Today I spent time in the lab, learning how to extract film from the cartridges and place them into a “tank” which after some chemical processes leads to developed film. The film is cycled around a reel which holds the film in place while inside a light tight container. Then from cleverly placed openings chemicals are able to get into this container without letting light in and process the film. After a lot of time, cycling chemicals and rinsing with water the film was finally placed into a dryer. I remembered how the process went from some previous experience, though there were some added cogs to the system that I found to be particularly useful, the most being the dryers as when I use to dry film we just left them out to dry up.
Once we got into the dark room, I was shown how to use the easel, how many “ticks” you need to set the lighting for a test strip (4) and how to set up a test strip. After I cut a thin piece from my glossy photo paper, I set it under the light and placed a film strip of 5 photos above it. It was then that I placed a card (a paper card to block the incoming light) over the majority of the film and after 5 seconds I would lower the card to reveal more of the film, exposing the paper to the film and light more each time. After 25 seconds of exposure I developed the paper in chemicals and went back to reveal my photos in 5 different light exposures. The result left me somewhat puzzled as many of the photos exposure resulted in different tones. It was later that I confirmed that it was from when I had taken the photos, over exposing the film to light and taking photos at different exposures that lead to the test strip to show different tones from the 5 second exposures.
It was definitely an eye opening lesson in photography, how light effects everything about the process and the more light the better is never the case. I will have to record my exposures for my photos in order to get the proper timing for light exposure for my glossy paper.
