I am definitely drawn to both dark and light styles of food photography, perhaps equally so. For me, dark has a certain richness that light lacks, while light has a fresh and clean feel that I also love.
One of my current goals is to learn how to mimic that kind of low side-light with artificial lighting. Ah, it's nice when it comes close to happening naturally though (like below at our table at Tribeca Grill — if I could modify the light there, I'd pull the imaginary shades down even a bit more until the light stops wrapping over the top of the food).
For my "light" example: I had a tiny bit of black sesame ice cream left from my pint from the Chinatown Ice Cream Factory; alas, scooping it with a rice paddle spatula does not yield a pretty scoop! (Not that I was expecting it to. This is more to illustrate a point :P.)
What about you — are you more drawn to one style over the other?
