Hi'
Trying some tests with my Flats.
If I Process a master Flat >division with a duplicate...
I Get a perfect grayscale like this (No science only math
If I then change the display setting in any way I can't get back to the same look.
How is that ?

And next..:
The First Image was made the same way displayed as Auto.
The second picture was preprocessed with the flats loaded both as Image and Flat. Displayed as Auto
How come is it now noised ?

Hi,
1) I didn't understand well the problem, but the fastest way to restore a visualization is clicking the Status Bar of the image (the one which shows R = ... B = ... V = ...) or pressing F4.
2) The two visualizations are different, the first is V = 22434 .. 22434, and there are no pixels brighter 22434, so the image is display black.
The second image has v = 22434 .. 22435, and the max is 22435, so it's possible to show in shades of gray the pixels between 22434 and 22435 (the visualization range is 1.0, not 0.0 like in the first image).

Thank's
1) I know the visualization via. Status bar or context menu. But it can't show me the "right" picture, as right after a division with a copy image.
