JandC Pro 100 clearing issues blue cast...

[scootermm]

got a quick question and wondering if anyone else has any advice.
I opened a batch of recently bought JandC pro 100 8x10 film. I shot it as usually and got some wonderful negatives. Although in the fixer the blue cast isnt clearing from the film. I usually shot Ultrafine 125 in 8x10 and it was a pinkish cast then gets cleared in the fixer.
The blueish turquiose coloring still seems apparent in the film even after fixing and a good long wash.
any suggestions or is this just the coloring of the base and nothing to worry about. Ive this film before in 4x5 but didnt notice this.

I'm not 100% sure but isn't the j&c the same as the efke 100? If so, did you give it a presoak. I have done that with the efke and I haven't had that problem. I believe that they recommend a 1 minute prewash.

cast?

Doesn't J+C's website have a reference to this as a new batch of the 100 film? Best to ask them. So you have been having good results with this film?
I have posted here several times trying to get some feedback on the pro100.
The box of 4x5 I had was defective. (old run)This film has good tonality;reminding me of Verichrome Pan. So please do all of us a favor and report back on the thread about the blue stuff and overall useage. Much appreciated....
Best, Peter

I've not had a problem with the color clearing from the J&C Pro 100 in sheet film sizes. I use the fix from Fine Art Photo Supply...it's an alkaline fix that has done a wonderful job for me with clearing the hard-to-clear films (especially the eastern European films that always had pink or purple cast before I started using this fix). The fix is now called "ArtFix"...you can find it on their site at www.fineartphotosupply.com.

G - J&C Pro 100 is not Efke...it's a film that J&C has coated for them in China and then cut in Europe. It's their own film and it's not sold under other names. They're very different films, although they're both very nice and I use them both.

Peter - I love this film. Until it came along, I was using only Efke in 100 speed sheet film. This film isn't better or worse than Efke, just different...and a whole bunch less expensive. This film builds density amazingly well, and is great for enlargement or alternative processes. I've had great results with it using Rodinal and Pyrocat-HD. There have been reports of pinholes in the emulsion if you use stop bath...I've always used water for stopping the development and the ArtFix alkaline fix and have never had a single emulsion problem. I can't actually tell you how much of the film I've used, other than to say it's "a lot."

In 120 size the backing paper isn't the best (the lack of real tape at the end of the roll is no help), but since J&C started providing a plastic container for the film with each roll, light leaks haven't been a problem in 120 with this film.

All-in-all, it's pretty amazing that film this good is available so inexpensively. I'm thrilled with it, and shoot an awful lot of it in 120, 4x5 and 8x10.

Forgot to mention: I do always do a 2 minute pre-soak with all of my film...this might be helping remove the antihalation layer.

Pro100

Mongo-thank you very much. That's the response I was looking for. I'm just picking up my 8x10 again and this film is a viable alternative. Everything else is getting very expensive. Regardless I'm glad to know that the film does work. The fixer that you mentioned from fineartsphotosupply is very good indeed. I have used this for over a year now and it works superbly for the staining developers. I'm really suprised that more people haven't picked up on this. I sent Tom Hoskinson a package and there is a very in depth review ala Tom's great way of researching things right here in the APUG archives.
Thanks again,Peter

Glad I could help Peter. If it's any indication of what I think of this film, I have eight packages of sheet film in my freezer (mixed 8x10 and 4x5), one of each size of sheet film in my 'fridge, and a bunch of film holders loaded and ready to go.

As much as I like Efke 100 (and I do like Efke 100), it's going to be hard to justify the price when my current supplies run out. I find that I can do everything I want to do with the J&C Pro 100 for a lot less money. Not that it's the same as Efke, but for my purposes it's just as good.

And, by the way, I believe I owe you thanks for turning me on to the Fine Art Photo Supply fix. You were talking about it in another thread that lead to you sending the sample off to Tom, and your words were enough for me to give it a try. I've been extremely happy with it, and it's all I use for film anymore. (I did try their developer as well, but wasn't nearly as impressed as I might have been. It's not bad stuff, but not good enough to shift me from my current developers.)

Matt, you might try soaking the film in some sodium sulfite and see if it helps with the blue cast. Pretty sure you already do the pre-soak, so a email/PM to John at JandC might be in order. He should be able to help....let us know what you find.

Fix

Mongo-You know it's ALWAYS people like you or Tom who when they make a post I stand up and listen. I know you do photography; not just talk it.....
I'm going to follow suit and make space in the freezer....the Pro100 does have incredible tonality. I just needed to know I could get it to work this time out.
Thanks again,
Peter

jdef.... yeah it looks very slight the blue... I wasnt worried about it effecting printing... the density looks really slight like you said. just wanted to make sure it wasnt going to eventually damage the neg at all because I wasnt adequately clearing etc...

thanks for all the info everyone.

Matt,
I use quite a bit of 8x10 JandC Pro 100. If you want to get rid of the blue cast presoak it with a couple drops of Edewal for 5 minutes. Shawn

I do get a very slight blue when the film is in the wash but it isn't noticable when the film is dry.

My J&C 100 in 120 all comes out green not matter how long I wash it.

5 minute presoak.

It doesn't seem to affect printing though. The first 10 rolls I tried didn't turn green, but the lot that started showing up in the black plastic canisters does.

After losing a couple of rolls because I didn't have a canister or a rubber band with me I decided to abandon it. My wife was berating me just last night because I lost some pictures of a famous huge oak tree in Lafayette, LA due to the roll coming unrolled. Hopefully it will weather the hurricane so I can go back and reshoot someday.

Best,

Will

Hi !
I use, since a long time the Foma 100 Fomapan film.
It's base is blue, nice but blue. Won't the new JandC pro 100 be Foma film ?
What does J&C says about that ?
Regards

I'm sure John from J&C will chime in here eventually, but if you search the archives you can find posts from him in which he tells the full story of J&C Pro 100. It's a film that J&C have made specifically for them in China, and then they have the film sent out (to Europe, I believe) to be cut. The original thread about the film is at: (there was a url link here which no longer exists)

Originally the film was also cut in China but there were QC issues with the first batch of sheet film being cut too large to fit into some film holders...John responded by offering replacement or refund to all customers (at his expense, and you got to keep the mis-cut film gratis), and by moving the cutting to a more reliable location.

The film is not any other emulsion re-packaged for J&C; it's an emulsion that they have coated specifically for themselves.
