and snap away, now with a bit more experience under the belt I usually have some idea of what kind of shot I want before I get there and it’s pointless going if the conditions aren’t going to be right!

Here’s a perfect example, this is the Belhaven Bridge just to the east of Dunbar:
Belhaven Bridge
At this location, high tide covers the walkway to the bridge so the bridge looks as if it goes nowhere with deep water either side, it in fact, spans the Beil water as it exits into the sea at this point which you can see at low tide. So, using the Tide Times website, I knew when high tide would be so headed down there for that. Sadly, it didn’t co-incide with sunset which you could check out on Suncalc.

Arriving later than hoped the tide was peaking but not covering the walkway. I know from research that night at the high tide height was 4.6m so; it follows logic that the walkway was just on the verge of being covered so waiting for a day with a tide predicted to be higher than 5m will give me the shot I want. The perfect time to take this shot will be a high tide, 5m+ co-inciding approx 20 either side of sunset. High tide and sunset co-incide on 24th May but with a predicted tide of only 4.2m it’s not the perfect night to get the shot, better to wait a couple of weeks and try again.

Tides also play an important part of decisions where harbours are concerned. I love long exposure shots but high tide, long exposures and boats bobbing about don’t go! Nobody wants blurred boats! In this instance, it’s better to forgo the 10 stopper and use a faster shutter and wait for a lower tide, or at least the boats in the front of the shot to be grounded. Of course, you always have the option of cutting the boats out of the shot altogether, but unless there’s something else as a good focal point then this leaves you with limited options.

This is Newhaven Harbour at high tide, boats left out of the shot:
Easter Monday Sunset

And at low tide, with boats!
Harbour Streaks
Both shots long exposure but with very different results.

Clouds are another feature of nature to keep and eye on. Nice blue skies are all very well, and indeed welcome in some cases but a bit of cloud cover always helps. To try and give an example, this is the top of the Falkirk Wheel on a day with little or no cloud cover:
On Top of the Falkirk Wheel

and a few weeks later on a bright day with loads of clouds of giving nice contrasts in the sky:
Falkirk Wheel up top

I know which shot I prefer…

Fast moving clouds, by which I mean heavy broken cloud, are great for long exposure photography. Huge dark clouds with little or no definition are not! Clouds can also add a lot to sunsets as the light bounces off them and in HDR photography you can create dramatic scenes with a nice cloud cover:
Storm Clouds over Edinburgh

So, before you head off. Keep an eye on the:

Weather
Cloud cover
Tide times
Tide Height
Sunset/Sunrise time
Sunset/Sunrise position

And plan accordingly!


So you want to upgrade to a digital SLR?

You’ve had your compact camera for ages now and while you like the convenience you’re thinking of making a step up to a DSLR aren’t you? It’s hardy surprising, 10 years ago a DSLR was very much a luxury item, you could by a car for less than most around at the time, these days with entry level DSLR’s wit kit lenses coming in at under £400 for everything you need to get started it’s becoming a more and more tempting proposition for many.

But… before you rush off to your local camera dealers, or start furiously researching best prices online, ask yourself, what do you actually want from your camera? Do you just want to take pics of your mates drunk in the pub or just a few snapshots of the kids? Then, save yourself some cash and stick with your compact, it’s more than suited to the tasks in hand. On the other hand, if you find yourself getting a real interest in photography, feeling the urge to try and take better pictures and find you use your camera a lot then go right ahead, you won’t be disappointed.

Actually, that last statement is a lie; you will be horribly disappointed and equally frustrated when you move up to a DSLR. Just because you have a “proper” camera, it won’t make you a photographer overnight. There will be a lot of learning ahead, trial and tribulations and probably tantrums and tears as you get to grips with your new toy but rest assured, its worth it all as eventually you’ll get the results you want if you persevere.

What you have to remember is, this is a proper photographic tool you’re investing in. Even a cheap one will blow most compact cameras out of the water but you have to change your way of thinking. Don’t use it like a compact; don’t stick it on auto and snap away, what’s the point of that? Your compact can do that! What I’m going to detail isn’t how to use your camera but the things you should stick at to learn how it works properly. What to focus on to help you get the most from your new camera.

First things first, what equipment do you “really” need?

Ok, so obviously, you’re digital SLR. Be in Canon, Nikon or any other makes, it might seem unimportant but think on before you buy. That Pentax might be a great deal as you eye it up in Jessop’s, but think further down the line. Is there a good supply of lenses for it? How do the prices look? It’s important as typically once you buy into one system and start to add more lenses you won’t want to switch to another. I bought into the Nikon system and have since added 9 lens to my collection, to switch to Canon and re-buy all these lens’s would be horribly expensive so choose wisely. My honest opinion, go Nikon or Canon, a safe bet all round. Try both in the shop; see what you prefer as both will be very capable performers.

