I sold a polaroid to a woman on Facebook. We meet up, chat about film. She’s like yah, yah, yah I have like 5 film cameras. I think wow that’s awesome to find another film friend. A couple nights later she messages me in a panic because she opened the back of her film SLR in light and wanted to know if the photos were ruined. Why don’t people research stuff before doing it? The reason she opened the back of the camera? The film sprockets tore and it got stuck mid rewind. Why did the sprockets tear? (after asking her questions I found out). She didn’t press the film release button at the bottom of the camera before rewinding and tore the film. So she just starts using this piece of equipment willy nilly not even knowing how to use it. When a simple search would have told her those two things. Then I felt like the bearer of bad news telling her the film is ruined.
What kind of cruel person doesn’t immediately say ok got it I will never share your photos publicly. I wouldn’t book her on that premise alone. She’s basically charging you a privacy fee.
Copyright law in the US is the same. But I would need permission from the subjects to share them for the purposes of advertising for my business. Even if I didn’t need to legally I wouldn’t without permission because that’s gross.
