![]() No underwater filter can work at all depths because the filtering effect of seawater increases rapidly as we descend. One of the most obvious differences in filter images is that color penetrates deeply into the shot, making them ideal for reef scenes stretching away from the lens, a school of fish coming towards it or a shipwreck or big animal that is just too large to light any other way. ![]() Filters work best on sunny days, when there is lots of light, although now that most cameras perform very well at medium and high ISOs, they can be used in far more conditions than in the early days of digital. The best subjects for filters are coral gardens, divers, wrecks, big pelagics, and schools of fish. However, once you are deeper than 3m (9ft) the advantages of a filter become more and more apparent.įilters allow you to dive without cumbersome strobes and arms yet still get very natural colors easily ![]() When you are very shallow, just below the surface, in the top 2-3m (6-9ft) then white balance alone is absolutely fine. One question we get asked a lot is what is the advantage of using a filter, compared with just using the camera’s manual white balance alone. Probably most exciting for photographers is that filter photography adds color to images in a different way to shooting with strobes and many of the most memorable filter images are ones that just can’t be replicated with strobes. They also provide the chance to take a different type of image and diversify your portfolio. Like any techniques, they are about adding another option to your arsenal of skills-something to be used with suitable subject matter, in suitable conditions. Why Use Filters for Underwater Photography?įilters are an alternative to shooting with strobes, not a replacement. They are now mainstream and we truly have another way to shoot colorful underwater pictures.įilters produce colors that penetrate deeply into the shot, making them ideal for wrecks and reef scenes stretching away from the lens When used on film cameras, filters were hit and (mostly) miss but now we can fine-tune every shot making them one of the most dependable of all underwater photography techniques. Furthermore, filter photography underwater benefits hugely from the adjustable white balance of digital. ![]() Underwater, the situation is different because we’re using much stronger filters than on land because we have to deal with much bigger color shifts. There, as the capabilities of digital cameras and software have grown, so filter use has become less popular. Filters are not new to underwater photography, but they have come of age with the digital revolution. ![]()