DO; buy the camera with the kit lens. It’ll be cheaper than buying the body only and adding a lens to that. Most kit lens will be in the 18-55mm range which is fine for a wide range of applications and it’s enough to get you going. The camera shop will invariably try to see you a UV filter to go with your new toy. No harm in that, it’s good for protecting your lens and does cut down haze but… think about it first. If the shop is trying to sell you a branded UV filter you may be paying upwards of £30 for it. They’ll sell it mainly as lens protection and there’s no doubt that it will protect your lens front element, however which in a camera bag etc, your lens cap will also do that and while it’s in your hands, the chances of scratching the lens is minimal. I have no UV filters anymore, I had 9 scratch free lens’s and believe me I am the worst in the world for chucking them back in the bag minus lens caps. Don’t waste your money on a UV, just treat your lens with respect, look after it and if you have the cash invest in a polarising filter instead.

Used properly, a circular polariser will enhance the blues in sky, make the contrast to clouds better and cut out glare from water, shiny surfaces etc. A million times more useful than a UV. More expensive sure, but look about online, you’ll get unbranded ones that while certainly not as good as your Hoya’s etc it’ll be more than adequate for starting out and you’ll get more proper benefit from it than you will a UV.

Also invest in a tripod of sorts, how much you spend is up to you. Tripods can range from a few pounds for small spindly effort to hundreds of pounds for the all signing and dancing carbon fibre models. Go mid range, even going to about £50 will pay dividends in the end. You’ll almost certainly upgrade it if you really get into this stuff no matter what you buy. While you at it, get onto eBay and get a remote control too. Needn’t be one of the mega bucks ones, a simple IR or corded remote for a few pounds is adequate.

Finally, a bag. You’ve got minimal kit so a small bag will do right? Well, depends if you’re going to add more as you go along? Eventually, that small bag will be overflowing and you’ll need another one. I bought a Loewpro mini trekker many years ago. £60 seemed a fortune for a bag but it’s still going strong although bursting at the seams now. You get what you pay for here!

So now you’ve got your kit, what first? Well, forget auto mode. Stick the camera on Av, aperture priority mode and leave it there. Learn about depth of field, how to focus, the difference of aperture vs. focal distance etc and you’ll get a pretty good grounding. Aperture is all in photography. Take a pic of something close to you, say 2ft away at f3.5 which your lens will probably do, then take the same pic at f22. Look at what you have and you’re on the way to understanding the cornerstone of photography.

Do; use your tripod and remote switch often. Not just in low light, if you photographing landscapes get into the way of using it, even in good light with fast shutter speeds. I originally shied away from the tripod, feeling a touch self conscious using it out in public, now I rarely take a shot handheld.

Now, this next statement will have some photographers out there crying in disbelief… and this is all the more important if you’re photographing landscape, cityscapes etc… LEARN ABOUT HDR PHOTOGRAPHY. For a few quid you can buy Photomatix Pro software and you’re on your way. HDR, which spat upon by most advanced or pro photographers is a post processing technique where you combine 3 exposures, one normal, one overexposed and one underexposed to get an final composite image with an increased tonal range. In shot, it can make an average picture look stunning, especially to a beginner. Read all about it and learn how to do it. Why? Because if you do, you will be amazed at the results, so will your friends and family and that encouragement will drive you on. I love HDR; it gave me a real boost while I was learning. It let me do things my camera and kit were not capable of doing in a single shot and these results spurred me onto more. I rarely do HDR anymore as I’ve increased my understanding of filters etc but in the short term it will give you great incentive to take more and to experiment and that can’t be a bad thing can it?

Sign up to Flickr or Blipfoto. Get involved in the communities, you’ll find plenty people willing to offer advice or even some tuition to help you along. Remember to not make it all one way traffic though, the more you put into these the more you get out. Upload regularly, learn and be inspired by others and you’ll be surprised how quickly you come on.

This will all keep you gripped for months but eventually you’ll want to add more kit. It happens to us all; maybe even upgrade your DSLR? You could spend forever but spend wisely. Think about what you’re getting, what you’ll use it for and most importantly spend as much as you can afford. Cheap lenses especially are rarely good lenses.

Initially for lens purposes think about adding a 50mm f1.8 first. This is a prime lens, i.e. no zoom, it has a large maximum aperture of f1.8 to allow some great depth of field shots and most importantly, they are cheap in lens terms, around the £100 mark. Every photographer should own one.

