Those are my "Top performers" at Shutterstock until now (March 2018). For each of these photos, I earned more than $20.

As you might have noticed, almost all of them are wildlife picture. People say that wildlife pictures do not give good microstock income but in my case it seems to be the opposite. Maybe wildlife is the only thing I can take good pictures off.

Anyway, if you want to sell your pictures and videos online and to give microstock a try, then I recommend Shutterstock. The registration is very straight forward and you can fill it here. It is free, and quick, nothing to lose, except your time ;-)
Another option that I tried and I managed to sell few pictures is Fotolia. If you want to register at Fotolia then click here
I tried Dreamstime as well but it was a disaster. However, who never know maybe Dreamstime is the one for you. If you want to give Dreamstime a try then you can register here

May the camera be with you!
