what to charge someone for use of my photos without specific permission
A guy I work with asked for some of my photos to put in his book he is writing. I gave him a disc , some pics had watermarks some did not. I asked him not to share these since I "sell" my photos. Told him I would only charge $8 each photo for onetime use in his book. Several months have gone by and he has not been specific about which ones he will use.
I previously have seen one of my photos on his laptop as a wallpaper
Today he has posted 7 of my photos (the ones without watermarks) on facebook. Only one has he put my first name only on.
I want to write up a bill for him. I sell my photos in art galleries and Arts & Craft Fairs so I just don't know what to charge for something like this.
Probably won't collect but just for principal will send a bill.
I also reposted each picture on my facebook with PHOTO BY Gerrianne Bielefeldt
Thank You for any help you can give me with this.
