I just recently shot a roll of Kodak's Black & White +400 and turned it in to
Kodak Premium Processing (KPP) for next-day developing and printing (just as
you would with C-41 color negative). This is a chromogenic C-41 process film
that has replaced the consumer version of T400 CN and is similar to the Ilford.
Now for the truly amazing part. When I went back to pick it up a day and a
half later it was not there. Upon inquiry I discovered KPP shunted the film
off to their B&W lab for processing in another state. They tried to give me a
song and dance routine about how it is B&W and takes *five* days and can not
only be processed C-41 but put through their B&W process also. Baloney! Not
unless Kodak knows something unpublished in their data sheet on the film which
*clearly* states process C-41 *only* and *not* to use standard B&W chemistry.
I am wondering if anyone else has suffered this problem at the hands of KPP?
This completely defeats the whole point of using a chromogenic C-41 B&W film
that has shorter archival life (about 20 years; similar to color negative) and
takes the same processing time (5 days) as Plus-X, Tri-X and similar films!
BTW . . . the tech data sheet on this shows different response curves than for
T400 CN's. It is more blue sensitive and not as flat across the spectrum. I
had to ask Kodak where the tech data for 35mm B&W +400 is on their site. The
Advantix tech data sheet on B&W +400 is missing the response curves along with
a few other tidbits. They sent me a URL I cannot find a path to from the main
page. The tech data on T400 CN is found going through their B&W professional
film listings.

If it wraps on the end of line make sure you copy the *whole* thing (without
