By weird I mean in the engineering since or the word as UNIQUE or proprietary. (My fathers use of the term bored into my head) Way more places process e-3 then ever processed Kodachrome no? E-3 went away when I was 3 soo... But is it different from e-3 . e-3 was just flashed and could be done at home. To do this at home sounds a bit harder. It also sounds like if you process this as standard black and white you are going to have issues as its more similar to Movie film with a super thick anti-halation backing that requires a separate step to remove. So you are going to need that alkaline step as a pre wash.
Kodachrome, and other non-substantive films, required complex processing that could not practicably be carried out by amateurs.[30] The process underwent four significant alterations since its inception.[31] The final version of the process, designated K-14, was introduced in 1974. The process was complex and exacting, requiring technicians with extensive chemistry training and large, complex machinery.
The first step in the process was the removal of the antihalation backing with an alkaline solution and wash. The film was then developed using a developer containing phenidone and hydroquinone, which formed three superimposed negative images, one for each primary color.[31] After the first developer was washed out, the film underwent re-exposure and redevelopment. Re-exposure fogged the silver halides that were not developed in the first developer. A color developer then developed the fogged image, and its exhaustion products reacted with a color coupler to form a dye in the color complementary to the layer's sensitivity. The red-sensitive layer was re-exposed through the base of the film with red light, then redeveloped forming cyan dye. The blue-sensitive layer was re-exposed through the emulsion side of the film with blue light, then redeveloped forming yellow dye. The green-sensitive layer was redeveloped with a developer that chemically fogged it and formed magenta dye.[31] After color development, the metallic silver was converted to silver halide using a bleach solution. The film was then fixed, making these silver halides soluble and leaving only the final dye image. The final steps were to wash the film to remove residual chemicals which might cause deterioration of the dye image, then to dry, cut, and mount the film in slide frames.[31]On Thu, Jul 11, 2013 at 12:27 PM, Jan Faul <jan@xxxxxxxxxxx> wrote:
It’s not a weird flashing process. It’s the same or almost the same as reversing E-3.On Jul 11, 2013, at 11:54 AM, Randy Little wrote:It requires weird light source flashing process I thought which is why there was never mass kodachrome labs.

Maybe some day I'll thaw it and see what happens.
One of the bad parts about not communicating via the spoken word. The tone of a message can't come across....
I was trying for some humor...... 8^)

Buy the lottery ticket in black and white. Kodachrome can now only be processed as B&W as the lab in Parson, KS shut down the Kodachrome processing a good while back.Roy
