So this is my first tutorial. I kinda liked this effect and I wanted to give back to this community so I thought I'd give it a go. Okay, we'll be going from this to this. I use Photoshop 7, but I'm sure its translatable. I hope somebody finds this useful.
Made in Photoshop, but the first part only involves flood layers so it can be done with any program. The second part invovles selective colour so it can only be done in Photoshop. It's nine steps total.
