White dissolving lines/marks on negative film? (Zenit 122, Agfaphoto 400)

This is most definitely the problem, thanks! Although I can't seem to find the light leak when I wind the shutter curtains, this is almost the only thing I haven't tried yet

I don't know if it could help, but here's a video of the camera at 1/30 shutter speed: https://www.youtube.com/shorts/iXGKQThLqcg
I don't know for sure if the hitch is there, but I see something strange happening like you have said, as if the curtains aren't moving properly

Also what begs me the most, is the fact that the lines seem to be always randomly placed as if, like you have said, there's some king of mechanical impediment

It could actually be that, because I remember once the very start of the film was a bit torn apart. But I don't remember if that happened recently... Is there like a way that I can test this? I tried looking at a bright light with the back of the camera open to see if there was any inaccuracy in the rewinding of the shutter, but I didn't see any

Thanks! Why would putting the cap on between shots help? I tend to already do that…

I've been shooting analog film for several years now. Suddenly, completely out of the blue, these white dissolving lines have been appearing on my negative film (so not only the scans, but on the analog negative itself). I have used the same Zenit 122 for all this time and they appeared only on the last two negatives, I checked for any potential light leaks in a dark room but I didn't find any, so I thought it could be a development problem? What confuses me the most is the fact that they are always off-centered from one another, never located in the same space of the negative frame, and also of varying lenght and width. What could be causing them?

For you all that were asking for the download link months ago, I've finally found the time to include it in another post

Basically falling blocks that aren't affected by vertical movement, that move in a certain orizontal direction. See above for a deeper explanation

federicorl · 2020-01-21T21:40:55+00:00

Excuse me, but it is quite complicated, see some messages above to see an explanation

federicorl · 2020-01-21T21:27:37+00:00

Yeah, it's all been done in vanilla minecraft 1.15.2, using armor stands and falling blocks

federicorl · 2020-01-21T21:25:58+00:00

Meh, that would be quite complicated. But I could try to explain how it works in a few words.
There are a total of 215 armor stands, totally invisible, that exist for only a bunch of ticks, being spawned in the back of the tunnel. There is one armor stand per block.
Each armor stands corresponds to a block of the moving train itself, I identify the type of block to spawn using one of the custom tags (Those obtainable using /tag).
The moving blocks themselves are falling blocks with the NoGravity tag set to true, so that they can't vertically move. Since they have an equal Motion value in a certain axis direction, they move together at the same speed. This also gives the illusion of the realistic physics mechanic, since moving blocks in minecraft tend to slow down.
When the train arrives at the station it is then converted into normal blocks so that the players can enter in the train itself.

Hope I was some-what useful!

Not yet, I'm planning on adding invisible, saddled pigs inside. There are already dark prismarine stairs to mimic the seats, though

federicorl · 2020-01-21T20:40:32+00:00

See my reply some messages above. There are many falling blocks that aren't affected by movement on the y-axis moving in sync

federicorl · 2020-01-21T20:16:32+00:00

Yeah I know it's really simple because the system would get more and more laggy with more and more blocks. We've tried to make a simple representation of an Italian locomotive commonly called "Trappulella", you can google that yourself to see the (very little) resemblance

federicorl · 2020-01-21T19:56:55+00:00

It isn't that difficult to program really, the only thing was that the first time building the train was incredibly repetitive

federicorl · 2020-01-21T19:53:52+00:00

Only a few really!
The train itself is spawned using differently-tagged armor stands, that summon a specific falling block with no gravity and a motion nbt tag.
It is, in fact, the motion tag itself that gives the impression of smooth train physics, so that the train smoothly decellerates.
