A photograph I recently took of the Quincy Bayview Bridge has become exceptionally popular locally as of late. I'm glad; I put a lot of work into this photo, which I primarily shot for a website I'm building.
I posted a secondary photo I had shot (while adjusting exposure and focus before the lights came on) on Facebook, and a buddy of mine who works at the newspaper asked if I had any others that he could use for the Quincy Herald-Whig Answer Book cover (Quincy natives should check out David Adam's Answers Blog, which is the source material for this book). I sent over 2 others, and he chose the one you see above.
Then, I got asked if it could be used in a story on Whig.com. And as part of the promotional ads run in the Whig.
They all asked, and offered to cite me as photographer. They asked, so I obliged, glad to help out my friends (disclaimer: I work for Quincy Interactive, which is a part of QNI, which owns the Whig).
Later, The District posted an ad utilizing my photo on Facebook, which didn't contain my photography credit.
This is where things got a little hairy; While I don't mind people utilizing it, there were a few requirements.
Number one, I wanted credit for the photo, if nothing else. I need to build my name back up as an artist locally, since I've been out of the art scene for a while.
Two, I need money. While I didn't get compensation from the Whig, I was mostly helping out friends. I've been debating on whether to sell this photo as stock, or as a print. When The District posted it, I had to debate how to handle it.
Ultimately, I asked them to post a link to my piece for sale with the next FB post they make on the bridge lighting (which is tonight). Having them add it to the previous post would be pointless, as it has basically already hit it's maximum reach. Still, if I can sell a few prints, I'll be happy. The District had no ill intent, and had no idea that I was requesting credit for the work.
Something to consider when sharing your work is its value; You may find that, while it isn't as valuable to you, others may find it worth much more. While it's great to be altruistic in sharing your work, you do have to remember that it all costs money to produce. I myself am finally working towards purchasing a new camera (after using the same one for approximately 9 years). The time and equipment all cost money, regardless of how much you love what you do. So, retain your photography copyright, and enforce it as much as you're willing to.
