Excerpt from the User Guide from Digital Truth:
"Most of these times are for condenser enlargers, so if you are using a diffused light source it is advisable to develop for additional time."
Just about every time I cross reference developing times to another source, they are virtually always times for diffusion enlargers. I know all Kodak's and Ilford's recommended times on film/developer data sheets are based on diffusion machines. Agfa's recommended times are for a contrast index of 0.65, hefty even for a diffusion machine. Kodak's times are for CI 0.58 for diffusion enlargers. Kodak recommends [I]reducing[I] developing times by 20-30% for condenser enlargers.
Seems we recommend this chart as the 'Gold Standard' for starting times.
I have yet to pull a time from the DT Index that has correlated with a condenser enlarger's (CI 0.42-0.43) recommended times.
What gives? Am I missing something here? Maybe this is why we have so many threads about 'overdeveloped/blocked highlight' film?
