I have already shot and processed the film. I am picking up the lab roll this afternoon. Tomorrow I will read the densities and begin printing and scanning for evaluation. I included a Macbeth color checker in the shot, so I have reference colors and gray patches, as well as a gray card and skin tone (my hands). On first impressions, the 68 roll has lower density despite careful temperature control, agitation, and development time. The 77 and 100 look identical in density, but I cannot judge the color balance until I either print, scan, or read it on a densitometer. I'll post the results as soon as I have them.
