Step by step to great colour: Load a Lomo or Holga with Kodak's Ektar 100 print film. Take a bunch of shots. Throw the camera in the glove box. Leave it there over a +35 C (100 F) week. Take the camera out and put it in a backpack, put the backpack in the trunk. Leave it in the trunk over the winter (-25C/-13F). Take the backpack out, curse at yourself for leaving the camera in there. Get the film developed. Argue with the lab that they screwed up, wind up with a credit on your account with the lab. Realize what you did but still enter some of the pictures in the local camera competition. Argue incessantly that you did not fake it in Photoshop.
