I agree that business shots are much more popular, but it is not rare to see DT nature images used in several magazines I get, neither being an extremely popular magazines. Seems that magazines like OP and NG prefer to use pro shots instead of microstock. I have only sold about 20 photos (all of them being various nature categories), but I haven't come across any yet. I don't shoot photos for the purpose of earning money, otherwise my portfolio would be drastically different. I photograph what I enjoy and try to make a little money off of it to lower the equipment costs.
