Sandy: You'd have to ask Fred Newman, but I'm pretty sure it's blue
channel.. That's interesting about all three of these films come out of
that plant in the Big H. I didn't know that.. -jb

Subject: Re: Test of J&C Classic 200
Jeff,
JandC Classic 200 is manufactured at the same plant in Hungary from
whence also comes Fortepan 400 and Berger BPF 200. I tested it also,
exposing, developing and plotting the film myself, with the 2:2:100
dilution of Pyrocat-HD. JandC Classic 200 is quite similar to BPF but
allows for slightly greater expansion.
I based my testing and BTZS plotting on a desired DR of 1.75 (UV reading
= effective printing DR) for kallitype and palladium printing. At this
DR I got an EFS that varied from 200 at SBR 8 to 320 at SBR 5.5. You can
see partial results of the tests at
http://www.apug.org/site/main/viewtopic.php?t=1579
Regarding your tests, on what did you base the target DR? Visual, Blue,
or UV reading?
Sandy
Dear List: Here are the results of BTZS testing of J&C Classic 200
film. This is exposure and plotting by View Camera Store, processing by
me. The developer is pyro WD2D, standard dilution, in trays. Agitation
for initial 45 seconds, then once every 15 seconds©. The advertised ISO
of this film is (obviously) 200. I just noticed something I hadn't
before now, viz., this film is labeled "Made in Hungary." Does that
tell us anything? Anyhow, moment of silence for Maholy-Nagy (which,
according to M-N's sister, would be pronounced kind of like "ma-HOY
NOOG")©.
