Hi, welcome to yet another novice tutorial containing very basic prep steps in Photoshop, which must be done at least once in a lifetime. Otherwise you'll miss a thing. Or two ;)
This tutorial is dedicated to creating a custom brush preset of a grass in Photoshop, which might be easily used to recreate lawn/meadow edges without any effort. Once the brush is created, you can save it for later use and use it whenever you want to!
First I wanted to get out and take my own photos, but when one finds out he doesn't have to even stand up a walk away from the computer... life suddenly gets easier. For this tutorial, I decided to use some free photos from rgbstock.com - check out this Tuft of Grass and this photo of a Castle in Sucha. It only requires a free registration and you can get these photos immediately.
