Second "production" DCG hologram. The first one didn't come out, the subject was too squishy, and moved during the exposure. Note the shadow on the lower right side, the subject moved slightly.
20% 250 bloom gelatin
mold coated with scotch tape shims (2 mils)
dried about 5 days (mostly because I had to go to work...)
sensitized for 1 minute in a 3% solution of K dichromate, rinsed in 1/2 % K dichromate to avoid crystallization.
dried overnight, it was about 12 hours old when exposed.
exposed for 200 seconds, to 100 uW/cm^2 457nm light
So about 14 millijoules/cm^2 (angled at 45 degrees)
washed for 30 seconds in distilled water (picked up lots of dichromate)
fixed for 30 seconds in 1 % K metabisulfate, no hardener
swelled in distilled water at 26C for 5 minutes
2 minutes in 70% IPA (26C)
2 minutes in 91% IPA (28C)
2 minutes in 99% IPA (28C)
