<p>I have been approached by a large construction company that wants me to photograph a client appreciation event. I sent over a contract that basically says you can't use my photos for marketing/advertising without explicit written permission. The company emailed me back saying that they would like to use these photographs for internal and external marketing purposes and what that would entail? I have tried to research as much as I can but I can't seem to find anything related to this issue. My question is how much extra should I charge on top of my hourly fee to allow them to use my photos for marketing? Even just a ballpark would help, I don't know wether it should be $50 an image, $1000 an image, $500 extra for all images, or nothing at all. Any guidance would be appreciated!</p>
