HELP: Filters affecting full image instead of only the selection?!
Hi everyone, this is a serious problem for me as it just stopped me from being able to do anything with Photoshop! I have never seen anything like this and wonder if there's a simple solution for this?
Basically, I have an image and I want to create a selection of it then applied a filter to that selection. Be it a filter or any color adjustment - whatever I do it affects the full image and changes don't stay constrained to the selection!!??
This just started happening in the middle of editing an image and now it works the same way with all images, even after restarting the whole computer.
I'm using Photoshop CC 2020 on a Macbook Pro. Never seen anything like it and it's driving me crazy!
Any help in resolving this is greatly appreciated!
