LaserSoft Imaging

Hello

I have a problem since ever with NegaFix. It always changes when I alter the desired frame.
Since I want to Scan a little around the actual negative to get the rotation right afterwards.

So, what NegaFix does is clear to me. But not it's random color/contrast-changing as soon as I change the frame (red box).
See the two screenshots:

The left one is fantastic for me. I had to play with a lot of different frame sizes and positions until i was like "this is what the colorcopy looks like"!
The right one is awful, but right for scanning. If i look now at my contact sheet it's just a giant difference and i dont know how to tame negafix.
The Screenshots are same settings! And yes, I deactivated Auto in the General settings...

Please I need some help with that

Kind regards

P.S. I have the Epson 750 PRO with Ai Studio, but no HDRi-Option, how come?

Its correct, it always changes depending on the image content included in the scanning frame

It is not random, again, it depends on the image information contained within the red borders of the scanning frame, if you change it, its content also change.

Great, but it is a subjective choice. The color copy is also a different photographic material which does not match the characteristics of the film itself.

"Awful" is also a subjective judgment. Again, your contact sheet is a printed copy in a different material than that of the film itself, or the the scanner, or your monitor. The NegaFix profile is giving you a similar reproduction of the actual film (however that is also impossible to see because it is just in the digits of the file itself).

Deactivating "Auto" in the general settings is not enough in this case. You must first click the expert settings button in NegaFix, then the Expansion tab (Ausdehnung auf Deutsch), and then untick the "Auto" checkbox located at the lower right corner of the Expansion tab (this should be done after you have reached the desired adjustment, after that you can resize the scan frame to contain the rest of the picture).

P.S. Have overlooked this

HDRi modes are only available in transparency mode.
