Well that's flipping amazing.

Dorkroom turned me on to Microphen a while ago and it's totally fantastic. I get rich tones, fine grain, and nice push/pull-ability. It looks seriously filthy though in the bottle. There's fogging on whatever it touches, even the funnel that I use to pour the stock solution back in, and there's all kinds of gross black floaters in the bottle. Normal?

The closest to Kodachrome is probably Velvia 50, but it doesn't do white people very well.

Kodachrome just as those beautiful browns and bright whites you just can't find anymore. (That sounded far more racist that I was expecting).


The smallest contact prints I've done are 4x5, and they looked great, but a reckon a bunch of 6x9's in little frames on a wall is a great idea that I might have to steal.

I'm getting this for Xmas BTW:

oh, my, god. Becky, look at her bitrate.
Good luck with that.

Here's how you process your kodachrome:

quote:

Backing removal
An alkaline bath softens the cellulose acetate phthalate binder. A spray wash and buffer removes the rem-jet antihalation backing.
First Developer
All exposed silver halide crystals are developed to metallic silver via a PQ developer. The yellow filter layer becomes opaque because it has a combination of Lippmann emulsion (very tiny grains) and Carey Lea silver (metallic silver particles that are small enough that they are yellow rather than gray.)
Wash
Red light re-exposure through the base
This makes the remaining undeveloped silver halide in the cyan layers developable.
Cyan developer
The solution contains a color developer and a cyan coupler. These are colorless in solution. After the color developer develops the silver, the oxidized developer reacts with the cyan coupler to form cyan dye. The dye is much less soluble than either the developer or the coupler so it stays in the red layer of the film.
Wash
Blue light re-exposure from the top
This makes the remaining undeveloped grains in the blue sensitive layer (the yellow layer) developable. The now opaque yellow filter layers prevents the blue light from exposing the magenta layer (the green sensitive layer, which is also sensitive to blue light). It is important to avoid stray printing light exposing the film base of film.
Yellow developer
Analogous to the cyan developer.
Wash
Magenta developer
This contains a chemical fogging agent that makes all of the remaining undeveloped silver developable. If everything has worked correctly, nearly all of this silver is in the magenta layers. The developer and magenta coupler work just like the cyan and yellow developers to produce magenta dye that is insoluble and stays in the film.
Wash
Conditioner
Prepares the metallic silver for the bleach step.
Bleach
(Iron EDTA) Oxidises the metallic silver to silver halide. The bleach must be aerated. The former ferricyanide bleach did not require aeration and did not require a conditioner.
Fix
Converts the silver halide to soluble compounds which are then dissolved and washed from the film
Wash
Washes the fixer out of the film.
Rinse
Contains a wetting agent to reduce water spots.
Dry
The result is three different color records each with the appropriate dye, just like other color films. The original Kodachrome process in 1935 used dye bleaches and was a far more complex process. Although the formulae have changed over the years, the basic process steps have followed a similar pattern since the introduction of "selective re-exposure" Kodachrome in 1938.

They never published exactly what the dyes and couplers were, but Kodak did publish extensive notes on the process. With some study of the patents and K-Lab manual it's possible to back-create the right chemistry from (expensive) bulk chemicals, if you're really determined. Stephen Frizza did a lot of the heavy lifting a couple years back, though he says it was really frustrating and took about 20 tries to get it right. Even then he says he doesn't think his formulation and process is reliable enough to offer commercially.

You could get in touch with him for some advice; I understand he's pretty open about it.

The really big problem is that chemistry is only half of the game. Getting the re-exposure steps right is a nightmare by all accounts.

I wonder if VSCO has approached that guy in Australia about it. They have to be hitting the bottom of the well by now, they've said the reason they haven't done Kodachrome is because they can't develop the test shots they do to dial in the preset settings.

I was idly musing to myself about Kodachrome today. I forgot about the exposure steps, but in theory that's a solveable problem.

Does anyone know what Dwayne's or any other photo processor did with their K-14 equipment? Or their operating instructions / notes / tall tales?

Dwayne's K-Lab was sold for scrap metal.

Kodak still makes a complete copy of the K-Lab operator's manual available on their website. I've browsed it and have it on my hard disk somewhere. It gives you chemistry times, which is helpful, but no re-exposure times.

If the proper wavelength for the light in the exposure steps was known one could determine the exposure time by doing a micro development lab using one millimeter strips and a gently caress load of time. Of course then you would also have to build a apparatus to do timed exposures.

The guy in Melbourne who did it used to be a Kodak engineer and is apparently quite happy to discuss it with people.

edit: while I'm in here, how bad of an idea is it to double up a strip of 35mm in a Printfile sleeve, long-term? A few rolls gave me an extra frame or two, which sorta plays havoc with keeping everything tidy.

First pair of 14 rolls is washing at the end of E-6 development right now. This process is pretty much exactly as difficult / easy as C-41, which is to say only slightly harder than B&W. Like C-41, E-6 is a process standardized across ISO, so any speed of film can sit in a reel next to any other speed of film in the tank for the same times.

I'm using the Tetenal kit, which suggests my mixed chems will be good for a few weeks as long as the lids are tight. So far, so good.

The "agitate every 15 seconds" schedule is brutal, though - 10 seconds is not enough time to do anything, but too long to just sit and stare at the wall.

EDIT: I like developing slide film. Pretty colours!
