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.

A classic reef scene that could be taken with any camera from a GoPro upwards. This is unfiltered and what a lot of people experience when first shooting underwater.

Here the same shot as previous, but this time I’ve used a colour correction filter to restore the colours. Note however that I am very shallow and this is where these filters work best.

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!

This is an uncorrected RAW file taken on a Canon Compact camera, at around a 12m depth.

After colour correction within Adobe Lightroom, the RAW file has allowed me to completely restore the colours, but beware – this won’t work miracles, and at depths greater than 12m, it has less usefulness, and maybe using a strobe would be better.

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.

This Lizard fish is about as close as you could expect to shoot successfully without a strobe. These guys are often in very shallow water, laying on bright well lit sand, so are a very suitable subject for available light macro photography.

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.

Fish Portraits like the ones here shot using compact cameras and underwater white balance, or RAW files, is very possible in very bright light conditions.

Macro Photography is normally the preserve of someone shooting with strobes only, but as long as you are in good light Macro photography is possible.

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:

A shot at the stern, where I have been lucky enough to have no other divers in the scene, which if you’ve been to the Thistlegorm, you’ll realise is rare indeed. This is with only a tiny amount of flash lighting up the very closest part of the wreck.

The black and white version of the stern shot of the Thistlegorm. It’s a matter of personal taste which one you prefer. Making black and white edits like this is a question I get asked a lot on our photo workshops.

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:

This is a rather untraditional viewpoint of the Thistlegorm, taken sideways on at the bow. The picture is a little soft at the edges because of the wide aperture I have had to use to gain a sufficiently fast shutter speed to hold the camera steady.

Because of the wide aperture I used which has softened the edges somewhat, I decided to opt for a black and white edit which actually highlights the softer edges to try and give it a dated and otherworldly feel.

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

An update from Bunaken Oasis Dive Resort…



The team from ‘Indonesia’s Leading Dive Resort’ let us know what they’ve been doing during lockdown:

On Friday March 20th 2020, we waved goodbye to the last guests to leave us before Covid-related travel restrictions were introduced the following day. We suspected that global tourism would be effectively shut down for the rest of that year, but here we are over twelve months later, with no certainty as to when we can welcome our first international clients back to Bunaken.

We have not, however, been idle.

Our primary concern was for our staff. Having over 80 staff on contract, together with no revenue, gave us a dilemma. We immediately told all our employees that no one would be losing their job. To achieve this, we put everyone except senior managers on 50% salary in return for their working 50% of their contracted days. But with no guests and 40 employees present at any one time, how would they fill their days?


Having been voted ‘Indonesia’s Leading Dive Resort’ by the World Travel Awards for the last three years, we knew we couldn’t simply close our doors and wait for the world to return to normal. We’re a jungle-based, coastal resort, and what we know for sure is that sea air and jungle encroachment (however good it smells and pretty it looks!) are no friends of ours. For the last year there’s been constant activity: painting, deep-cleaning, polishing, trimming, pruning, overhauling, servicing – so that when we’re ready to open, every aspect of the resort is in first-class condition

In addition to maintenance and refurbishment work, and with our new General Managers Ed Regeer and Shu Ming Chueng leading the way, we embarked on a comprehensive schedule of projects to improve and upgrade the infrastructure of the resort: re-roofing cottages, rebuilding walkways and bridges, reinforcing the jetty, refurbishing our dive boats, enlarging our organic garden, and rebuilding perimeter fencing.

Ed & Shu

As well as improving the resort and keeping our staff employed, this has also provided benefits to the local economy; we regularly employ additional craftsmen on a week-by-week basis, and nearly all raw materials are bought in Bunaken or nearby Manado.

But there are other ways that the resort has continued to support the island and the local community: because we make our own fresh water (the only fresh water on Bunaken), we supply it to the local villagers, and we also provide electricity and fresh water to the nearby Balai ranger station. We have devoted labour and materials to assist the repair and ongoing maintenance of the main arterial road (albeit it’s a motorcycle path, as there aren’t any cars on Bunaken!) that links the three major villages on the island, and we have expanded our mangrove planting programme.

We also continue to provide emergency medical evacuation to the mainland for anyone who needs it, and our Emergency First Responders are occasionally called upon to administer first aid to islanders who have been involved in motorcycle accidents in the vicinity of the resort.

Finally, and like any other diving resort anywhere in the world, we are fighting a continuous battle against the garbage which so thoughtlessly ends up in the ocean, and which then sometimes washes up on our doorstep. As well as cleaning up our own beach and mangroves, we assist other resorts in cleaning up theirs, and we contribute regularly to the brilliant efforts of Trash Heroes Bunaken.

While we may not have had any guests for the last year, we’ve certainly been extremely busy, and this means that Bunaken Oasis Dive Resort will be in fantastic shape to welcome new and returning guests as soon as restrictions are lifted, and international travel begins to return to something like normal.

We’re operating an extremely flexible reservations scheme, with currently only 10%deposit. For more information, please visit or contact

On behalf of the owners and managers of Bunaken Oasis, we’d like to say a huge thank you to those guests who had booked with us but have had to rearrange their holiday plans because of the pandemic. Given the ongoing uncertainty, we’re happy to reschedule your dates as needed, and we look forward to offering you the warmest Bunaken welcome just as soon as we’re able to!
