Lenses and Filters

One of the best investments you can make as an underwater photographer is in quality lenses. Your lens selection becomes even more important because not all lenses are practical for underwater photography. We have limited the lenses in this section to only the ones that are appropriate to underwater use.

Filters are attachments that go over the front of the lens. They produce photo effects and help reduce certain issues by 'filtering' what the lens sees. With digital photo enhancement the way it is today, many people don’t believe they need filters. However, there are just some things you cannot change, even with a photo editor. Underwater the camera needs the addition of a red filter to help correct your images from being all blue or all green. Every diver has noticed that the underwater environment is one of the monochromatic hues rather than distinct colours. Depending on your location, objects will take on a blue or green cast at the expense of all things yellow, orange, red, etc. This is because water acts as a filter of red light. The deeper you dive the more the red spectrum is filtered from the ambient light. You can, however, emphasise the existing red light by filtering out the blue spectrum with a red filter of the right hue for the water type and depth.
