In order to make your latent image a negative you must go through a process to make it. You must reel your film and put it in a tank with chemicals in it. These chemicals are called developer and you must leave the developer in for a certain amount of time at a certain temp (68 degrees). You must then poor in a chemical called "stop bath" which neutralizes the chemical process and must be in for 15 seconds.
