She had two very good pieces of advice that can't be repeated too often....
"I feel strongly that a good photographer is also a moral one. Don't stage set your shot. If you move an animal to look better in the picture, you are likely killing the animal. If you need to dig a hole with your fist or fins to get the right angle, you are probably killing a lot of animals. Patience, Grasshopper, there's always another day and another nudibranch."

"Correct camera care does not work with romance, honeymoons, beer, or spur-of-the-moment anything. It requires consistent, anal-retentive attention to a small set of o-rings that determine whether or not you will love or hate your next dive. There is no escaping the rigors of o-ring care - it will not wait until tomorrow. Fortunately, you will not be alone - there are large groups of people on many dive boats that have their entire social, emotional, and psychological lives based on the common camera table - much like the quilting bees of old."
