Hi there... I am normally a natural light outdoor photographer, but have been getting requests for indoor on-location portraits. I'm looking for a *simple* and inexpensive way to do some indoor portraits without having to lug around a ton of stuff. Plus I'll be photographing children and don't want a ton of equipment to make it feel to "stiff" -- I want it to be as informal and relaxed as possible. I have a Canon DSLR and the Speedlite 580 flash that I've been using on camera (hotshoe mount), so I was considering getting a large reflector and stand, and bouncing the flash off of that for some nice side lighting. Any thoughts on that approach or recommendations? Thanks in advance!!!
