I live in a popular tourism county and a local visitor's center for one of the towns is interested in using some of my photos. They asked me what I normally charge for usage. I'm not sure as I am new to this. This is what they said was pretty standard. Typically for use on their website or Facebook page, photographers usually only ask for photo credit. For use in their guidebook, they offered $300 for the cover and $25 each for any inner photos. I know local markets may vary but does this seem relatively fair to you? Thanks for your input.
