At long last, here are my artichoke images.
Zone VI 8x10, Fuji W 300mm
f90 at 1 or 2 minutes
8x10 and 4x10 negatives
Developed in Ilford PQ Universal Developer
1:9, 70F, 9 minutes in a Jobo 3005 Expert Drum
Lit with one 750W Tota Light w/ umbrella, and large white foamcore reflector
Fairly straight negative scans -- pretty much as I would print them.
I meant the black background to actually be black, but too much light spilled onto it (flowers too close to the backdrop). However, I think it worked out better. Still might re-photograph one of these days.
