So - 3 layers: 1.Background, 2. house and 3. palm tree.
Lets say that I now want to paint the house blue and still have the palm tree in front of the house in its original colour.
So this is what I do:
1. I make a selection of the house by selecting the layer with the house (so now I have marching ants around the house selection).
2. To subtract the palm tree from this selection I now hold down the Ctrl + Alt keys (on my PC) and click on the small thumbnail image pertaining to the layer with the palm tree...
And this is where it all goes wrong (intermittently 50/50%) - it subtracts the palm tree from the selection as it should - but 50% of the time the view will zoom in on a completely irrelevant area of the image, right down to giant pixels showing - while at the other 50% of the time, it will zoom right down on the palm tree. (Which is actually really annoying too!! - because I have no intention of working on the palm tree. And I am told by Adobe that this stupid auto zooming cannot be switched off in version 2020).
Because of this "...zooming in on a completely irrelevant area of the image, right down to giant pixels showing" I have now had to revert back to Photoshop version 2019 to be able to do my work.
PLEASE Adobe - make version 2020 a functional version.
