To all photographers, Panchromatic film

[Greg12]

Panchromatic film is developed by Process C-41 or E-6?

I bought some infrared film and it said "INF-24" I don't think that's a process but the instructions say it can be developed with panchromatic film. I think this is E-6 but i'm not sure.

The film in question is Konica Infrared 750 black and white film.

Developer:
The same developers that are used for processing panchromatic films can be used with Konica Infrared 750 film. Final contrast of the film can be adjusted by changing the standard development time. A Small tank can be used to process the film. The following table illustrates the standard development times for different developers. When processing, it is important to agitate continuously for the first minute and then for 5 seconds at one minute intervals until the development step is completed.

DEVELOPER TIME (25°C)
D-76 6
DK-20 7
ID-68 6


Stopbath:
Use a 1½% acetic acid solution of stopbath. Immerse film in the stopbath for 30 seconds with the temperature about the same as that of the developer.

Fix:
Use the Konica fixers or equivalents described in the following table. The fixer temperature should be about the same as the developer temperature. During the fixing step, agitate the film for 5 seconds at one minute intervals.

FIXER TIME
Konica Fixer (acid hardening) 10 min.
Konica fix rapid (acid hardening) 3 min.


Wash: Wash film in running water @75°F/25°C for 20-30 minutes. To reduce water wash time, dip the film into a 2% anhydride sodium sulfite solution for 2-3 minutes after fixing. Place under running water with agitation for 5 minutes.

Dry: After washing, dip the film into a ½ solution of wetting agent for 1 minute. Hang the film in a well-ventilated and dust free location. If a wetting agent is not available, gently squeegee the water off the surface of the film with a sponge.

hope you used a red (Kenko R-1) or orange (Kenko YA3) filter when you exposed it ... or you will get nasty results

I got a paper with all that but i need to know what process number it is?

I work with different labs for different processess.

exactly -- as you can read above its not the same proccessing as c-41 or E6 --- its proccessed as Motion Picture Film type 15

[Greg12]

crap, i wonder wha will happen if i C-41 it. I don't know how to process that film.

[VS]

for starters, if you process that film with C-41 chemistry you run the chance of completely removing the emulsion from the film. Meaning that your roll would come out with absolutely nothing on it - not even frame numbers (assuming it has frame numbers like 35mm, 120, etc).

I've worked at a photoloab for over 5 years but I am not an expert. I've processed c-41 (standard color negative type film), E-6 (standard for most slide films) and traditional black and white film. I have seen IR film that should be processed using traditional black and white film chemistry, and if that's what your film is both C-41 and E-6 chemistry would destroy any images that were on it. I've seen this happen first hand - you don't want to accidentally mis-process your film...

You said you work with different labs for different processes, have you called any of these labs to ask them about your film? I have no formal training in the chemicals and whatnot, just what I need to know to do my job and my boss has been doing this stuff since he was in the military in the late 50's. I assume you tried google also?

According to that page there, I would bet your film needs to be processed in what I call traditional black and white chemistry. If you know a lab that can process kodak t-max film, then ask them about your film. I could be wrong, just trying to help... that line about "what if" and C-41 is a big no-no if it's B/W film, man!

inf-24 probably stands for infrared, 24 exposures... nothing to do with chemistry.

Panchromatic normally refers to film that is sensitive to all colors, and normally refers to B/W film, as color films are already panchomatic and don't need to be labeled as such. This also suggests that there are B/W films that are not sensitive to all colors, which is true. You should be able to get the info you need from the manufacturer, or the retailer. If your retailer doesn't know the process it uses, time to find another retailer.

If their is a photo curriculum at your school, walk on down and ask the professor about it, I bet that at least one person would know.

This has all the details you need (from the Konica website):

The film really should have had this basic information in the box when you bought it. Most films that have special purpose like this normally do include basic developing suggestions, as well as basic exposure suggestions.

[lordsmurf]

Check the box. Most film comes with an instruction sheet.

Don't develop true B&W film in C-41 or E-6, especially not infrared.

And if you develop this yourself, remember to be 100% in the dark at all times with it!

Konica film isn't great, I would've used Kodak IR.

[Greg12]

My C-41 lab wants to try it in there machine, they can process Kodak T but that is C-41 black and white.

I think i will send it into safeway with instructions "process standard bw"

Thank you for your help. I looked at all the techincal manuals and such but i was never able to find a process number, just a bunch of info on chemicals. I don't develop my own film so the process number is important for me.

Somewhere i was told it was Process AR-6 and i only found 3 labs able to do it, and they all wanted 30 dollars plus a 3 month wait.

We don't offer photography at our school anymore, we are going to soon but the teacher doesn't know what process this film is.

Kodak Infrared was to much money, I work for an in-debt school yearbook and i had to back this with my own money cause they thought it was to risky and unnessisary.

[BJ_M]

its not a proccess number afaik - its the same as for motion picture film ..

i can tell you where we get ours done -- but they will not do only one roll ...

[The village idiot]

Here is a data sheet on the Kodak D-76 developer, it is a standard B/W film process, there should be a few place that can develop it for you.

[The village idiot]

If you are worried, print out the Konica data sheet, and bring it with you. That way the lab has the directions, and hopefully can't screw it up!

if he is sending it to safeway for proccessing -- i bet they can screw it up !

you know the type of proccessing they would use/have there ....

[lordsmurf]

$30 for IR development isn't too bad actually, but the 3-month wait time is a bit ridiculous.

Where are you?

I've done photo work in quite a few locations...

[Greg12]

Im in PG county MD.

Safeway says it can do regular black and white.

Oh dear God, no! NO!!!!!!! Not Safeway!

I have no idea what PG means, and can only guess MD is Maryland. I know things around the DC area and surrounding states, but I don't recall county names, barely even remember city names.

If you give your city, state, zip I can help.

[Greg12]

I live in Prince George's County MD, in the southern part, Upper Marlboro, not far from Bowie or Waldorf.

What's the zip code? That's actually the most important thing I needed to know. I have access to photo searches and photographer directories, all which could lead me to a good place for developing.

[Greg12]

Safeway returned it, they said they don't offer that kind of developing

[lordsmurf]

See what this place offers: http://www.customtouchcolorlab.com/
Or this one: http://www.bwcolor.com

If they don't, surely they'll know who else can...

[Greg12]

i emailed both studios


is there a special directory u used to find these

[lordsmurf]

I searched yahoo yellow pages.
I also e-mailed a photographer I know from around there.

Those are the responses I got.
