Let's say I have a picture: black lines on a white background. I can select all the white parts with color selection. What I need is to have every continous selection moved to a separate layer. Can I do this automatically is Photoshop? In this example above, I want to have 7 different layers with the seven "tile" without having to select all of them one by one and create a new layer from it.
I realise this question is ancient, but this might be useful nevertheless if someone comes here to look for a solution. This isn't "automatic" - but not exactly complicated. A few mouse clicks and you'll have the job done.
Use the Magic Wand Tool, set to "Contiguous" in the tool options.
Make a selection, then copy and paste. The result is a new layer.
Select the original layer again.
Repeat steps 2 and 3 until complete.
