Developing a negative

The developer makes the latent image appear. Time depends on what the temperature is. If it's colder than 68 degrees, you have to wait a few extra minutes but if it's warmer, you wait longer. You take the negative strip and wrap it in the wheel and the leave it in the fixer for about 15 seconds. You rinse it with water for 5 minutes then let it dry.

There's the developer which makes the image appear, the stop bath which stops developing process, the fixer makes image light proof, and the fixer remover rapidly removes fixer.

The tank has a lid that's chemical proof, the cap that's light proof, the center column, and the tank which holds everything together.
