Alan Marcus Posted October 3, 2020 Share Posted October 3, 2020 I think the pour of the developer into the tank was not steady and quick. I think the pour was interrupted. The developer is mainly water. The film emulsion is a dispersion of silver salts in gelatin. The waters of the developer soak into the gelatin, this action causes the gelatin to swell. This swelling allows the developer to freely percolate within the emulsion. It is free to enter and exit. The rate of swilling is critical, if the pour is interrupted, lines like the ones depicted, will result. Link to comment Share on other sites More sharing options...

Alan Marcus Posted October 3, 2020 Share Posted October 3, 2020 (edited) @ Luis-esco - Am I right? Was the pour interrupted? Edited October 3, 2020 by James G. Dainis Link to comment Share on other sites More sharing options...
luis_esco Posted October 3, 2020 Author Share Posted October 3, 2020 Maybe. I was using a 500cc glass bottle with a little mouth. I will try tomorrow with a a large recipient for a steady and quick pour. My fear was a camera's fault. But the line is rising in negative 1 and 2 until negative 3 ( picture above ).

rodeo_joe1 Posted October 3, 2020 Share Posted October 3, 2020 Are you sure the lines are actually on the film? Because those look like scanner lines to me. They're parallel to each other, but not at all parallel to the edge of the film. They also look nothing like any filling marks I've ever seen. They're much too fine and well-defined for that. Filling lines would also be parallel to the film edge. What the heck are we looking at anyway? Looks like a negative of an out of focus skewed grey card with a white target inked onto it. Why?

Niels - NHSN Posted October 3, 2020 Share Posted October 3, 2020 What the heck are we looking at anyway? Looks like a negative of an out of focus skewed grey card with a white target inked onto it. Why? LOL. Yes Luis, you better explain yourself! ;-) Anyway, if it it turns out to be filling marks and if it persists, you may want to try to pre-soak in regular water before you add the developer. It worked for me many years ago when I had a similar problem - and I actually still pre-soak out of old habit. Niels Link to comment Share on other sites More sharing options...
rodeo_joe1 Posted October 3, 2020 Share Posted October 3, 2020 It's not filling marks. It's either scanner tramlines or some very weird coating fault. Link to comment Share on other sites More sharing options...
luis_esco Posted October 4, 2020 Author Share Posted October 4, 2020 Problem solved. Thanks to all of you. I will never use this Paterson Film Squeegee again. Link to comment Share on other sites More sharing options...

rodeo_joe1 Posted October 4, 2020 Share Posted October 4, 2020 Rubber squeegees are never a good idea, but those lines still don't look like squeegee scratches. How do the lines stay straight while the film is obviously curved in that 'scan', snapshot or whatever? Squeegee scratches and filling marks are almost always parallel to the edges of the film. And they simply can't stay straight when the film is curved. Link to comment Share on other sites More sharing options...
rodeo_joe1 Posted October 4, 2020 Share Posted October 4, 2020 You can see dead straight density variations all the way across this inverted and contrast-enhanced version. The lines don't follow the curve of the film edge at all. They look much more like artefacts of the scan or copy. So how was the negative digitally reproduced to show here?

James G. Dainis Posted October 4, 2020 Share Posted October 4, 2020 Look at the film. Are the lines on the film itself? James G. Dainis Link to comment Share on other sites More sharing options...
paul_noble Posted October 5, 2020 Share Posted October 5, 2020 It seems to me that scanner lines could be ruled in or out by re-scanning the negative in different orientations; rotate the negative 90 degrees between each scan. Perhaps scan on a different area of the scanner if that is possible. If the scanner is producing the lines, they should change with the different scans. If the lines remain the same orientation to the film, then the lines are actually in the negative. Link to comment Share on other sites More sharing options...
