Thank your the welcome and the advice. Yes, backscatter is an underwater photographer's nightmare. It is indeed the small particles in the water (i.e. plankton, etc.) between you and the object that reflect the light from your strobes back to the camera lens. There are various tricks to avoid it with strobe placement, but I regularly need to do some editing when the pesky stuff creeps into my shots. Sometimes there is more backscatter than others and it would be great to know some of the best approaches in Affinity. I shall try the solutions suggested. Thanks once again.

Could anyone help me with advice on the best/easiest way to eliminate backscatter from my underwater images and also I would be grateful for some advice on how to alter exposure/brightness on just a small section of the image. For example a white fish belly that reflects back far too much light from my strobe compared to the rest of the image. Many thanks for any suggestions.

Hello, I have just bought Affinity Photo and am slowly trying to learn to use it. I'm a very keen amateur underwater photographer and previously have only edited my photos on iPhoto. Since updating to El Capitan, I have lost iPhoto which Apple (in their wisdom) have replaced with Photo. Hence my need for better editing software. I am a real novice, but am slowly picking up the facts, mainly thanks to the great tutorials. I do have a couple of questions, mainly related to the most common problems associated with underwater photography. The first big problem is backscatter and I would be very grateful for some guidance on the best/easiest way to eliminate it from my images and, secondly, I sometimes have small areas of the image which are overlit because my strobe was not properly positioned . Is there a way to change the exposure/brightness on a very small area of the image? For example, a fish might have a white belly and the strobe light from this will be reflected much too brightly compared to the rest of the image and so I would only want to alter the exposure/brightness of the belly of the fish. Many thanks for any suggestions!
