Dear Topaz,
My father took lots of slides many years ago, all of them are blue.
Blue like Smurfs.
I’m trying to batch improve them. No problem for the first picture, but the rest hasn’t been improved.
I made a 2nd test on my 2019 MacPro, and I had to individually click on every picture to have the colour balance improved. Sharpness and noise don’t cause any problem, they were applied to every picture.
Perhaps a problem to solve at your end. I’m fully available for further informations at makilatv@gmail.com.
Many thanks for your work !
