Duxy’s Underwater Photography Blog: Available Light, Part 4
This is the final part in our series on shooting in available light. Part one was all about shooting with wide angle lenses; part two covered Custom White Balance; and part 3 was about the pitfalls and problems of shooting with Custom White Balance.
For the fourth and final instalment I am going to cover all of the extra bits and little things that don’t fall into the earlier sections.
So we are going to look at colour correction using filters and also colour correcting after the fact when you are shooting on a camera that produces RAW files.
Processing wreck shots, and whether or not to go black and white.
And is it possible to shoot available light macro?
Correction Filters and the Underwater Mode
Some cameras don’t have quick and easy to use Custom White Balance controls, which can put folks off. And they often want a one stop solution.
In days of yore, (and tbh sometimes these days too) with some cameras you had no option but to use a filter, which is normally of a reddish magenta colour, to restore colour balance to your underwater shots. And they work fine as long as you understand that they only really work within a very narrow band of depth, typically around 8-12m. This is because as explained in our earlier white balancing blog, our colours are diminished progressively as we get deeper, so any fixed method of colour correction such as a filter is really only going to work efficiently at one depth. And we would need a collection of filters of variable intensity as we got deeper, which is impractical to say the least.
To be honest, unless there is absolutely no alternative with your camera (GoPro’s and other cameras of this type fall into this category), I would steer away from conventional colour correction filters because they also steal quite a bit of light from you. Or as in the cases below only shoot with them really shallow – no deeper than around 8m – for the best results.
Some cameras have a dedicated underwater mode, but this is usually little more than an electronic version of a coloured filter and doesn’t always do much, but of late I’ve seen some more promising offerings of this sort of thing from Canon and Olympus.
Here’s a video I shot using the underwater mode on an Olympus Mirrorless camera, an EM5:

Shooting in the RAW
Probably the very best way to colour correct your pictures, even if you have the option of custom white balance, is if your camera will allow you to shoot RAW files.
Now if you are not sure, the chances are that your camera won’t, as the ability to shoot RAW will be something you will probably have looked at when buying a camera, and also the salesman will have made a big deal out of it, because it is a big deal. So you know what to ask for when you purchase your next camera.
RAW files are simply the actual data recorded at the sensor and are not processed into a jpeg file within the camera.
The means that you can have full control after you’ve taken your shots to process the pictures yourself, and really fine tune things like colour correction, white balance and even exposure to a lesser degree. This processing you would do within a program like Adobe Photoshop or Adobe Lightroom, and this is why things like RAW shooting are available to people with high end compact cameras or Mirrorless and DSLR shooters.
It’s nothing to be intimidated about and processing RAW files is a relatively easy task, and is also quite fun too. A bit like the modern equivalent of having a home darkroom, but without the dangerous chemicals and fumbling around in the dark!
Macro Photography in Available Light
Underwater macro or close up photography is often thought to be only practical if you use extra lighting of some kind. If you encounter subjects that are in good light like the Hawkfish below, then there is no reason as long as your shutter speeds and apertures of your camera will allow to shoot with what the sun is providing for you. This can often be simpler and produce more naturalistic results.
So keep an eye on what your camera is telling you, and if the camera shake warning is flashing then you may need to up your ISO’s to provide a suitable shutter speed to hand hold. On that note hand holding close up shots is more tricky than wide angle so you may need to pick (or force shutter speeds with a higher ISO) than you could get away with with a wider lens. I try and keep above 1/250 of a second if shooting like this.
Fish portraiture like this is perfectly achievable using available light, and allows you to capture the subject exactly as you see it. The things you need to watch out for are that your shutter speeds are sufficiently high enough to hand hold your camera set up, because in macro mode you may also be zoomed in slightly so any movements you make will be magnified. These two shots below were typical examples of pictures where I wanted to get the shot exactly as I was seeing it, and whilst the Crocodile Fish is only just qualified to be called a macro picture, everything I’ve said above applies.
Available light wreck shooting
A very popular subject for available light shooting is to shoot big expansive wreck photographs, and often shooting available light is the only way possible to light such a large object, because even with the most powerful strobes it would be nigh on impossible to completely illuminate a large subject like a wreck. Unless the light conditions are in your favour, and the wreck is positioned so that the sun is directly illuminating it, when you want to shoot it, then getting your colours correct will depend hugely on all these variables. Just one of the reasons why people often choose to turn their wreck photographs to black and white – this not only heightens the drama and mood but is often the only get out clause to avoid weird colours, because the conditions are not in your favour.
For the stern shot of the Thistlegorm, I have actually used a little bit of flash, but it has only slightly lightened the very closest part of the wreck, and lifted it a little. To all intents and purposes the shot is being mostly illuminated by the late afternoon sunlight.
So I will leave it up to you which you prefer, the straight shot or the black and white toned version below it:
The side on shot which is an unusual angle. I have given you the straight shot at the top with little or no editing, and then the more stylised black and white version below it:
Another alternative is to come on a dedicated wreck photography week where we will often dive the same wreck many times throughout the day to raise the chances of good lighting. I spend a lot of time on these trips teaching people how to edit their pictures, with black and white editing particularly popular.
I hope you’ve enjoyed this series on available light shooting. If you’d like to ask me any questions or talk about our photo trips please drop me a line at duxy@scubatravel.com.
