Black-and-white film development is the process of converting the latent image on a film negative into a visible image by exposing the negative to various chemical solutions.

To develop black-and-white film and make prints in your own custom darkroom, you will need the following materials:

*   Black-and-white film
*   Film development tank or reel
*   Developing chemicals (developer, stop bath, fixer)
*   Darkroom enlarger
*   Photographic paper
*   Trays for chemical solutions
*   Safe light
*   Tongs

Here is a step-by-step guide to the process:

1.  Load the film onto a reel and place it in a development tank.
2.  Prepare the developer solution according to the manufacturer's instructions and pour it into the tank. Agitate the tank for the recommended amount of time.
3.  Pour out the developer solution and pour in the stop bath to halt the development process. Agitate the tank for the recommended amount of time.
4.  Pour out the stop bath and pour in the fixer solution to permanently fix the image. Agitate the tank for the recommended amount of time.
5.  Remove the film from the tank and hang it to dry.
6.  Load the film into the enlarger and project the image onto photographic paper in a darkroom.
7.  Prepare the developer, stop bath, and fixer solutions as before, and use them to develop the photographic paper in trays.
8.  Hang the prints to dry.

It is important to note that developing film and making prints in a darkroom requires careful attention to detail and precise measurements of chemicals and exposure times. Proper safety precautions should also be taken when handling chemicals.
