Well we are now hopefully aware that to take good available light shots, we need to get close to our subjects, and if they are larger than a typical fish ID pic then we probably need to think about using a wider than normal lens, as explained in the first part of our series here.
And then we need to address the issue of getting blue pictures when what we would like is bright colourful pictures showing the whole range of the spectrum, and this we looked at in part two.
What happens when things don’t work out?
And more importantly, how do we learn to figure what makes a good situation for using available light, or when we still want to shoot with available light but our colours aren’t as good as we would like, despite our best efforts at white balancing?
In an ideal world, all of our available light shots would be taken around half ten in the morning, with the sun behind us, camera pointing very slightly downwards, in about 8 metres of water.
This is an unrealistic expectation though. And of course we can’t possibly guarantee this. It’s helpful to know that Custom White Balance doesn’t always produce the goods.
Folk often get flushed with the success of their early attempts at Custom White Balance, but after the honeymoon period has worn off, they can often become jaded with their results as time passes.
This is for a number of reasons I have found.
First and foremost they have unrealistic expectations of what custom white balance is capable of doing. And this coincides with them becoming more critical underwater photographers as they gain more experience.
To solve the first problem they need to draw on their new found skills and adapt how they shoot available light.
A very common problem is shooting towards the light rather than away from it, and this tends to cause over exposure with an automatic camera, as it tries to expose for the subject occupying the majority of the frame. This then results in the background – either the sand or the surface – taking on a horrible magenta or pink hue.
This is because the colour correction that the custom white balance is introducing is only accurate for the correctly exposed foreground. The background goes like this, as both a combination of overexposure, and also that the surface is shallower requiring less aggressive colour correction. There’s nothing wrong with your camera; it’s just physics working against you.
When it all goes horribly wrong!
If you overly rely on Custom White Balance to sort out your colour problems, you will inevitably end up with shots like this one above. Poor exposure balance and the overexposed background with the sun shining towards you will be marred with a horrible colour cast. This is not a fault of your camera. The camera is only trying to do what you are asking, but it’s the circumstances that are less than ideal.
So, how do you manage this? Well first try where possible to compose and shoot with the sun behind you. And try and shoot slightly downwards using this technique too.
There’s nothing wrong with shooting into the sun – in fact it’s great for silhouettes and dramatic sunbeam pictures that are strobe lit, just not for available light. You just have to teach yourself when it is and isn’t going to work.
If you are shooting into the sun, then silhouettes are a good example where you have to be very careful when custom white balancing. This shot of a lionfish was taken on a point and shoot Canon camera nearly 8 years ago. I locked my exposure using a half press of the shutter release, whilst pointing at the brightest area, and based my white balance reading not on my hand or the subject, but on the surface water itself. Helping prevent those awful white balance issues shown above.
Another problem with Custom White Balance is that we forget to change it when we change depth, and this becomes more apparent in the shallows, nearer the surface; and our shot is spoiled by the amount of correction applied say at 10m being much too much when we ascend to 5m. So you must remember to get familiar with the procedure and take new readings as you change depth.
Depth Perception is a common fault when using Custom White Balance, as is forgetting to regularly change your White Balance settings as you change depth. If I didn’t have to already tell you, the shot on the top (above) is the result of taking a picture without white balancing after shooting previously at a greater depth. The shot at the bottom is the same view, but correctly white balanced.
To solve the second most common issue with available light shooting, we also need to draw on our prior experiences.
As we become more capable photographers, starting to get lovely colourful pictures in bright conditions, we need to understand that the camera will lull us into a false sense of security, and the success we see at the shallower depths, i.e. from the surface to around 12m, isn’t as well replicated as we get deeper.
This is because although custom white balance, at least with some camera brands (particularly the Canons) seems to do a remarkable job at ridding us of the blues, it really can’t work magic; and as we get deeper, the colour and amount of light diminishes.
So along with the colours not being as great, what can happen when we go deeper, especially if we are using a fully automatic camera, is that we start to see blur – and camera shake appears.
Who turned out the lights?
Why? Well our eyes and brains are very good at adapting to the steadily diminishing light, and even though it may only look a little darker to us when we go from 10 to 20m, the camera is starting to struggle as the light is much less than we are experiencing.
The trick is to keep an eye on what the camera is telling you; even the most automatic cameras will show you what shutter speed that they are picking, and more importantly, if you are straying into the danger zone, i.e. the shutter speed is too slow to easily hand hold the camera, or that there may be a risk of camera shake or subject movement.
Usually this is a red warning light or a symbol of a shaky hand, or the data or the shutter speed will be highlighted in a warning red colour.
Check in close detail
When we look at the small image on the back of our camera’s screen, at first glance (top pic) everything may seem OK at this small size. However it’s worth zooming into your shot to see if it’s spoilt by camera shake as it clearly is above (bottom pic). Sometimes things may seem bright to us, but they really aren’t as you can see if you zoom into the same shot and see the telltale blurring of camera shake. So don’t assume everything is fine until you look closer.
