I can't quite grasp how the pricing seems to work. iStockphoto.com charges $1 ShutterPoint.com lets the artist choose the price, and the min. is $20. What's more...iStock has a tough scrutinizing eye and rejects photos they don't deem worthy, while ShutterPoint allows anything the user sends up. Also, Shutterpoint costs $25 a year, iStock is free. Please, can someone tell me why I would possibly choose one over the other? Can anyone recommend a good stock site to submit my photos to?
