NO food or drink to be taken into the darkroom.
Keep tidy: put bags and coats in the cupboards under the enlargers so you can’t trip over them in the dark.
Keep wet items away from the dry areas of the darkroom.
The chemicals are harsh irritants: if you ingest them or get them in your eyes, speak to a member of staff as you may need medical attention.
There are disposable aprons and gloves to wear for your protection. Wash your hands after you come into contact with the chemicals.
To make a contact sheet of your negatives using the print processor
You will need to use a contact sheet printer.
Set up the enlarger:
Undo the locks before using the handles to adjust the lens and the head of the enlarger.
Switch on the control panel, the switch on the focus light to move the enlarger head to the right height to cover the contact sheet printer with light. When this is done, re-lock the handles.
Fully open the aperture on the lens.
Switch off the focus light.
Cut one sheet of your paper into strips with the guillotine. Do not tear them. The strips must be at least 8x2 inches big.
Load one strip of the negatives in to a slot in the contact sheet printer. The shiny side of the neg should be next to the glass, so the film’s emulsion will be in contact the paper.
Put one strip of paper under the negative, ‘shiny’ side up. This is the side containing the light-sensitive emulsion. Close the printer.
Make a test strip using a piece of black card. This is the simple method:
Set the control panel to grade 3. Set the seconds to 5.
Press the expose button on the enlarger panel to give an overall exposure of 5 seconds.
Cover a small area with the card (try not to line the card up with the end of a frame as it will be easier to judge when the test strip is processed).
· Press the expose button again. This will give another exposure of 5 seconds to any uncovered paper, making a total of 10 seconds.
· Continue until you have completely covered the paper.
Insert the paper emulsion-side down into the print processor.
When the test strip is processed, pick the best exposure.
Set this on the timer on the control panel.
Load all the negatives in to the contact sheet printer.
Place one full sheet of paper, shiny-side up, into the contact printer and make the exposure.
Insert the paper into the processor as before.
