Insure that lightproof lid has been locked into a secure position before turning on the lights. If developing only one roll, load that reel at the bottom of the developing tank and proceed to load an empty reel at the top. Once the film is loaded onto the reels, insert reels onto the agitation rod and into the film developing tank, then proceed to close tank with filler | light-proof lid and cap. The film is loaded onto the reel(s) in the dark. ![]() Set out materials for loading film, including film cassette, bottle-opener, scissors, reels and film developing tank. ![]() Loading Film onto Reel(s) and in Developing Tank Per federal, state and local environmental regulations, you are required to dispose of the fixer in the provided recycling container. With the exception of the fixer, it is environmentally safe to dispose the film developing chemistry down the sink. Clean your clothing and shoes if they come into contact with the chemical. If a spill occurs it is important to contain the spill and notify the instructor and/or lab technician immediately to determine how the spill should be cleaned up. Wash hands after working with chemicals in both the film processing rooms and darkrooms, especially before eating.įilm processing rooms and darkrooms are properly ventilated to insure fresh airflow. No food or drinks should be in the film processing rooms and darkrooms. Get immediate medical attention after washing eye. If you do get chemicals in your eye, wash immediately with cool running water from the nearest source, faucet or eyewash station for 15 minutes. Replace skin oils with a good hand lotion. If you do get chemicals on your skin, wash immediately. If at any point, you get chemicals on you, into your body or there is a chemical spill, it is important to take of the incident immediately, including washing the chemical off, and letting the instructor and/or lab instructor know to assist immediately for the safety of yourself and others in the lab. The goal is to avoid getting chemicals onto and/or into your body.īlue vinyl gloves and safety glasses are to be worn at all times when handling and using photographic chemistry in the film processing rooms. Photographic chemicals should be handled with reasonable care.

The image is there, but it is what is referred to as a latent image. Once the image has been exposed in the camera on film, the photograph has been made, yet nothing shows on film. ![]()
