[Award Winner] Local-scale tree texture in Photoshop CS3

[Normski]

Very nice, smooth and very easy to follow. I will be using this again!

Update: I changed a step. The original tutorial on Cartotalk required use of the grain texture, but equivalent results can be obtained with the noise filter set to monochromatic and about 1%. This eliminates the need to change the color space and allows the technique to be used at any point in the image creation instead of requiring that it be done at the beginning (or pasted in from another document).
