Made a mistake during development..

I've recently been experimenting a lot with new films & semi-stand developing techniques.

However my film from this evening came out looking like this at the edges →

& I was wondering what causes that white chalk-like fogging along the frame numbers. The film was Acros 100. I'm assuming it occurred during the development of the film opposed to beforehand? Does anyone know what happened? I'm interested in learning where I went wrong & improving for next time. Thanks in advance!
 
Did you have enough dev in the tank?
 
@RaglanSurf ..I thought so. This is the first time it's happened to one of my films & I usually use the same measurements. Can not enough developer cause this? Perhaps there wasn't!
 
If it was only one edge (the top) and you didn't use inversion then it's possible, but the picture looks like both edges unless I'm mistaken.
Is it rough ? Could it have been scratched either in camera or on the dev. reel ?
 
I don't do stand development but as this is consistent along one edge of the film it looks like the likely cause to me. Was the spiral pushed all the way down onto the central core?
 
@RaglanSurf Yeaaaah the spiral was far enough down inside the tank although I perhaps should have inverted the tank a little more to avoid the slight strip of underdevelopment along the top of the frames. I'm more concerned about the chalky edges tho!

@John_oh Yeah both edges on either side of the frames are fogged a chalky white but don't feel rough, smooth like the rest of the film. It's something I've never seen before!

Mmm, clutching at straws now, was the spiral clean and dry when you loaded the film?

I believed it was but I hadn't used it in a few weeks.. perhaps there was chemical residue in the ball bearings!? Perhaps! What an amateur mistake! Hahaha.

That's what I thought but then the spiral would have been through the rinse process last time you used it wouldn't it? I wash my films for about 10 minutes so I can't imagine there would be enough residue to cause that much fogging/marking.
 
Looks a bit like insufficient chems to me, although ive not seen it in person, could you give us a close up?

That was my initial thought but the marks are on both sides of the film :shrug:
 
exhausted fixer....


jox shoots....he scores.....the crowd goes wild






re-fix....:D
 
Both sides... Hmm i'm starting to think chemical contamination. I know that dev and fix tend to go chalky if they mix (don't ask :D) so it could be that you didn't stop enough.

Feel free to ignore my ruminations if a better idea comes along :D
 
well....its kinda up there in the recess, a weak mix and/or minimal agitation will struggle to be completely effective.

seen it on my own stuff, and that's what it was....knacked fixer













either that...or its sumfink else...lol
 
Mmm actually, it could have been insufficient stop chemicals.. I'm just thinking back over the process & perhaps I didn't do it sufficiently. I've just never come across this before! The {correctly exposed} frames are uneffected. I'll take a better photo of the edges for you, one moment!

Yeah & come to think of it, it wouldn't be as consistent down the entire film would it..
Unless this is the usual situation with Acros 100 & I'm being an utter fool!?

I had to place the film onto a black tee shirt for it to show sufficiently. This is strange! Am I right? This was only an experimental film but I'm curious as to what caused it hahaha.
 
Looks to be that the developer or fixer didnt get into the grooves in the spiral, seeing as it's not affecting the images i wouldnt worry about it

Mm thanks for clearing that up, it's just the oddest thing I've come across since dev'ing my own film at home.

It's one of the more bizarre developing hiccups I have seen :thinking:
 
*edit - never mind!

Hahaha! Baffling.
I just had to ask if anyone had theories about what'd caused it 'cause I just had no ideaaa :)
 
Well i'm afraid I can't offer anything more than what others have already mentioned, however i would suggest you check your dev room for...................









.................GREMLINS!!! :eek: :nuts: :D :D
 
This usually happens when, for whatever reason, the rim of the film gets 'stuck' to the edges of the reel that holds them in, which means they never ever get any chemicals and turn white. Same thing when film overlaps each other and causes underdevelopment... except in this case it is extreme underdevelopment.
 
was the picture taken just before you threw (?) the film in the bin ? :D

Hahaha obviously I wouldn't hold a valuable film like that! Yeah there were a few mistakes made during development so none of the frames were what I'd consider usable. I just wanted to show the white edges. The films I keep are kept in pristine condition & I'd NEVER get hand/finger prints on the emulsion haha!

Thank you for clearing that up for me :)

I wouldn't consider any of the above explanations as "clearing it up for you".
You are doing something very wrong during your processing procedure and have not found out what it is .Film does not just stick to spirals for no reason, or as a matter of course. I have been developing films B&W,colour negs and transparency for 40yrs and have never seen that sort of thing as a matter of course.:thinking:

I disagree, even if i tried on purpose i wouldn't be able to get the same discrepancy
