Wonderful photographs. Glad to see some of your work on Shuttershock. It is on my long list of things to do in the future.
How is your experience there? Have you thought about doing a post on using sites like shuttershock to sell photographs. I have a folder on my computer where I am placing some of my work that might be candidates for such a venue.
Do they allow one's logo on their photos?
Probably I'll do a post about Shutterstock in the near future. My advise is to start as soon as possible!
