You're absolutely right that it's a great way to self-promote. Promoting yourself just means getting your name and work out there.

My husband is an amateur musician, and was telling me yesterday that he plans to do something new at his next performance. He is going to offer a free CD to anyone who emails photos or video from the performance.

This post of yours made me thik of that. Keep on shotting those photos.

(Reading the passion you have for your photography really makes me wish sometimes that I could see it. I view this as a good thing. You make your art come alive!)
