Welcome to Steemit @justyna! I hope you have a good time posting here. I enjoy photography myself. D90 is one of the best Nikon SLRs in the past decade. I've had the pleasure of using one courtesy a friend briefly.

This is a great community and hopefully it'll prove to be helpful and useful for you in your endeavors. Feel free to ask any queries you have. Steemit Chat is also a great place to network and collaborate with like minded people.
