as title says, this is designed to mess up the image in the pursuit of realism. It's intended tol break your whitebalance, add grain, and blur and other organic things Ai avoids usually.
Help it along with some "bad quality, jpg, grain" type prompts.
(depth of field) in the negative helps a LOT for the look
Updated with a v02 that works a bit better. Can even function with minimal prompt help now.