After this look for a decent zoom, something up to around 200mm. There are a load of cheap lenses out there up to 300mm but believe me, image quality at 300mm is crap, don’t be swayed by it. I bought a Sigma 70-200mm f2.8 EX HSM, expensive yes at over £600 but I’ve never needed another big zoom since, it’s so good it does it all!

These 3 will be more than enough for most but you may also get the urge to add a wider lens at some point, a valuable addition to any landscape photographer’s camera bag. True macro Len’s are also popular, by true macro I mean 1:1 reproduction. Don’t be fooled by lens’s which have 1:2 or 1:3, these are general purpose lenses with a macro function, NOT a true macro lens. There is a massive difference, believe me.

You might also notice the huge array of filters available. I would recommend getting yourself a P series holder and some 85mm filters, starting with a set of ND and ND soft grad filters. These will fit any lens regardless of size as long as you get the adapter ring for each lens. Much more convenient that the screw in systems.

Above all, have fun with it. It won’t all be easy going, you’ll get days you look at what you took and delete the lot but stick with it, you get it in the end and every now and again you’ll get an image that actually excites you then you’ll understand why you do it!


Photographing Edinburgh’s April Sunsets

What a week it’s been for the old sunset shots! It also helps that sunset is at a hospitable time at the moment too. Setting around 8.40 is much preferable to being out and about at the back of 10 or worse still, being sat in work watching the sun give a great visual display on the horizon!

My last post gave you whole tale of how I managed to get my favourite sunset shot of the year so far, but as I can see from my Flickr photostream, April tends to be a particularly good month for sunset shots around Edinburgh for some reason.

This was last night’s effort. The original plan had been to head down to the Cramond Island causeway, but since I’ve done that to death I headed down to West Shore Road instead to a spot further along the coast I spotted the other night which had a perfect view of the causeway, Cramond Island and the Forth Bridges behind.

To say this was a difficult shot to take would be an understatement. The sun was still high in the sky, actually just above the top of the shot. With the distance I switched to the Sigma 70-200mm f2.8 EX HSM for a bit of extra reach but actually expected it to give me horrible lens flares, which surprisingly, it didn’t. Once again, I framed up the shot with no filters, locked up the tripod and slipped on the now invaluable Heliopan ND3.0 10 stopper, the result was a pleasing enough shot with a nice gentle orange glow in the sky but it left the water a touch dull.

To combat this I slipped on the adapter ring and filter holder and slipped in the sunset filter. With this in place I could stretch the exposure out to a full 60s, after a couple of goes at setting the grad this was the final result. It took a fair bit of post process if I’m honest as shooting into the sun had brought out every single dust mark on the sunset filter, of which there were many! There was also a bit of flare I’m managed to just about eridacate with a little dodge and burn. If I were to try this again I think I’d try shading the filters to try and get rid of the flare from the shot in the first place.

Silverknowes Sunset

The night before though also produced a surprise shot for me. With the position of the sun and ideally wanting to get it over water the Western Harbour at the back of Ocean Terminal is a great spot. The obvious shot is the old pier with the Gormley statue at the end of it, but the flats at the other side of the harbour make for a good shot too, especially if the water is still.

However, it was the pier that produced the goods. I’ve shot this before on long exposure and had a lot of issues with light bouncing back into the lens from the filters and I finally figured out why. At this location there is a shiny bare metal fence which I sit the tripod up against to get the shot, the light has been bouncing off the metal and back up into the bottom of the filters and I effectively get a reflection of the inside of the lens on the shot, just putting an arm along the fence was enough to get rid of this totally, amazing what you can figure out.

Again with this shot, I set up the shot without the 10 stopper in place, played with the filters to see which combination worked best and then screwed in the ND3.0 and slipped the other filters back on top. In this case, I’ve used the ND3.0, circular polariser, ND0.9 soft grad and sunset grad filter on a 3 minute exposure to get the colour and effect on the water. The sun was still in the sky off up to the left of this shot.

Happy with a sunset photo at last…

It’s not often I drop a new blog post about a single shot but I liked this one so much I thought it worthy of a little write up.

As you will see if you follow back my recent posts I’ve been experimenting with long exposure photography over the last few weeks, in fact, it’s becoming more of an obsession than an experiment.

What I have had bother with though, is getting decent colour into shots, hence why my Flickr Photostream has gone rather monotone of late. Stacking those Hitech ND soft grads is just a sure-fire route to a purple colour cast on the D90, which is pretty undesirable to say the least. However, last night everything just fell nicely into place and I ended up with, what has to be, may favourite shot of the year so far.

