As of yesterday, I had over 100 images approved on ShutterStock, arguably the 2nd hardest agency to get images approved at. Maybe the 3rd. iStock is the 2nd, with the first being Fotolia. The reviewers at Fotolia are extremely picky. They’ve rejected images which are *big* sellers on the other sites.
It’s a nice way to make some cash from photography, if you can shoot suitable images.
The photograph must be of high technical quality, tack sharp focus, and usually bright and colorful, with a clear concept. My shots of a glass of soda are selling like crazy.
If you want to make money with your photography, try
ShutterStock first. That link is to the referral program. It tells them I sent you!
