Any horror enthusiast knows that there are different kinds of scares. Jump scares, slow-build scares, gory scares, and realistic scares are only the tip of the iceberg when it comes to finding that perfect fear factor.
Photographs are a little different, as you only have a single frame to spook your viewer. Though photoshoped pics tend to be a bit of a cheap scare, photos that are accidentally creepy are definitely worth your time if you're looking to be frightened.
The devil is in the details. Seriously, he's right there. Look closer.
