I've started doing some event work with my 8x10 camera, and I've been asked to set up at a fundraiser soon. These will be smartly dressed people looking for a unique portrait. The challenge (I refuse to think of it as a limitation) is that I won't have much space to work with. I'm looking for examples or aesthetic ideas where the subject is more or less against a white wall. I'm thinking maybe harder light with a well defined shadow. Thoughts?
