develop 35mm, got lines

anon s · Jan 23, 2019

hello!

I am developing 35mm.
I put 2 reels in a tank and both films got lines not all but on many images.
no idea...but I guess it come from some developing process or my way of loading films onto reels...

this is how I develop films

35mm x 2 reels
paterson tank 600ml each liquids

no pre-soak (fomapan 400)
develop : first 30sec agitation, then every 10 sec per min.
stop :normal water
fix : 1st and 2nd fixer

any suggestions are welcome, thanks in advance

I cannot see lines but evidence of dust/hair that has been picked up by your scanner. Try using an air blower on the negs before scanning.

Well, 600ml of chemicals should be sufficient for 2 rolls in a Paterson tank. I've never seen this problem using Paterson reels either. If you're talking about the light streaks at the top of each image, this almost looks like streaks from water drying on the film, or from wiping it while still wet.

Do you dunk the film in Photo-flo or wetting agent before hanging to dry? If not, I'd recommend trying some (mixed with distilled water, not tap) after your final rinse. Just hang the film and don't squeegee or wipe it.

hi nose2,
thank you for your comments.
I put marks to emphasize the lines on the images...
yes, I could be more careful about dust !

hi Jimjm,
thank you! yes I use wetting agent + distilled water before hanging film.
I had the same kind of problem with 120 before... but it solved when I gained the all of liquid from 500ml to 600ml...

Looks like shutter-curtain bounce.

no, shutter curtain bounce leaves an over-exposed strip along the edge of the frame that is where the shutters stop.

This looks like a scratch -- you don't mention what kind of camera you are using, but take a gander at the pressure plate...all clean? Nothing sticky/gooey/rough/icky on it? It would be on the bottom edge, nearest the bottom of the camera.

Another possibility -- if you bulk load film, you have grit/dust/ick in the felt of the film can. Clean the felt or just toss the can.

And you didn't use a squeegy on the negatives did you? Never, ever, use those -- just rinse with water and photo-flo and hang to dry. You do take the film out of the reels to dry it, right?

The artefacts in both phoptgraphs difer:
-) a fine line
-) a strip

A scratch would be sharper; these ones are more diffused. I had something comparable on a 100ft roll of Foma400, but it was minus density (a dark line on the print) instead of plus density (a light line like shown here). In my case it was a film defect as I could exclude any other cause. It also appeared consistently - as long as there was some image information for the artifact to stans out against. I switched to a different 400 film...

As others have implied, it could be a pressure mark or a broad rub from emulsion build-up on the pressure plate.

Pressure marks can be made when rewinding the cassette under too much tension over an uneven surface.

In any event, you're luck in that it is very near the margin and can be simply cropped out.

I used to get lines like these when I used a specific camera - lens combination, an Olympus OM10 with the OM Zuiko 28mm f/2,8. The same lens on another OM camera wouldn't cause it. The same camera with another lens wouldn't cause it either. I suspect it was an internal reflection that I never cared to investigate further, it was close enough to the border and wasn't hugely annoying, I could just crop it out as Kino said.

tezzasmall · Jan 24, 2019

I can see the lines at the top of both sets of prints that you have provided.

I would side with something being on the pressure plate. Run a clean finger over all of it but especially at the bottom and see if you can feel anything that shouldn't be there.

Do you agitate by inversion or by using the swirling stick?

Saganich · Jan 24, 2019

I was wondering if your were seeing this artifact from a scanned negative as opposed to it actually being on the film? This happens to me often and there are issues with scanning and holders causing similar artifacts. I would rule out scratching, but other possibilities include agitation with harsh inversions rather than "Lazy 8's", or possibly reel contamination.

hi friends,
thanks for all of your input.

I shot the images which I attached with yashica T3.
today I brought color negatives to lab and scan at home, I got the same kind of lines...
but the other film which i shot with another camera, there was no line.
So that means the line comes from the camera.

thank you so much again! I will clean the plate. as many of you advised... when I meet better result, I will let you know !

@brendan, I agitate films by inversion

I would not rule out the possibility that it is an evil spirit. They do this sort of thing.

But I'd still check the pressure plate.

If that's correct its not a base plate issue but an internal exposure light reflection issue.

develop 35mm, got lines
