It is just the leader and trailer, yes?

Yes.

It seems that the start arrows are inaccurate as they are for 120 film. In my GW690III I managed 15 1/3 images, but there was plenty of room for 16. The start arrows come up too soon for 220 film.

Weird thing - it stinks like mothballs. Never noticed the smell of backing paper before on any other 120 or 220 films that I have used

I wonder if this came from a bunch of long stored 120 backing paper.
Does anyone recognize the backing paper?
I don't have any 220 backing paper - other than as part of a few remaining rolls of Portra that I don't want to open now - so I can't measure the 220 starting position for you.

From a quick Google search , the backing paper appears to be Shanghai GP3 backing paper for 120.
The mothball smell says a lot, I think.
I am no 220 film expert but the photo of the backing paper looks like it was 120 paper cut and stuck to 220 film. To me it looks a bit like a homemade job.

Well yes, my photos of the backing paper in this thread show the text 120 all over it.

Film dried over night, will scan this evening. There are no identifier marks, or any sort of edge marks, on the film.

Huss · Oct 27, 2020

The film has excellent sharpness and very low grain - at least developed in DF96 Monobath.
Of note one can see a vertical line on the left edge in the first pic. This is visible in a few of the images. So now I need to figure out if this is a flaw in the film, in the camera (GW690III) or in developing (perhaps the cheapo Arista reel is causing it?)
Never a dull moment!

Nice results! Did you shoot this film at box speed?

Yes shot at ISO 400.
Thanks!

Dark in the print is low density. That'll be either a film defect or a developing problem, since you don't have a focal plane shutter that could produce that kind of issue. The streak is lengthwise on the film, so very unlikely the Arista reel is to blame. I don't know what in developing could cause this kind of streak (as opposed to a tide mark or something related to solution level) -- so to my eye, this looks like a film defect.

If something on the reel was damaging/scraping the film, that could come through as a dark streak. Where the streak is is where the film continuously passes through the feeding ramp as the film is loaded onto the reel.
If there is build up of dirt/chemical residue there it could cause this. Or perhaps something in the Fuji on the pressure plate. Or it is a film defect..

I am going to soak my reels then rinse them off, and check the Fuji if I can see anything. Then if I still get this it points to a film defect.

The actual images are much sharper/clearer etc than these Flickr downgraded samples. So whatever the film stock is, I really like it. And it seems to be accurately rated at ISO 400. Those two shots were exposed at 1/500 f13.

Lab Box? I'd normally expect pressure marks to show light in the print, but if emulsion was scraped away, it's possible it could print dark.

Not lab box, just regular reels. There is that feeding ramp on the Arista reels where you insert the film to load it, and the entire roll passes through it as you wind it in.
It's that, or something w the camera, or something with the film itself.

Of course this is the first time I've seen this issue.

Donald Qualls · Oct 27, 2020

Oh, right. I have actual Paterson reels, they don't have that big plastic protrusion.

MattKing · Oct 27, 2020

I've been using those Arista reels (badged as AP) for years, with zero problems. I've been using them with Kodak films of various types, but I frequently load two 120 rolls on to a reel.

Huss · Oct 27, 2020

Yeah, I've never had issues before. Checked the Fuji - looks squeaky clean inside, so that's ruled out. So it's either the reel or the film. Not much I can do about it if it's the film apart from use up the remaining rolls! We'll see how the rest works out.
I could shoot a regular roll of 120 in the Fuji and use the same reel and see if that has the mark.

MattKing · Oct 27, 2020

It could be the leaders/trailers and the handling when they were attached.
And one final possibility - does the 220 setting on your Fuji move the pressure plate? Could there be a pinpoint light leak there?

You have to manually flip the pressure plate to the 220 side. I had no issues a couple o weeks ago w Trix 220.

BradS · Oct 28, 2020

but wouldn’t a light leak show as bright on the print? The defect is the dark line visible in the sky in two of the three photos above, is it not?

BobD · Oct 28, 2020

Must be a dark leak.

Whenever I have a dark leak, it lets the dark out. Never seen one run the other way...

Lachlan Young · Oct 28, 2020

It may well be either an interlayer drying/ flow mark, or a piece of dust in the scanning system.

Scanned with a digicam, so essentially it is photographed. A piece of dust would show as a white spot.

I like the way you think!

grat · Oct 29, 2020

Well, that would tie in with the concept of light bulbs actually being Dark Suckers. It only stands to reason that if they consume dark, they have the potential to leak it.

Look what the cat dragged in...
