Issue with B&W film development

[jarek_waw]

Hi,
I did develop my first film (hip hip hooray).

I noticed on some photos strange signes like the shadow lines or trees (see attached photo).

Do you have any idea what that could be, i.e. what I did wrong?

Or a double exposure.

These do look like bare branches of trees. They seem to be spaced out as small trees would be if they were planted in the ground such as say small fruit bushes that have no leaves. It looks like an accidental double exposure to me. Can you remember having your camera outside and near some small bushes in the ground that had recently been planted where you may have accidentally pushed the camera's shutter button?

HI,

On other pictures there are just lines, see another example.

Static electricity discharge

Certainly.

There is/was a recent case of this, on Fomapan film as I recall. It seemed to be a factory defect rather than caused by the photographer in their workflow. What film was this, @jarek_waw ?

And welcome to Photrio

 

[jarek_waw]

Fomapan film ...

 

[koraks]

Ah, here it is: https://www.photrio.com/forum/threads/ragged-branches-on-emulsion-side.199193

That one was on Fomapan 400. By any chance the same film you used? If so, I'd contact Foma. They might replace your film.

I'm with Matt dbl exposure. Need to see a photo of the negative strip. Did op remove a partially exposed film, then put film back in? Something is wrong. Unless this is trolling

 

[koraks]

Unless this is trolling

Why would it be?

See the thread I linked to - identical defect.

 

[DeletedAcct1]

Foma strikes again. With problems of Fomapan 400, Foma 100 R (there's a topic about) and whatnot, what is happening at Foma?

 

[Sirius Glass]

Static electricity which occurs when film is advanced quickly in very dry weather. Advance film more slowly.

Welcome to APUG Photrio!!​

 

[jarek_waw]

No trolling. Neither double exposure. The film is Fomapan 100 shop loaded from bulk. (I used a cheap film for the film developmet training). This video describes such effect: .

Thank you ALL for help .

It's virtually impossible to force this effect in-camera as a photographer. It's more likely caused during film confectioning.

I had it happen to me so I know that a photographer can force this. When it happened, it only happened that day on that roll when I advanced the film quickly, never when I advanced the film slowly. I was very aware when I advance quickly and when I did not. There was a very direct isomorphic relationship to the speed of advancement on a very dry windy cold winter day.

Is this phenomenon confined to very dry and cold days, Sirius and what constitutes such conditions in terms of temperature and relative humidity?

I'd have thought that such cameras as F100 and F5/6 on continuous mode or even slower cameras that can only manage say 2/3 frames a second would exhibit this. Maybe they do. It's just that I haven't seen complaints about this on Photrio amongst such camera owners nor even any warnings to avoid such modes on those cameras with a continuous frame advancement in cold, dry conditions

Thanks

As I stated. Dry cold windy well below freezing. Winter 1963 with Kodak Tri-X film.

 

[DeletedAcct1]

Two same identical problems on the same film can't be a photographer's fault. It has to do with Foma.

 

[titrisol]

Those are electrical discharge marks, if you found it in several places it is a film defect.
This has been reported a few times over the years, mostly in Foma, Forte, etc. films.
Call the place that sold you the film and complain, they should refund you and send you a roll

OK Was that the only film and only winter and was this in SoCal? I was hoping to at least narrow down a range of the actual conditions in terms of humidity and temp that may cause this issue

Cold and dry.
So probably not frequently encountered in much of the UK.

Well the winter of 1963 was pretty cold but I have no idea how dry it was compared to SoCal. Just trying to get a "feel" for what the conditions might have to be like for what caused Sirius' issue.

Static electricity discharge

that's my guess too; sometimes happens when the film is pulled out of the canister too fast or into a plastic spiral too fast.

I remember watching the sparks fly, way back in the 70's when tearing the paper tape that EK used to tape the 35mm film to the spool. I never had any marks. This is fascinating, 3/4 inch long sparks, can't see this happening in camera??

I buy leather moccasins from a place in Canada. Brown Bear company, they sell slippers with copper rivets to ground wearers. Probably not real popular with electricians.