The original plan had been to catch the sunset at Longniddry over the rocks but other things I had to do put paid to that and I would have only made Longniddry just before the sun went down which would have been ok if I was more familiar with the location. As I’m not I diverted back up the Edinburgh coast with the intent to catch the sunset over the Western Harbour. However, since the shows are at Ocean Terminal just now and the place was overran with walking JD sports adverts with attitudes I headed for the more peaceful refuge of Newhaven Harbour instead.

I really didn’t want to be at Newhaven having really photographed the place to death over the last few weeks. Its easy location and multiple shot possibilities make it and attractive location but it’s fast becoming my new Colton Hill, somewhere I’ve visited so often I get bored of it.

With the sun setting though, it was Newhaven or nothing and apart from anything else, at this time of year bar the Forth Bridges, it’s probably the best sunset location in Edinburgh. Sunset was still about 25 minutes away when I got there so I originally setup with the Sigma 10-20mm on the D90 and took a few tester shots using the grads and polariser but no 10 stopper. 10 stoppers are only any good in harbours if the tide is out, with it in boats tend to bob about and blurred boats do not good pictures make.

With the sun and the available light dropping fast I moved position to put the sun behind the lighthouse to avoid any lens flares and replaced the ultra wide with the Sigma 70-200mm f2.8 EX HSM, my absolute favourite lens. This let me frame the lighthouse and harbour wall nicely but avoid any boats in the shot. I then added the 77m filter ring and slipped in the polariser, ND 0.9 soft grad and tried a few test shots. I also experimented with a light tobacco grad and sunset filter but it was the red grad, a filter I’ve never used as I hated the results that was producing the goods. With the grads set properly, I locked the tripod securely and removed the filter holder and put it down on the camera bag careful making sure the grads didn’t move. I removed the 77mm ring and fitted the Heliopan 77mm ND3.0 10 stopper, fitted the 77mm ring to that and carefully slotted in the holder with the grads. I had to do it this was as with the 10 stopper fitted there was no way to line up the red grad on the horizon as you can’t see anything.

With light fading fast I upped the ISO to 200 and opened the aperture up to f8 and went for a 2 minute exposure which was ok but the red was too intense. I tried again upping the exposure to 3 minutes which turned out perfect.

As far as post process work went, there wasn’t a lot to do, the pleasures of getting it more or less right in camera. I created a new adjustment layer and increased the exposure to lighten the inside harbour walls and bring out some detail. I then erased all but the harbour walls from the layer. I then added a new photo filter layer to intensify the colour in the water, other than that, that’s about all I had to do with this one. Thankfully the sensor clean I attempted the day before must have been spot on as there was nothing needed cloned out at all. A welcome surprise.

So here it is the final product and most certainly my favourite shot of the year, so far…

Easter Monday Sunset


The Long Exposure Learning Curve Continues…

If you follow this blog you’ll know I’ve recent found myself caught in the grip of long exposure photography. Something I’ve done in the past with mixed results, but with methodical use of my range of filters I’ve discovered a lot this past couple of weeks. I still feel I’m being constrained slightly by the equipment but learning a lot and getting some images I’m very happy with as a result.

Keep the filters clean!
This was a lesson learned the hard way. I’d never cleaned any of my slot-in filters since I got them back in September. Screw in’s for some reason Iim happy to wipe down with whatever’s at hand, but I’ve been overly precious about the slot in filters. Which became very evident after a trip out and then finding I had to clone out dozens of marks on the shots. All very well but sometimes it’s not that easy to get a smooth clone on streaky clouds etc, so best avoided.

To clean then I’ve been washing them gently under a warm tap, dabbing dry with kitchen roll and then finally cleaning carefully with a lint free cloth. Seems to work fine. You can see marks on all the filters but these don’t show up at all on the images, huge difference.

Be aware of the where sun is!
This is another one I’ve finally figured out. Some shots looked dreadful. Such a disappointment when you see the camera preview, get home and find all sorts of strange flares and marks all over the shot.

What I’ve found is that with the sun directly behind you it seems to hit the filters and bounce light back into the lens and highlights any marks on the filters. With the sun to the side and rear in some cases it causes the camera to actually record the front element of the lens on the shot as a reflection. Funnily enough, shooting near on into the sun, if you can avoid the flares seems to work fine? To this ends though I’ve taken to trying to shield the filters in some way from stray sunlight, fortunately, living in Scotland, it’s not that big an issue!

