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.

DISCLAIMER: No claim is made by The Scuba Doctor as to the accuracy of the dive site coordinates listed here. Should anyone decide to use these GPS marks to locate and dive on a site, they do so entirely at their own risk. Always verify against other sources.
The marks come from numerous sources including commercial operators, independent dive clubs, reference works, and active divers. Some are known to be accurate, while others may not be. Some GPS marks may even have come from maps using the AGD66 datum, and thus may need be converted to the WGS84 datum. To distinguish between the possible accuracy of the dive site marks, we've tried to give each mark a source, e.g. GPS, Google Earth, or unknown.
If you don't understand the differences between the different ways coordinates are given, plus how different datum come into play, you might find the article GPS Conversions by Lloyd Borrett a useful read. It describes the problems associated with locating dive sites using a GPS receiver.
