Enlarging Film to Produce an Image

Enlarging Film to Produce an Image 

The film can now be used to make contact sheets. I done this by inserting each film strip into the plastic film holder the back- to- front with darkroom paper underneath so that when it was exposed for 15 seconds the images were the right way round and processing the darkroom paper through the chemicals.

I then had to set the enlarger up for making a print out of the film. From my contact sheet I decided on an image to use. I used the air blower to make sure there were no dust or hairs on the film and inserted it onto the enlargers tray. I had to set the paper holder board up to 4.5" x 6.5" to leave half an inch of boarder on the 5x7" darkroom paper. I projected the image onto the blank board and had to set the contrast at 0 for yellow and 180 for magenta and set the aperture. Whilst, looking through the eye piece to find grain on the image to tell me the image is in focus.

Only then could I do a test strip starting at 5 seconds and covering a section exposing it for another 5 seconds and repeating this process till around 20 seconds. I then put it through the darkroom chemicals to see which time was the best exposure time to produce a full size image.
