I have been contacted by a local midstock agency, one of their customers would like to use my photo in their trademark.
The product will be a new German beer.

I informed them that the photo they would like to use had sold almost 300 times. If it is no longer interesting to them, I have created an alternative picture, a montage with the same landmarks and a similar mood. The alternative photo has been forwarded by the agency to their client.

The question is how much should I request for the use of a photo in trademark and exlusive rights?
I'm a hobbyist and have no experience with such requests.
Your comments will be greatly appreciated.

thank you ap, that's an interesting thread

hello donding,
yes, they are negotiating with their client. They will certainly take their commission, but I trust them. If it works out they deserve a commission.
They have a good reputation and have always been fair to me.
No feedback yet though if the customer likes the alternative picture. Maybe they didn't expect that the first one had sold so often.
