Many photographers have a sideline as photographer retailers or framers, so they can sell their work. Of course, this won’t be appropriate if you have photographed a wedding or party, but if you also work with landscapes and objects, it can make you some extra money quite easily.
The most important thing to remember is presenting your images beautifully so that they appeal to your buyers. You should frame photographs in beautiful frames – something quite simple, metal maybe, that isn’t going to detract from the photo itself but that is going to set it off and make it look lovely. You can buy sets of photo frames online for a much lower price, so you can keep your costs down.
Don’t charge too much at first, then as your photo retail business grows, you can begin to charge a little more. Give people the time to get to know your work, and it will begin to happen naturally over time.
