GP3 100 exp 2015 film

analoguey · Aug 28, 2014

I didnt find much of an issue in the 2015 versions - the backing paper bit. Did you?

ah yes the backing paper. That was a bit of an irritation when using it in any old folders - if the red window wasn't big enough I couldn't see the numbers. Fortunately it's also dense enough that I could use the (very bright) led torch on my phone to peer in without causing a foggy spot

I guess that's probably the only plus to the backing paper. I have one Rollei that this film doesn't want to work in just because of the thick paper backing. The auto-feeler sensor in the camera thinks it's sensed the film even before it gets there. I could work on the camera and adjust the sensor rollers, but as long as I have other cameras to use it's just not worth it. I can live with this backing paper, but it's sure not Ilford or Kodak class. Heck, it's not even Foma class. John W

Of course, I have a Budget substitute for a Rollei, A Shanghai Seagull IV. IF I try to use any "western" film,(tried Kodak, Ilford and Fuji) the film metering roller slips and I only get about 10 of my Shots. But it works PERFECTLY if I use GP3 from the Home Factory.

The GP3 does have that "Home Rolled" look. I also had some Lucky SHD100 where the film was attached to the leader with a sticker that came off. In order to use that I have to unroll the start in the dark and tape the film to the paper with Masking tape. The backing on that looks almost identical to the GP3, but the GP3 is taped with what looks like GOOD masking tape.

I found GP3 to about as sharp as FP4+ can get, but with a nicer grain structure imho, and the tonality is really nice. Ftr, I didn't look at them with low end soft equipment (flatbeds) so it's not missing anything.

Xtol Replenished, 24 degrees, 5m 45s.

pdeeh, I wasn't trying to say GP3 100 was the best ISO 100 film out there or anything even remotely close to that. :

And I wasn't suggesting you were, or disagreeing that it was a very decent film indeed, in fact I said I'd use it all the time if it weren't for the curl and that I might buy some more to see if the latest batches didn't curl ...

Pdeeh, the curling isnt too bad. And I find that the curl stops it from getting creased easily. My delta100 creased very easily. (I was wiping dust off for printing)

Arguably the only issue to be had with Shanghai gp3 is their quality control consistency- otherwise, it's a very pleasing film with its own characteristics

analoguey, every roll i used curled terribly, and I just couldn't stand it any more. Every time I cut a strip for sleeving, it was a major fuss to stop it springing in on itself and scratching itself, and similarly in the darkroom.
Making contact sheets was almost impossible.

I tried all sorts of things from long presoaks to drying it on reels emulsion out, hanging it weighted for days, different humidities in the drying room: nothing improved it

It is always very odd when other people don't have the same experience of apparently identical things, but there you are - I've read complaints that Retro 400S dries with cup or curl, but for me it always dries absolutely dead flat in all planes.

It is, as the great philosopher Toyah Wilcox once sang, a mythtery

Hmm. My delta100 experience (above) with shanghai was when I was getting them set up for contacts.
Not sure what you were using for holding the negatives, but I sandwiched them between two heavy pieces of glass (15"x15" and 10mm thick).

I guess thats quite the issue isnt it - if QC was more consistent it would behave quite similarly.

well the point was that the strips of cut negs curled into circles, so it was almost impossible to get them flat under my contact glass without growing a third (sometimes fourth) hand, and they often got abraded in the process

This 2016 batch (I made a mistake and said this was a 2015 batch and it's really 2016) has almost no curl to it. At least for me anyway. Maybe it was because of the 1hr stand in Rodinal or that I dry my 120 film horizontally? The next roll is going through my Rollei and will be souped in WD2D+ pyro so will see if that makes any difference in curling. John W

Hmm. That.
Curling into circles isnt something I have experienced - not with strips of 3 or so. There's some curl, but not that extent.
That much can be painful - I find that quite irritating when I have to roll it onto dev reels.
Does taping help?

Mine curled in Rodinal, paRodinal, (both of the latter in normal agitation and stand ) D76, Adox MQ Borax, Caffenol and Hypercat ... no difference in curl

I really must see if I can get hold of some of the later batches and give it another try.

analoguey · Aug 29, 2014

Hehe. You must contact the Shanghai manufacturers to do QC then. Make some money off the curls! ;-)

Yes, I have the glass negative carrier for my Nikon 8000 scanner and if there is even moderate curl it's a bitch to get the top door closed without the film skewing in the holder. I had no problems with this 2016 batch of GP3. In fact it was very easy to scan. Well, off to the cottage for a fun weekend! John W
