Thanks Ben. What is a likely sum for a local paper to pay?
No. By selling the photo you are selling the rights to the photo.
In answer to your other question: That all depends on the paper your selling to, the size they will print it, how many times is it printed etc so i would recommended talking to your local paper and find out what the average pay is for a photograph from a freelance photographer.
Any other questions feel free to email me.
The secret is not to sell the picture but to sell permission to publish a copy of it. This way you can sell to as many papers/magazines as you like.
