During a recent foray to Hawai’i to give seminars and workshops for the Canon Explorers of Light, I knew I’d be doing some snorkeling. (Hey! Somebody has to do this job!) I’ve previously used PowerShot compact digital cameras with underwater housings.

Commercial Vs. Editorial Uses • Sharp To The Edges • Extended Macro • TILT!

In the August 2009 issue of Outdoor Photographer, you discussed the difference between commercial and editorial uses of images and the need for releases.