Wind is both your friend and enemy
After a night out with the camera on Friday it brought home just how good and how big a pain in the rear end wind can be. On the plus side, high winds ripple water nicely making those smooth milky sea shots a lot easier and it sends the clouds racing across your shot, also desirable. However… it also blows your tripod about all over the place, even a sturdy one. It’s worse still with a stack of rectangle filters in front of the lens giving it more to catch onto. I’ve seem me this week almost standing over the tripod trying to shield the camera from the wind. Nothing worse than a 3 minute exposure and you see the camera move just as you get near the end.

All these shots were taken in near gale force winds:

Newhaven Lighthouse Long Exposure

Old Pier in the Western Harbour, the wind was especially bad here:

In bright conditions, lose a grad and use the polariser!
My P series filter kit gives me the option of using 3 filters in front of the lens and my screw in ND8, typically for these long exposure shots that means a Hitech ND0.9 soft grad and 0.6 soft grad. However, as I’ve discussed in previous posts, the ND0.9 causes a horrific purple colour cast.

What I found on Saturday though, was that in bright conditions with blue sky around, to replace the ND0.9 with the circular polariser and keep the 2 grads, still lets me push around 20-30s exposure in very bright conditions and keep some colour in the shot too as there is little or no cast. The polariser has the added benefit of darkening the sky and highlighting the clouds, even losing the 0.6ND and using the 0.9ND for B&W work with the polariser in place was very beneficial. So, use the polariser and experiment with your other filters in bright conditions.

All these shots were taken with the polariser in place:

Despite the best efforts of some strange foreign bloke to get in every shot, these were taken in Portobello beach with the polariser slotted in place instead of the ND0.6 soft grad.

Experiment!
I cannot recommend this enough; try different things you never know what you’ll get. This shot on Calton Hill was taken with the ND0.6 soft grad, ND0.9 soft grad and a sunset filter in place, not a particularly long exposure at 40s but I liked the resulting colours.

Finally, I’ll leave you with a couple of other long exposure mono shots from last nights trip to Cramond just as the tide was on its way out.

Above all though, I’m enjoying this learning curve a lot. I’ve already priced up how much a move to the Lee pro filter systems will be. At approx £550 for what I want, the saving starts now!


Long Exposure learning curve

Up until last September I was quite happy to grab the camera, a lens, usually with a polariser attached and go for a wander, snapping whatever took my fancy and then usually converting it to HDR. Then something happened… I discovered proper filters.

Now, I’d used filters, or more correctly, briefly filtered with some cheap screw in filters but to no great length, I had no real need as I was quite happy with what I was doing and the results I was getting. Then I started to take notice of some stuff on Flickr, those cream water seascapes and the likes and something kindled a new interest.

After some research, I decided not to go down the Lee filters route, yes, I know how good they are but being realistic, there was no way I could commit to the Lee system with the cost of the filters. I’m not a pro therefore didn’t feel I could justify the huge expense of these; it has to be said, very good filters.

Cokin was rejected after reading some horror stories about colour casts so I eventually bought myself a set of 0.3, 0.6 and 0.9 Hitech ND’s and a set of 0.3, 0.6 and 0.9 Hitch soft grads. Throw in a 67mm and 77mm adapter ring, holder, wide angle holder and a Kood slot in circular polariser and I was ready to experiment. Since then I’ve also added a Kood light tobacco grad, Kood red grad, Cokin 81A warm up filer and a cheapy ebay sunset filter. All in cost, less then the cost of 1 Lee filter. Nothing likes the quality but good enough for me to play around with on my D90.

First impression was this was going to be a huge learning curve. I got the dreaded colour casts while using the ND0.9 and ND0.9 soft grad and to be honest, I was ready to give up once I see that. BUT, I kept using them, mainly just a single grad and polariser and got some reasonable results. Steadily the grads especially became 2nd nature to use but something was missing, I wanted the flat sea and streaky cloud shots and these filters were just to giving me that.

Then, by chance I found an old ND8 screw in filter I had forgotten about, which being double threaded let me put the 77mm adapter ring on top of that, with the filter holder attached to the adapter ring, and the ND0.9, ND0.9 grad, ND0.6 grad in the holder I was able to push exposure times to 3 minutes and more in daylight, finally, the result I wanted without the expense of buying a B+W ND110 10 stop filter.

To be honest, it only works in B&W as the colour casts are horrible, but until I can get my hands on one of those B+W ND110’s then this do just fine for me. Very happy with the results.

Still got a lot of learning to do, I wish I had stacked 2 grads taking this shot but at least it gives me an excuse to go back and try again. Amazing what you can do with what you find lying about in the pits of the camera bag!
