Preparing Anime/Cartoon Caps in GIMP (Including imitating PS's High Pass filter)

[hophopicon]

This is my first tutorial! I am terribly nervous about it!

Today I'm going to teach you how to go from this cap (by ohlookcaps!) to this! Note that the end result of this icon is quite saturated, but that's not necessarily the end result of this process.

Program: GIMP, shown on a mac but it should work absolutely the same way on a PC.
Translatable: Yes,
