Experiment - LUMEN
Updated: Jan 20, 2022

Paper used for the experiment:
ILFORD MGIV MULTIGRADE IV RC DE LUXE
Colour : Pearl
I assembled the picture in the darkroom under red light, and I exposed it to UV lights at 11:01. It was a sunny day in London, but also October, so the sun is not as strong as it would have been in the summer. I did my first check at 11:11 and the paper started to change its colour, meaning that the sunlight was processing the paper. My second check was at 11:25, but I was not pleased with the contrast, so I left it outside for more time. At 11:57 I decided to end the exposure, and I brought it into the darkroom to process it.
Exposure time: 56 minutes
Darkroom process:
stop: 30 seconds
fix : 3 minutes
wash: 20 minutes
NO DEVELOPER USED

Exposure time: 1 hour 3 minutes
Darkroom process:
developer: 1 minute
stop: 30 seconds
fix : 3 minutes
wash: 20 minutes
DEVELOPER WAS USED
CONCLUSIONS:
Using developer darkened the paper, and gave a less contrastant effect. Where the sunlight touched the paper, even a little bit, it made those parts black, and just where no sunlight has reached the paper was white.
In the first experiment, where I did not used developer, I got a bigger contrast and the flowers came out in more detail.
Comparing the two experiments, the one without the developer gave a much wider range of shades of grey, and it even shows some pinkish-brownish shades. The developer darkened the paper, and absorbed many shades, leaving just a few shadows.
