Still, there are a few principles that can make even digital photography
better:

STEPHEN’S TIP 1: MINIMIZE BACKSCATTER

Backscatter is the most important variable in point-and-shoot photog-
raphy because the strobe is near the lens with most systems. Particles
in the water are front-lit by the flash and appear as specks of “back-
scatter.” These are some of the best ways to eliminate backscatter:

• Work in the clearest possible water. 

• If the water is dirty, find a busy, visually confusing background that

may hide particles. 

• Avoid shooting into the open water column, which will accentuate

particles. 

• Don’t make backscatter worse with poor buoyancy skills. Avoid 

stirring the sand on the bottom or dislodging the silt on a sponge.
