Practice Practice Practice - along with a lot of Patience Patience Patience. After each dive - download the pictures and analyze what you think would improve the photo and then try to accomplish just that on the next dive. Also I worked on running all of the controls on my camera blind so that under the water I would not be fumbling trying to read the settings. Periodically we would accidentally change the settings on our camera during the dive. Make not of the colors as you shoot to make sure that you haven`t doen the same.
