I've known for the last five or six years about the two unexposed rolls of 35mm Kodak Tech Pan idling in my freezer, but I've been waiting for the right situation to shoot them. (Seeing as the film's been out of production since '04.) Well, last week way in the back, lodged between the frogs' legs and the catfish, I discovered five more rolls. So I'm sitting on seven of these virgins (not literally), and I'm anxious to shoot Tech Pan again. Unfortunately, I understand that Kodak no longer makes Technidol, which was the recommended developer.
Does anyone know of a substitute? I would be requesting this from a commercial processor as I don't do my own developing.
Also, should I forget about getting the same results as back in the good old days?
Thanks.

I'm in Tokyo and would prefer to process locally. But if they use a different developer and I don't get the old "Technidol results", I'd be willing to use Rocky Mountain. We've got a real favorable exchange rate right now, so it wouldn't be too pricey.
I'll ask around at a couple of the pro shops and see what I can do. Thanks for the tip.

Tech-pan comes out not-too-terribly-badly if processed in color negative developer. Do not run the film through a CN line, though, as the bleach step will remove the image from the film. See if your local pro shop can run it through color developer, remove it from the CN line, and then process as B&W. Developing Tech Pan as color negative used to be the standard commercial process in the US.

The best results are still obtained with Technidol. Photographers' Formulary makes a Tech Pan developer but I haven't tried it, reports I have heard are mixed.
 
Thanks, but what's a "CN line"? I'm going to have to translate it into Japanese for the local boys to understand.

You'll need to tell them to develop it in color developer but take it out after that, don't do the bleach step or it will give you blank film! I don't know how many machines will let you take a film out partway but that's what you have to do.

My Japanese is getting rusty but perhaps this will contain a useful word or two:
自動フィルム現像機で漂白剤のステップの前にフィルムを取り出してください。次に黒白フィルムのフィクサーのステップをしてください。

CN = Color Negative
line = process, manufacturing flow

A "CN line" is whatever/however a laboratory processes color film. It can be a 35mm tank and a few bottles on a bench, a Jobo, a dip & dunk machine, a mini-lab or a maxi-lab.

A lab would also have a black&white line and an E-6 (color slide) line.
 
I recently developed a roll of Tech Pan in Rodinal 1+100 9 minutes. Came out just fine. Three turns a minute.

There was a procedure published for Rodinal by a photographer in Photo Techniques magazine just before the Athens Olympics. Worked fine for me

Dear mitya138,

I use c-41 developer for 8-1/2 minutes in a Jobo style processor. 10 minutes for hand processing (Agitate for 30 seconds then 5 seconds every 30 seconds.) Exposure at box speed.

Good luck with whatever you decide,

I have not shot Tech Pan in a long while but the last time I did I was out of Technidol so I used T-Max developer and it was fine.

I've been very pleased using it in D 76

Technical Pan Development (68 Degrees)
Pre Soak 5:00
D 76 Developer 9:10
Stopbath :30
Fix 7:10
Tank Rinse :30
Cycle Freshwater x6
Photoflo :30
 
"D 76 Developer 9:10"

D76 1:1?

Thanks.
 
 
Thanks Tom.

I believe Tech Pan in D76 will yield continuous tone but high contrast images. For regular contrast and continuous tone, technidol is the default answer. Rodinal, HC-110, and PMK in high dilutions are recommended. Diafine is frequently mentioned too but I don't know if the contrast is in normal range.
 
image attached: exposed 100 iso. pre-rinse 6 min. Development 6 min continous agitation. Neofin doku.

Not high contrast, but fantastic for skin tones.

Cropped 135mm film.

The images are great. Anyone has MSDS for Tetenal Neofin doku? I googled and cannot find it other than the Neofin Blue MSDS:
Metol ........................... < 1%
Hydroquinone ................ < 1%
Potassium carbonate ...... 5 - 10%

I don't know what MSDS is, but I'll take a look at the bottles to see what I can find..

What I do know is, that Neofin Doku is very different than Neofin Blue (or Red)

EDIT: sorry - no such info on the bottles or pack or instruction sheets.
