I've just returned from my first few dives with a camera. I, like many other amateur photographers went out and bought a housing for my land based canon elf. As you could imagine my first set of pictures came out extremely blue, loosing a lot of the color anywhere deeper than 25 feet. I was shooting in the Caribbean anywhere between 25 and 65 feet. I was told by the DM that getting a red filter would correct this, also I noticed others onboard with filters on their cameras.
Is a red filter necessary and if so when do you use it? Can they be put on underwater? Can the blue be corrected using the ISO and white balance settings instead? Or, should you set the ISO high and the white balance in addition to using a red filter or is that going to be too much correction?
