Good morning I'm making some masks to create a desaturated zone and to be more precise zoom at 1:1 or even 2:1 . but the computer is not behind me and freezes and often crashes. I enclose work screen and preferences screen
I have a new Mac Pro
Mac OS Catalina 10.15.4 - RAM 32 Gb - AMD Radeon Pro 580X 8 GB
Common problem when you do a lot of brushing on an image; made worse by
4K or larger monitor
turning on masking
large megapixel originals
slow CPU
If you can do this type of brushing in Photoshop, then you should do it there, you won't have these problems. If you have a 4K or larger monitor, you can try as an experiment replacing it with a 1920x1080 monitor. IMHO, Lightroom Classic is not an effective tool if you need to do a lot of brushing and you have a 4K or larger monitor and any of the other things that make it worse.
