First of all, I apologize for my poor English, which comes from an automatic translator!
I’d like to find a solution to my problem: When I convert a series of images, I never get to have exactly the same colors from one photo to another.
Example: I reproduce a series of negatives showing a character running in the sun. The photos were taken with a camera with a motor drive, with the same speed and diaphragm. So exactly the same exposure.
The reproductions of the negatives with my Nikon D850 are all identical (manual flash for the light, exactly identical settings from one photo to another).
I make Negatif Lab Pro work for the first image. I choose all my settings, and I have a perfect result. I save these settings.
Then, on the following negatives, I make Negative Lab Pro work by applying the saved settings. The result: colors are not the same from one photo to another. However, I did remove the black margins from the negatives.
The proof that my reproductions are not in question: when I copy / paste the settings( in Lightroom) of the first photo on the following ones (Ctrl-C / Ctrl-V), this time, the colors are regular. But unfortunately, when I open Negatifve Lab Pro, the software changes the colors again.
Do you have a solution to this problem?
