Hello,
I am trying to find out the best way to remove the sky from the background here (Including all of the little spaces between tree branches)
The Cutout Lab doesn't seem to work for how intricate the selections are. All help is appreciated!
I did this with the Color Mask in 4 clicks (blue sky, plus three cloud areas) then a quick clean-up of where the mask had been applied to parts of the buildings. Last step was just to do Mask Outline > Feather 2px as the color mask doesn't have any anti-aliasing or feather settings.
