negative problem diagnostic...help

Okay, what's going on here other than an old man's ear? Scratches, some dust, but what's the band of mottling going across the images?

Developed in D-76, 11 minutes 1:1 at 22 degrees C. Fixed for 10 minutes in (non-rapid) hardening fixer.

Is it visible on the negative? Just to rule out scanner banding.

 

[dreilly]

Good point. Yes, it is visible on the negative. It almost looks like it's on the surface of the neg, ie, not part of the emulsion. I have them at home, but they might also be on the side opposite the emulsion itself.

I don't know, unless you didn't agitate and/or also didn't mix D-76 completely. It looks like uneven development, but it is pretty regular. All I am also visualizing is a tank sitting there with uneven strength D-76 or standing there with not enough D-76 in the tank so uneven development occurs between agitation cycles. Be sure your fixers was good. You could also try refixing.

Did you use a squeegee on the film to remove excess water when hanging her up?

I used two gloved fingers after a quick dunk in photo-flo solution. Do you think it's water stains?

Don't do that! Looks like you stepped on the negative too.

Dip them again in Photflo for 2 minutes and see if the marks disappear or move. They look like screeches to me.

I'm getting some of this lately myself. What film are you using? It's happening to me with Tri-x, which is what I shoot primarily. That said, photo-flo/water seems a likely possibility.

Doug, looking at this scan I see two things

on the left frame there is a decided pattern of spots that run across the image from L to R ( or talking negs, as it moves thru the camera, ie the scanned image shows them running L to R, however in actuality they run from top to bottom of the frame as it moves L to R from the cartridge to the take up)

Additionally on the right frame there are marks which show movement from L to R as the film advances note an individual "bar" and then the marks below (behind in terms of film advance)

I'm guessing that this camera has dirt. Check the rollers, and interior parts to see if it needs another cleaning. Alternatively it could be there is residue in the film dev tank that is scratching and gunking up the negs. I'd check that also.

use distilled water for the final rinse.
