As the bottom anomaly is not a drying mark you need to see what is causing it. Newton rings become a problem when two smooth shiny surfaces are put into contact with each other, hence my question about do you use a glass negative holder? But they can also be caused if you have a curved film surface which reflects the light within the base layer of the film. In either case you want to try scanning the film the opposite way up to the way you have been scanning it. This may reverse the image as it normally comes out of the scanner, but you can invert it via the scanner software or in Photoshop later.

Woah! My negs do have a curve when I scan them as I do so pretty much immediately once they are dry. Maybe I should wait a few day until the negs "relax"? I will check your idea but isn't there an adverse effect if I scan them with the "Not Shiny" surface?

 

And I don't use a glass negative holder, but the plastic one that was supplied with the scanner. Unless I am misunderstanding you?

Okay, went home, scanned the same image and low and behold, that weird streak is nowhere to be found. Thus, I think 250swb may have been right about the curve as the film was very flat this time around. I will keep a good eye on things and see how the situation develops (pun sooo intended) but I think I may have been over eager to see the results of a couple of experiments and didn't wait for the film to properly uncurl.

 

Again, thank you all for chiming in. All of it is valuable information.

I don't think you will see any difference, other than the image is reversed. For what it's worth the Epson V700 scanner instructions do actually say scan with the emulsion side up and the Epson Scan software does automatically reverse the image. They may have introduced that suggestion after experience of just such a problem as yours. Who know's?

Marks if not mechanically caused are from poor agitation most frequently in the first 30" to 60".

 

People are convinced that marks are from too much agitation, so they slow it down and get bromide streaks and underdeveloped areas.

 

When film is first immersed, the wet/dry edge needs to proceed across the film rapidly and with without stopping/retreating. I drop a loaded reel into the prefilled tank, cap and agitate immediately.

 

Check your fingerprints, wash and dry well or wear gloves and handle film by edges only.

 

Photoflow works in soft water 1:500 and 1:200 in harder water, 1:50 if really hard.

 

Leave in Photoflow a full minute with considerable agitation.

 

Rinse tank and reels with plenty of hot water and allow to dry.
