Diffusion under the enlarger
Bumping this thread. Hope to get some more examples of print interpretations.
Japanese Tea Garden, Seattle Arboretum
The negative looked nice printed straight without diffusion, but didn't quite capture the mood I was after.
Negative: 6x6cm frame on TMY-2 developed in Pyrocat HD
Print: 8x8" on Forte Polywarmtone paper
- Base exposure: Multigrade filter 1.0, 20% without diffusion (sheet of translucent paper [Yupo]), 80% with diffusion material laid over the paper
- Burn exposure: Edges of the print were burned using a card 1/4 stop
- Processing: Developed in Ansco 130, water stop, rapid fixer
- Toning: Selenium toner (1:20) 30 seconds, thorough wash, brief bleach in ferricyanide, toned in thiocarbamide
The degree of diffusion can be controlled several ways: the relative length of exposure with and without the diffusion material; height of the diffusion material relative to the paper; contrast filter used during the portion of the exposure with diffusion. I jiggled the diffusion material during the exposure to create a softer effect.
Are people using other techniques to create diffusion effects? Would love to see examples.
All the best,
