There are many debates about ethics in photography. One such debate is around making money on photos that show human suffering. It could be appropriate, but there are a few caveats you should consider before selling such work.
Photographer and YouTuber George Muncey of Negative Feedback recently set out on an ill-fated adventure in film scanning. He went out and bought the cheapest 35mm film scanner he could find online—the DIGITNOW! 135, which costs a whopping $60 on Amazon—and tried it out so that you don't have to.
From time to time when I read about Street Photography, I hear the opinion that street photographers exploit people on the street by taking their picture without asking.

When photojournalists capture images of human suffering around the world, they're often accused of being coldhearted and of exploiting those in need. The media organizations and charities that send them out draw similar criticism, but they argue that these negative stories help bring attention to issues that would otherwise be ignored and that they help encourage charitable giving.
