Hi all, I'm new on here and just wanted to pick your brains please. I am an amateur photographer, and recently took a picture of a friend and her horse which was posted on an internet forum. The manufacturer of a piece of equipment she was using at the time expressed an interest in using the picture in one of their brochures to advertise the item. They contacted my friend about it and she directed them to me to ask for permission. I granted permission, and was extremely flattered that they thought the photo was that good! A couple of weeks later they contacted me again to ask to use it again in an editorial in a magazine to advertise their goods. I ummed and ahhed about it, and decided I thought they were taking advantage where they would normally have to pay a photographer for the shot, so I declined and on the advice of a photographer friend, invited them to make me an offer to purchase the rights to use the photo (not naming a figure). I received an email back from them declining, stating they didn't have the budget. A few days after this I found out they have used the photo for the editorial anyway!! Without my permission! Considering the timescale, they didn't even wait for my reply before using it, and may even have submitted the photo prior to even asking for my permission. Now I know very little about these matters, but I have done a little research and know that as the photographer I am by default the owner of the photo, and that they are in breach of copyright law by using the pic without my permission. So what can I do? To be honest I don't really want to get into some legal battle about it, and would be happy if they just paid me for the photo. But I don't know what the going rate is and what to do next. Thanks a million if you have managed to read through all that. I really appreciate any advice you can give me.
