I love your photos, they're very powerful and each one in its own unique way. If I may ask, what make of camera do you use and lighting set up?As of right now... I shoot with a Canon 30D,
and my primary lens is a Canon 28-135mm IS USM.
I'm looking to buy a much wider lense though.
For lighting... I have a little 1500watt Smith Victor thrifty kit
(3 lights at 500watts each, w/ white umbrelllas.)
that I purchased a while ago. They were very inexpensive. ($200)
I'm not very experienced with studio lighting,
so I didn't want to buy some very expensive set.
Once I do this more and improve at it,
then I'll upgrade to a nicer set of lights. (:
In some photos, (like the photo of the boy above),
I used my Canon Speedlight 430ex flash.
I like to fire it remotely, or with a "off-camera" 3ft cord.
