under water cam, I assume
if so, did it have a flash and how close was it/them
I had dove in cozumel and many pics that we took did not turn out, unless close. the water realy filters out the light and makes photography difficult at times. A good camera and flash for anything beyond probably 5 ft works best. Or different speed of film may help, most disposibles are only 200 maybe 400 ASA.
We had a good opportunity to take a pic of me wiht a 6+ft cuda, but without a flash, it is hard to make out even though it looked good in person. We only have a slight silhouette. My wife was only about 8 ot 10 feet away at the time. Now we have a better camera
