Be The Best "You"
But, in Dreamstime especially, that crowd is VERY, very large. So how do you stand out?
It's all about exploiting your unique skills and opportunities. For example, during a fishing trip in Nunavut, Canada, I took a very basic landscape photo of the Arctic Tundra. I have since sold this image on Dreamstime several times over, and will no doubt continue to see revenue from it into the future.
Why? Simple - not a lot of people have stock imagery of the Arctic Tundra. And I've found many of my most popular images have come from "unique" shoots, rather than "technically spectacular" shoots.
So - what special opportunities can you exploit?
