Kodak K-14 Process

Hello 435,

Kodachrome film is supplied in three ASA's-25,64,200. Characteristics of

film-Outstanding grain and sharpness,vivid color,natural skin tones. Try

some 25 ASA sometime! You'll be impressed! I think kodachrome may be

my favorite color film. I do not like Fuji greens. Film is processed in K-14

Lab Processor. Dryer Tank is at temp. of 105F. A chiller system in the pro-

cessor achieves temperature specifications inside the developer tanks. Water

is mixed between 85F and 100F for processor use,this is done via intellifaucet

connections. Process:

1. First Developer And Wash

2. Cyan Developer And Wash

3. Yellow Developer And Wash

4. Magenta Developer And Wash

5. Conditioner And Bleach

6. Fix,Wash,Final Rinse

If you get a chance photograph a beautiful movie star with Kodachrome 25,

use flash. Make sure you ask her for permission to photograph her! Always

ask for permission and you will develop a reputation.

Hello 435,

E-6 process is simple for still film, any good photography book will

explain how to do it,chemical process etc..You can actually develop

film at home and mount slides yourself. One question though are you

talking about movie reversal film or still film? Movie reversal film is

different and must be sent to labs that perform the service. Kodak has

listing on this subject on their web site. Kodak has formulation of chem-

icals on their website for K-14,E-6 a little hard to find but its there. E-6

can be done at home easily. K-14 is different animal,rigid control needed.

Hello Again 435,

I forgot to tell you that Kodak has darkroom manuals for chemicals

and processing of film. Contact them on website and inquire how to

obtain. If you are interested in the chemicals you'll need a manual.

Maybe Mr. Pytlak will be on our forum(Kodak) and will reply. He's on

forum a lot. Best regards. If you have difficulty finding info get back

to me and I'll help you find.

Many years ago Kodak maintained a monopoly on processing Kodachrome. Then the courts ruled that they had to release the formulas to the commercial labs. So they did. As far as I know, a few tried to run the process for a while and then gave up as it was so complex.


It's a different type of process from Ektachrome, in that the dyes are added from the developer, rather than being in the emulsion in the first place. That allows them to use different dyes, which is why it's such a superb stock: but it's clearly too hard for the average home darkroom. Quality doesn't come easily!

Hello 435,

Here is process for E-6 which you can do at home unlike K-14. Process

as follows:

1. Pre-wet film in tank,no agitation.

2. First Developer,agitate first 15 sec. then for 5 sec.

every 30 sec..

3. Water wash and change water frequently

4. Color developer,agitate first 15 sec. then 5 sec. every

30 sec..

5. Water wash for 1min. 30 sec. and change water frequently

6. Bleach/fix,agitate first 15 sec. then 5 sec. every 30 sec.

7. Water wash and exchange water frequently

8. Stabilizer, agitate first 15 sec. only

9. Dry film, time will vary due to where you hang film to dry.

For this process at home you can use tank&reel,manual or motorized agitation,

table top processor(expensive). Tank & reel will do you well and agitation is not

hard at all,you get practiced with it. One problem you may see is that you will

have in-consistant color and tone through out roll of film with improper agitation.

As a young photographer I processed many rolls of ektachrome in my darkroom.

You can buy E-6 kit at photo supply stores. I did not give times and temp. for each

step due your kit will tell you that. Greg

If you have no darkroom experience you may want to learn to work

with b&w film first in the darkroom. This will get you used to agitation

method,washing,drying film. Transfering film from its own roll unto the

tank reel for development, is a little hard first time around in the dark.

If you have a friend who does darkroom work or know a photographer

who will help you,that would be a good start. You do not need to buy a

whole lot of expensive equipment if you are on a budget. Of course once

the film is sealed in the tank you can turn the light on. Temperature may

be maintained by keeping chemicals in their bottles in a plastic tub along

with development tank. Aquarium heaters or photographic heater(sold by

photo stores may be used). It really is a thrill the first time to hang a roll

of ektachrome up to dry and look at your images. I do not know anymore

what is available to mount slides but you can get paper or plastic slide

frames and devices are available to cut and mount them. Of course you

can practice telling a story with slides/slide film. All of Kodak's darkroom

manuals are excellent. If you are going to do any T-Max let me know and

I will save you a lot of headaches! With most of the E-6 kits you can use

solutions at various temps. from about 75F to 110F. Best regards!

If anyone is wondering about why Kodachrome cannot be processed at

home,will discuss as follows: Its usually processed in a Kodak K-14 Lab

Processor. Kodachrome has 3 light sensitive layers,each containing sep-

erate b&w emulsions with different color sensitivities. The top layer is sen-

sitive to blue light,the middle layer to green and the bottom layer to red.

There is also a yellow layer positioned below the blue to keep blue light

from effecting bottom layers. After the film is processed the yellow filter

layer disappears. Each b&w layer(emulsion) records light in proportion to

the original colors of the subject. The blue sensitive layer,for example,re-

ceives the most exposure from blue parts of the subject. In the first dev-

eloping stage ,the film turns in to the equivalent of three different b&w neg-

atives,with silver density deposited on each layer according to the amount

of exposure each area of that layer has received. A blue jacket for example

will record with greatest density on the film's blue layer. The second develop-

ment reverses the image to create a positive and introduces dye in each layer

according to that layer's sensitivity(original exposure). The dyes form the Im-

age color. The film is then bleached and fixed. Thus Kodak K-14 Lab Process-

or is required. I send my kodachrome to Philadelphia and it takes me 3 to 4

days to get my slides back. Greg

The K-Lab guide to processing KODAK KODACHROME films in the K-14 process:






(NOT easy to do at home)


And only a handful of labs left in the world:




Here is the much simpler E-6 process for KODAK EKTACHROME films:

Thanks all, My question was about formula of developer

not all the developing process.

I've enough darkroom experience, even more than enough.

Im cooking developers and fixers in our lab (in VGIK)


last year we spoke about this process and people told nobody knows how to cooke developer for it. I told may be its secret but may be not ?

thats why im asking here


which and how much chemicals inside of this developer ?



second question is new :)

where can i see expamles of this process (I mean photos)

which latitude had or still have this positives? (gamma, gradient, Dmin Dmax and most interesting color curves)


thanks again...

Many motion picture labs mix their own solutions, and the formulae are published by Kodak:




Premixed "Kit" chemicals are also available, and used by labs that don't have a staff chemist or analytical capability:




The on-line Kodak processing manuals and film technical data often show the effect of processing variations:

Are we talkin about K-14 ?

because I coulnt find there. its all about motion picture processing...


I think Kodak didnt published formula of K-14 developer.


I believe the chemicals were available as pre-packaged "kits":
