I wanted to slap the taste out of my best friend's mouth (not really, but kinda. You know?), so I took a photo of him instead.
The trick was to have him press his face against a piece of glass from a picture frame to make it look like he got slapped for real.
Next I developed the negatives, and exposed a piece of photosensitive paper with the image in a dark room. Instead of putting it in the developer, I dipped my hand in and slapped the page. This is not something you should make a habit of, as the chemicals are not exactly healthful, but it came out pretty cool, so I’m okay with it.
This is a one of a kind, each slap is different!
