Long story short, I am contracted to do a very informal tiny wedding this coming Saturday. I have a contract with the couple. First line of the contract they both signed stated I own copyright to all images, not to be reproduced or distributed in print or digitally without my explicit written permission. I did a free engagement session when they booked the wedding, and took their 50% non-refundable deposit to hold the date. Posted the portraits in a gallery on Backprint for them to order from. They ordered one poster sized image and that was all so far, asking for an extension on the order deadline citing budget difficulty because of the wedding (which I did) I met with the bride this morning and went over last minute details. This afternoon I discovered the bride has circumvented my watermarks and posted all of the engagement pictures on Facebook. (Apparently there is a glitch on Backprint where you can view the portrait without the watermark to custom crop, something to take up with them on Monday) I contacted the bride who also admitted they tried to print at home, but images printed with the watermark. She admitted to posting the pictures and said she knew that was unacceptable based on the terms of our contract. She made no apology, but did say she would take them down. I also contacted Facebook to make sure they are taken down. Anyway, I don't know where to go from here. I have only sold digital files once, at a fee of $50 per file. She took 37 files. I now believe she would do the same with any images from the wedding, since she seems unapologetic and says she knew it was breaking our contract to do it the first time but did it anyway. Now what???
