How do I delete all white pixels from several layers?
I have a photoshop file with over a hundred layers. Each of these layers have white backgrounds. I need to remove all of these #FFFFFF pixels automatically. I'm not worried about the actual content being deleted or anything. None of the content contains any pure white pixels.
You'll have to remove the white layer by layer. There's no automated processes to strip white from all layers.
If it were me I'd probably use
Select > Color Range to grab the white on each layer, then add a mask, repeat for each layer.