This can be helped by increasing the ISO settings on our cameras which will force the camera to pick faster shutter speeds and also help reduce the blur in our subjects.
There is a side effect to increasing the ISO though and that’s more grainy or noisy pictures, which looks like this:
Shooting in lower light
Same scene as before, but this time to rid myself of the camera shake I’ve chosen a very high ISO to force the camera into picking a faster shutter speed, thus eliminating the camera shake. Unfortunately though we’ve introduced another problem. And that’s digital noise, which is exacerbated by high ISO’s and low light, and renders the picture virtually unusable as you can see from the enlarged section in the bottom half above.
OK, to be fair I’ve used extremes at either end of the range here to highlight the issues, but once you learn exactly how much, and no more, to raise the ISO’s to give you workable shutter speeds in lots of different scenarios, you are halfway to being able to really get to grips and control your camera in a wide variety of circumstances when available light is your choice (or sometimes only option).
To summarise, try and take your available light Custom white Balanced shots in good light and preferably with the sun behind you. And also be aware that although the camera will let you shoot at lower light levels, the results when you get them back on your computer may be spoilt by camera shake and subject movement, so increase the ISO or take your shot shallower if possible.
So in part 4, I will be looking at other ways to colour correct your pictures, and options you may have but not realise, along with examples of what to do when you can’t colour correct things properly.

Ocean Art 2020 Winners Announced!
Ocean Art Contest Announces the Best Underwater Photos of the Year
The prestigious Ocean Art Underwater Photo Competition, organized by the Underwater Photography Guide, has announced the best underwater photos this year with its 2020 winners. Despite global travel restrictions and the challenges brought by the Covid-19 pandemic, the 9th annual competition attracted an extremely high caliber of photos from oceans around the world. Underwater explorers captured photos locally, in select destinations currently open to travel, or revisited their archives to bring us some eye-catching photography. This unique assortment of photos could not have been possible without the help of our generous sponsors who have all had to navigate a changing travel and dive industry. Many of these same sponsors helped the Ocean Art competition raise money earlier in this year to raise money to donate to the WHO and CDC in their fight against Covid-19. These photos showcase the perseverance of underwater artistry amidst the adversity of the times.
All the winning photos can be seen at the Underwater Photography Guide at https://www.uwphotographyguide.com/ocean-art-contest-winners-2020
The Best of Show is a once-in-a-lifetime moment of an octopus taking a selfie with the photographer and his curious family in the background. The photo was captured by photographer Gaetano Dario Gargiulo close to his home in the tide pools of Kamay Botany Bay National Park, New South Wales, Australia. Other extraordinary winners include astonishing scenes of animal behavior, images that bring hope for the next generation of sea creatures, displays of ingenious photographic technique, and conservation scenes that reflect on not just the need to conserve our planet, but our species as well. The judges evaluated thousands of entries from 80 countries before selecting the final set of images as Ocean Art winners.
Ocean Art 2020 judges included prestigious underwater photographers Tony Wu, Mark Strickland, and Marty Snyderman.
Over $45,000 in prizes have be awarded, making the Ocean Art prize value among the highest in the world.
Ocean Art prizes are provided by some of the world’s top scuba diving resorts, liveaboard dive yachts, and underwater photo gear manufacturers. Grand prizes include a choice of 7 or 8 nights for two aboard the Coralia Liveaboard in Raja Ampat or Komodo, a 7 night liveaboard trip on the M.V. Bilikili in the Solomon Islands, a 7-night dive package with Villa Markisa, a 7 night dive package at Siladen Resort & Spa in Bunaken, a 12 night Passport to Paradise with Murex Dive Resorts and Lembeh Resort to three different Indonesian destinations, a 5-night dive vacation with AquaMarine Diving Bali & Ramayana Candidasa, a 7-night dive vacation at Atlantis Philippines Dive Resorts, and a variety of gift certificates from Bluewater Photo and Bluewater Travel. Premium travel prizes are provided by Volivoli Beach Resort (Fiji), Crystal Blue Dive Resort (Philippines), and Solitude Liveaboards & Resorts (Philippines and Indonesia). Premium gear prizes are provided by Sea & Sea and Ikelite. 12 different categories ensure a competitive contest for all levels and disciplines of underwater photography.
The photographic ingenuity from competitors is getting better every year – making judging very difficult and demonstrating that the winning images are some of the best in the world. Bluewater Photo and Bluewater Travel owner and Underwater Photography Guide publisher, Scott Gietler commented, “The Ocean Art team was thrilled to see that so many photographers were able to get out, dive, and immerse themselves in photography this year. The Best of Show was especially impressive. My only concern is that the octopus should get its share of the prize, as it did assist in taking the shot!”
