Magic? Quite possibly. Check out this neat app called Page Layers that pulls in a website and spits out a Photoshop file.
To be honest, this technique helped me learn how to do most of what I know how to do today. In other words, I would look at other people’s work and see how they built things and then learned from copying strategies and methodologies. From there I was able to build my own foundation and technique.
I doubt Page Layers pulls in the designers exact layering but the idea is to see how it’s put together and such. Could save you some valuable hours if you’re reconstructing an existing page or learning to do it yourself.
Why not? If you get some Christmas and holiday money, it might be well-spent here.
