I was asked to be a guest reviewer for the Houston Photographic Society, which holds regular portfolio review sessions for its members. The bulk of the membership does not work professionally as commercial photographers or fine artists, so I really wasn't sure what I would see in their work or what quality level their presentations would be.
I was very pleasantly surprised. The members whose work that I saw had put a lot of effort into their editing and presentation. They had come with artist statements, matted prints, and did not have too many prints to review in the time segments.
It's also nice to feel appreciated - I liked the presentation of their certificate to me in the 4x5 film holder!
