Finally I have 25 photos!!! I’m half the way to becoming a “photographer working exclusively with Dreamstime.com”. It’s really not so easy to start, so many rejects. I came to conclusion that there are several ways to minimize reject:
First of all analyze quality (sharpness and composition ). If they are not perfect, there is no need to waste time processing these pictures. If you doubt to send picture or not because of the quality, don’t send them. They won’t be approved. If you doubt because of the picture content, that will be a different question.
Secondly, If you processed the picture, scan it for trademarks. They might be so small and almost unnoticeable, but they will be an annoying reason for reject. Here is a good article every newbie should read - https://www.dreamstime.com/thread_148
