I started to make Photoshop brush sets here on BittBox many years ago, and everyone seems to love them, so I'm gonna keep sharing them whenever I can. I actually took leaves from my own back yard and scanned them to make this Hi-Res Photoshop Brush set. There are 10 brushes in the set, and most of them are 2500px in size.
A Closer Look:
The image below is a clipped section of one of the brushes at full size.
1. Download the file and unzip it.
2. Copy the .abr file to your Photoshop/Presets/Brushes folder.
3. In your Photoshop Brushes palette, click on the arrow in the upper right and click on “Load Brushes.”
4. Navigate until you find the file and load it (Photoshop/Presets/Brushes/BB_HiRes_Leaves.abr )
Note: The next time you restart Photoshop you will not have to load the file, it will be in the list of Brush Libraries.
