Another 'what is this' (waving line on negative)...

[brbo]

I developed a couple of 135 rolls and one 120 roll in xtol last evening. 120 roll had a strange line running along the whole strip. Line waving pattern seems consistent in frequency and amplitude along the whole length. I think it is a little more pronounced at the end of the rolls than at the beginning.

Any clues what caused this?

Not entirely sure but the half moon shape looks like a kink mark caused by forcing onto the reel.

I had this wavy line as well when I first got my M4 and thought that there is some kind of light leak..... sent the camera back to the dealer for a check up and turned out that the camera is ok.

Then, the same thing happened when I used another camera..... my conclusion is that i've got a bad batch of Tri-x

It is probably trace of xray. Did you pass your film from x-ray?

 

[sevo]

Positively X-Ray - that is the effect of a scan line of some exposing radiation hitting the film at an angle while wound on the spool. High intensity too, carry-on baggage and postal parcel scanners are film safe and will at the very worst leave some fogging.

If nobody carried the roll through some aggressively scanning high security (military/nuclear power plant/etc.) checkpoint, that roll has been though a (oldish) check-in baggage scanner.

Yes. I intentionally left out that bit of info in my post as I didn't want to lead someone to this answer*. All my films went through at least 4 x-rays. I didn't bother requesting hand inspection as I mostly had slow film with me (with just a few rolls of tri-x, fuji 400h and portra 400). I have had my 7 135 rolls developed at the lab and didn't notice any fogging in them (but I didn't look for it, just a quick glance at the negatives) and I'm now starting to develop BW negatives and the 120 C-41 films. I still hope this is not from x-raying as I would really hate to have fogging on 10+ 120 rolls. In fact, slow film (this is delta 100) should be less affected by x-rays. I also developed another roll of delta 100 that made the same tip the previous day and it came out ok, but I will check again if there is any fogging.

Fingers crossed! Iceland is so beautiful (without the fog)...

* I had a debate on this forum where I cited various credible sources that x-rays fogging the film is in fact a real possibility, but was dismissed that there hasn't been ANY proof of that in the real world. I didn't want to come back a few months late to say 'i told you so'... Especially after being aware of the danger and still putting all of my film in the bag. :bang:

Shi***! I put my film in the carry-on bag, but I now recall that my wife rearranged our stuff before we left because of the weight limit on individual bag. My film might have actually ended up in a checked-in bag. Grrr...

For reference: Kodak on Baggage X-ray Scanning Effects on Film.

 

[clayne]

Definitely looks like film that's passed through checked in luggage scanning. Sorry my friend. Tell your wife to bring less stuff or put her in checked luggage.

I will tell her that!!!

(If I don't post here anymore, you know that "...so we had to stop every effin 10 meters and all you can show me is FOG?!..." was not the only thing thrown at me)

Actually I haven't cared about the x-ray pass and this is the first time I see in real world 🙂. In here we have lots of shopping malls, museums and other big public buildings and almost every where you have to pass your bag into the x-ray before the entrance. Probably I am passing my every film at least 2 times for years. Moreover I sometimes order films from abroad and they are passing postage x-ray. I have never faced such a problem. I think it is just unfortunate of you. May be you can turn this an art object 🙂

It's because the carry-on luggage scanners are not as powerful as the ones used to scan checked luggage. I've also never had film damaged by those conventional handbag scanners, but would be very worried if I had to leave it in a checked bag.

You should print this image on a t-shirt to wear through airport security when they give you static about doing a hand-check.

ON second thought, that insolence might get you arrested.

LOL!

Just developed Tri-X and Fuji Pro 400H. Trix-x is bad, fogging much more pronounced than on Delta 100.

C-41 film is fog free!!! I hope the rest (or at least some) of my remaining C-41 rolls will be OK, too.

 

[taylan]

I just indicate there are two exposed part at the top section of the image and there are two "20,00%" phrase. What are these and how can it possible? I marked the sections with yellow at attached photo

 

[brbo]

I scanned this on a printer-scanner-toaster-multi-purpose device with a sheet of paper behind the negative that had some stuff printed on the other side...

I don't know but you should post this picture in the "minimal" thread 🙂

 

[Livesteamer]

Thank You Taskoni. I needed a laugh. Joe

Exactly.
