Be ready for long post, sorry! I recently attended Formula D Round 5 in Seattle. While attending (in general admission, couldn't receive media credentials for the event) I had my camera and was taking pictures anyways. I also had a friend introduce me to a particular Pro FD driver and his media guy, after talking and shooting the **** I agreed to show the media guy any pictures I got of the driver throughout the event. The driver is sponsored by a very large automotive parts company. I ended up getting some good pictures of the driver throughout the event and ended up watermarking and sending the driver's media guy (as well as the company's media guy) the photos. He assured me at the event that if any of my pictures were to be used in any way he would give me credit. Fast forward to today.. I am now friends with both the driver and media guy on facebook and the media guy ended up posting a new advertisement piece (for the company) using various pictures from Formula D Seattle. Including one of my pictures (easily identifiable). Nowhere was I given credit, nor was I paid for the piece. My watermark has been removed from the photo as well. I contacted the Media guy asking what they planned to use the piece for and was told "Facebook and Webpage Advertisement". I replied to the guy saying that it would be awesome if I could get photo credit since they are going to be using the piece, to which I have received no reply. I was talking to my buddy who is also a photographer and has been paid to go to events and he mentioned that all of what has happened is "illegal" since the company's media guy took the photo without giving credit or paying for it. So my question to you all is, what do you think of the situation? Do you have any course of action suggestions? Thanks for your time!
