What kind of photographer are you? Are you a food shooter or do you take portraits? If you're a portrait photographer do you take family portraits or editorial photos?
I get asked these questions fairly often and the best way to answer them is with a simple "yes". I definitely have preference of subject, but when it comes to making something in front of my lens look good it's the lighting that does all the work. Once you have an understanding of how to work with light, it doesn't matter if your subject is three inches tall or life size, the lighting arrangement will be the same.
