Always loved these things and have actually seen some .. a bit faded, but
a couple have been lovely (no other word). Pointillist painting and
Autochromes have seemed romantic and so when returning to France a few
years back, I used Fuji 1600 shot @ 1000 to saturate the emulsion,
developed and blew up to 20x24. In thinner areas and certain like there
was an emulation of Autochromes. Have to enlarge to 30x40 I feel to
achieve the effect wished for.
One could also work a soft color emulsion in transparency like Exta 100
or Lumiere and double or triple speed and develop in C41 with a slightly
dilute bath, or shorter development time or with a pnch of citrazinic
acid to inhibit excessive contrast build up. You achieve large grain, no
orange mask, and print it on Portra (Kodak) paper. I've been thinking
recently too, to scan a slide and put each channel into a bit map dither
and combine them to see what happens. Adding noise to each channel might
work too but I think it'd break up into an unwished for spectrum.
