An hybrid area on how to properly use a scanner is badly, badly needed on APUG

*
All the dramatic differences we are seeing on this comparisons are just differences in scanning, scanner calibration, filtration, etc.
The picture above, in post #27, shows how moot is to compare a film with another if the scanning work is not properly executed.
So which is the "real" Kodak Ektar 100? The one to the left or the one to the right? Or one of the thousands filtrations more that can be obtained by using different settings?
My scanner if not profiled and if used with default settings has a slight green cast. That doesn't mean the film I scan on it has a green cast.
With negatives there is no "reference" and automatic settings will easily grossly fail, besides failing in a different way for each different setup.
Just as an exercise I tried to re-filter it. The result is certainly suboptimal due to the fact that curves have already been applied, that I was not there and I have no idea which colour was the grass, or the "grey" arm of the crane.
This image shows the great difficulty a printer has when he doesn't know the scene and has no known reference (such as a Greytag chart in the same light conditions).
The final result can be anything.
* I know, I know, this has already been debated, just saying.
(I see the sky as a bit too magenta and the rest of the scene a bit too yellow in general, probably).
