Search through stock photography sites like 123RF, Shutterstock or Getty Images and you'll see lots of cheesy staged photos starring generic looking people pretending to do stuff.
You'll also see lots of different color palettes, people and places from all around the world and photos shot perfectly using the rule of thirds.
But who needs all that when you've got photos of a kid crying while holding a gun, drunk drivers toasting as they're about to run over some kids and a pic of a shirtless guy dumping a handicapped person into the pool?
I'm not sure what you can do with these extremely dark stock photos besides laugh at them. On the other hand a picture of a granny with a gun and a look on her face like she's ready to bust a cap in someone's butt is definitely worth buying!
