Stock Photography

The thing that I had not fully realised was that stock photography libraries are not looking for artistic photographs.
They want photographs that are interesting to their buyers. I've now submitted around 50 photographs to Dreamstime and only had 4 accepted. Some of them were frankly not up to my usual quality, but most were rejected because Dreamstime already have more than enough images of that particular subject.
It just goes to show that to make money from Digital Photography you need to know what your customers want. Equally you can save a lot of time and effort by not photographing subjects that are not going to sell.
