Left - unmodified, right - modified

So from what i'm understanding, in Photoshop, you have to use one of the selection tools, then right click your image, click Free Transform, then set the height percentage to 87.5 (25% of 100) or possibly, but untested, 75.0 (50% of 100), and set the horizontal skew value to 5.0 degrees
Then your face should appear mostly normal when you use it in BattleBlock Theater
I'm not sure if it varies from image to image, but these are values i've been using, and so far it's kinda worked
The most helpful guide is the one by
Ricka and Booms, but they say don't know the ratio for skewing, so do you think i should post a guide for Photoshop users? :o
