As some of you have noticed, this weekend I began placing a "watermark" on my photos. This was done reluctantly, in an effort to protect my photos from misuse. I first purchased the software in April, after a conversation with Di Mackey, a friend and professional photographer in Belgium. For months I resisted using software (Corel Paintshop Pro Photo XI) to layer "watermarks" over my photos, as I find their placement distracting.
In the past few months, I have discovered several instances of my photos being used without credit and for profit - someone else's. The last straw came when a friend published a lovely collage of holiday photos - including mine - she'd found on Flickr. As I had not posted any photos on Flickr, I investigated further. Turns out, someone else put my photos on Flickr, claiming them as their own. I now feel forced to use "watermarks" as discreetly as possible, so as not to distract from the photos. Another watermark is embedded electronically within the photos. Have you experienced similar cases of people using your work without permission? If so, how have you reacted?
