I was contacted a few weeks ago by a woman and her friend who said they want to create a "Lunisolar" calendar featuring local Colorado artists and they wanted to know if I would send them high-res versions of some of my moon pictures (since the ones on my site are max. 10" at 72 dpi in an effort to prevent commercial use without asking me). I replied asking if the calendars were being sold or given away as some sort of charity thing since obviously if people are making money off of my work I want a piece of the pie, so to speak. She replied this week with: So I'm curious to know what you guys think. Should I say "what the heck" and just give them what they want with the assumption they're honest and may give me 2.5% or whatever of their profits? Or should I be fickle about this and request some sort of contract, etc.? Or should I ask for more information (considering the sample month she sent me didn't open ... some sort of PDF error)? Advice is appreciated.
