Afraid I have to break the flow here. I used to sell, but it was far too much effort for a small return. Someone emailed me the other day asking for a print and I sold them one, but I really can't see the point. Unless you are
really good (and I'm not yet) you are not going to make very much. It can only ever be hobby sales. Pin money.
I would rather (and do) focus all my efforts on getting really good at photography, developing a style and techniques, and exploring as much as I can. I know that eventually, the right opportunity will occur - it always has in the past. Why waste time flogging a few prints to people who want something to match their sofa?
Sorry to be the lone dissenter.
