Q: processing Kodachrome 25 color slide to get B&W?
You can process Kodachrome at home as a color film, but not likely with
success, roll after roll. It requires extremely precise time and temperature control because it only works if the developer diffuses a very precise distance into the emulsion, and no farther, before it is neutralized, and it must do this three separate times. I suspect making a rocket would be a lot easier. David Foy By the way, did you know Kodachrome was invented by two musicians? "Alec Jones" wrote in message .. . Simply NOT true. Just read the continued thread below. There have been several people in the past that did it at home, and without the automation you presume. It is difficult, but not "rocket science". So, do some research before you just spout off such absolutes! "Randall Ainsworth" wrote in message ... I think that would depend upon the size of one's home and wallet! There's always a way, or it couldn't be done anywhere else. No, the machinery is extremely expensive and it requires several highly trained people to run it. YOU CANNOT PROCESS KODACHROME AT HOME!!! |

It requires extremely precise time and temperature control because it only works if the developer diffuses a very precise distance into the emulsion, That was the earlier Kodachrome color development process. Probably just in the 1930s. The later process was a conventional color coupling development and was a great improvement in many areas. and no farther, before it is neutralized, and it must do this three separate times. I suspect making a rocket would be a lot easier. I have to express admiration for both. Processing Kodachrome preceded the moon landings, so, perhaps Rocket Science is somewhat harder. ;-/ David Foy By the way, did you know Kodachrome was invented by two musicians?

I suspect making a rocket would be a lot easier. The original Kodachrome introduced in 1935 relyed on diffusion control. The film had fat interlayers between the color layers to allow for some variation. Process control technicians routinely used a microtome to cut crossections of the filme to view under a microscope. In 1938 Kodak introduced the "selective re-exsposure" process. In this process, there were red and blue re-exposure lights to make these layers developable prior to the separate cyan and yellow developers. The magenta developer (last one) had a chemical fogging agent. The re-exposure lights would be the tough parts of the process to do at home. It is not impossible, but it is well beyond the capability of the typical home darkroom enthusiast. You would also need to find a source for the raw chemicals and mix your own solutions.

I doubt if you could find the chemicals to do K-14 processing at home. They
are exotic and expensive, and they are made for machine processing. You also need a way to re-expose the film to the right colored light in the reversal process and a way to remove the rem-jet backing from the film. Commercial labs will still process K25. It uses the same process as K64. "David Foy" wrote in message news:x14eb.24141$o21.342@edtnps84... You can process Kodachrome at home as a color film, but not likely with success, roll after roll.

Fascinating! I much appreciate your contribution.

I agree. Those among us who might do it are also those who could source some
fairly exotic chemistry. DF "Norman Worth" wrote in message hlink.net... I doubt if you could find the chemicals to do K-14 processing at home.

It's my understanding that the processing machine is about 80 feet long for
one thing...try explaining that to your wife. Also, I'm told the QC manual is about 5 inches thick...sounds like K-25 processing needs to left to the pros... "David Foy" wrote in message ... I agree.
