How to make real negatives

To make nagatives you first have to put the film out of the camera and make it around the reel (in the darkroom!) .Then the reel goes on the center column and both is put into a tank. A cap , which is light proof, is given on the top. Then comes a lid on top that the chemical can't go out anymore.Now you have to shake it around 15 seconds.
You attach chemical developer (68 degree) and later comes the stop bath, which stops the developer.
Now you attach the fixer what makes it permanent. After it follows the water wash or a fixer remover-and ready is the negative!!
