The Strobist - An informative site which exhibits the beauty of using portable lights to get gorgeous results.
Canon - The overall Canon system is great but I really love their lenses for their durability, unparalleled image quality and large apertures. I shoot with at least one Canon 5D, depending on the project. The 24-105mm L is my all purpose lens, complimented with an array of primes.
Pocket Wizard Radio Remotes - Safety is always a concern when photographing children. Radio remotes eliminate both wires and the possibility of tripping when I use studio strobes. Besides, babies and toddlers love to push the button that triggers the flashes .
Pelican Cases - Okay so this has nothing to do with digital technology, but when I'm playing with kids all day, I gotta have something that keeps them out of my camera equipment.
