Out of curiosity i also took a look at the two scans brbo showed - and to check for sharpness and grain i zoomed in on both scans to the same spot, to the cylinder lock on the trunk of the blue car. I had both pictures in to different tabs and then switched rather fast between both pictures, to check for small differences in sharpness or grain.
And i found that sharpness and grain basically is the same...
... but not subject detail!
Especially the license plate holder on the blue trunk does differ in shape - there is a lug on the emulsion out scan, which is not present on the emulsion in scan:
Red arrow, no lug -
- but now there is some sort of lug, which wouldn`t make sense as it would lift the license plate. This "lug" must have been inserted by some image-improving-software.
Red circles show areas which also differ, on the upper red circle chromium seems to bleed into the blue paint, in the lower red circle the chromium sheet itself differs in shape.
To see the differences in both red circles best, one should open each picture in an individual tab and then swap between both tabs rather fast, like within one second.
Another part of the subject also is altered:
Here is some brown dirt on the black tire of the car standing behind the blue car -
- and here some of the brown dirt is gone, as if someone cleaned the black tire a little. Also the tire tread differs a little in the red circle - but this only is visible if you swap between both pictures rather fast.
Then there are orange circles in several perforation holes, these maybe are air bubbles from the fluid used to prevent Newton rings - but quite some of these orange circles are symmetrical to 100%. Some are oval or non-circular, but a lot are incredible symmetric. The symmetric ones are indicated by a red arrow - you need to zoom in to see how symmetrical they are:
Making me wonder whether you can have so many entirely circular air bubbles or whether an image-software decided to shape several air bubbles to perfect symmetrical circles.
Also i wonder why these circles are orange at all. If these indeed are air bubbles, why do they have basically the same orange as the edge markings on the film?
Seems like an image-software decided to color possible air bubbles to the next nearby color which would be the orange of the edge markings.
