Originally posted by murrelet I took it to a lab,
Blue Moon Camera. Not sure what they used. But they sell and shoot JCH, so I figure they know how to handle it.
Did they scan it too? 'Cause their scanner might not have been recalibrated for the jch's 'unusual' characteristics (judging by go26r's images and comments, and your own results).
I had a roll of acros 400 dev+scanned by a local lab (TO Image Works), when I picked it up the lab tech told me it had been overexposed by 4-5 stops, and the scans appeared to show that, but the vast majority, shot in hard midday sun, came out fine in PP (I use the same metering for 400 color negs and intentionally overexpose by 1-2 stops):
SP supertak 50/1.4 Acros 400, likely f8|11 1/250 (my default for 400 in direct sunlight)
