Dark, Darkroom

You will need to prepare a dark space where you can unload and develop the 4x5 film. Find a small room (it is best that this room has a wide, flat sink or have a long tub available to limit spilling onto surfaces) and line the door with black tape and a curtain to block the light. If there is a window, cut out cardboard or dense black foam core and tape it to the window. Check the light level of your darkroom before proceeding, if you see light coming in block it with tape and cardboard.

Setting up Chemistry

You will need at least five (5) trays that are 5x8 inches in size. You will need 500ml of water, developer, stop, fixer, and fix remover. Use your thermometer to test the current temp of the chemistry and memorize the time for the development that session.

Layout

Before turning the lights off, arrange the trays (in any prefered order, try to keep it linear) from left to right as follows: Prewet tray (water), Developer tray, Stop tray, Fixer tray, Fix Remover tray. Have your film holders in a dry place nearby, so when you turn out the lights you can unload the film easily and place it in the prewet bath.
