Default K-14 Process- alternatives?

I have some Kodachrome KP40 that i've shot and am wondering if there
are alternative processes I can use other than sending it to Kodak for
processing using k-14. Perhaps E6?

I don't care too much about the pics but would like to at least get a
somewhat visible image.


Thanks!

Cheers,

If you can get some idea of starting times, you can process K-14 film in
B&W chemisty and obtain a B&W negative with the yellow filter layer
still in place (it's possible to remove the yellow filter layer, also,
but I don't recall how it's done -- it's part of the K-14 process).

Starting time can be roughly determined by putting a piece of leader in
your developer, and timing until (I'm told) it just starts to visibly
darken; develop for 20 times that interval. That should get you
printable images, if you can either print through the yellow layer
(which will act as either fog for graded papers, or a low contrast
filter for VC) or remove it.

Of course not.The K-14 process is VERY complex, and there aren't
alternatives.Why don't send to Kodak?"Film price includes processing".

"Film Price Includes Processing" was discontinued in the United States many
years ago, the Federal Trade Commission deemed it restraint of trade.

One reason why it's always useful to indicate your country of origin in
questions of this sort.

Kodachrome is a complicated beastie, but as OP indicated it can be processed
to some sort of BW image, OTOH I have 400 feet of TMax 400 in my freezer and
see no need to experiment. It might be fun to try, I'm sure there are all
sorts of threads about removing the dye layers in older postings.

You do not want to talk the ignorant operator of your friendly neighborhood
mini-lab (he probably thinks of Kodachrome only as a song his dad sang) into
trying to process it. The older Kodachromes are not emulsion hardened and
melt in the 100 degree F. film processors and the newer ones will deposit
Kodachrome's RemJet backing as black cruddies all over the tanks and racks,
invoking all kinds of colorful vocabulary.

I'd like to keep the color, though.

I'll send it to Kodak. Thanks for the info.

The major difference between K-14 and other color processes (E-6, C-41, RA-4)
is that in all other color films and papers, the couplers which create the
image dye are part of the emulsion (with the exception of Cibachrome). In K-14,
the film emulsion contains no couplers, they are in the cyan, magenta, and
yellow developers.

If you want color images, you can obtain them ONLY with K-14.

Well, the other major difference is that the three emulsions receive
their reversal exposures and color development separately, though this
probably follows from the fact that the dye couplers are in the developers.

What it does do, though, is pretty much guarantee that there will never
be a home K-14 kit the way there have been for E-3, E-4, and E-6 (as
well as C-22 and C-41).

E6, c41,ra4 all of them have half of a dye (coupler), Cibachrome contains
the whole dye, K14 has dyes added during processing (no dye in emulsion prior
to processing)Cibachrome materials processing depends on destruction of the
dye.

OK, why does everyone have to get so picky here. I answered the original
question in a simple matter so as not to overly complicate the issue. K-14 is
complicated enough without trying to explain the process in detail, and I have
seen many misunderstandings about how it works on previous posts on the
subject.

Yes, Cibachrome is different, which is why I made a passing comment that it WAS
different from E-6, C-41, RA-4, etc...I just didn;t want to get into a full
post on how that process worked since it was not related to this subject.

Yes, the coupler in these other processes forms the imaging dye when it reacts
with oxidized color developer. There is NO coupler in Kodachrome films, it is
part of the individual color developer steps and each layer is reversed (2 by
physical light exposure through special filters, and one by a chemical foggant.

No, there will never be a home kit to do K-14 due to the physical demands of
the process; removal of rem jet backing, special reversal re-exposure filters;
plus the fact that the mixed chemicals have a short shelf life, so they need to
be made from scratch within a reasonable time of being used, and cannot sit on
a dealers shelf for months or years.

Bernie;

Your quite right in what you have posted, for thoses that are
interested the K14 process is decscribed in the Focal Press book " LP
Clerc's Photography - Theory & Practice"

Revised 1971 by S. Welford Chapter LI [51] & LVI [56]
