Justin Mason posted how to solve a maze with Photoshop

‘lod3n’, confronted by this heinous puzzle, wrote:”2 minutes in Photoshop. All too easy. So, where do I pick up my cake?”

1. Increase contrast.
2. Select the right wall of the maze using the magic wand.
3. Select > Modify > Expand 4 pixels
4. Create new layer.
5. Fill with Red.
6. Select > Modify > Contract 2 pixels.
7. Delete. Now you’ve got a line tracing the solution.
8. Manually clean up the outer edge, and connect the dots.
9. Cake!’

Here’s the result. Seriously nifty!

I’ve tried this on a number of puzzles and so far its worked on every one. Another option would be just stroking the selection directly after doing the expand, and then cleaning that. In Gimp just use “grow” & “shrink” selection.
