How would i create these textures?

Hey guys, i have been taking photos of my own textures lately for my game. I want to txture the leaves of a tree, and the texture of grass strands (for billboarding). How would i make or find textures to do so?
And also where are some good texture based tutorials for photoshop?

Thanks alot in advance

You can’t just learn a specific function of a graphic manipulating program, you need to know it inside out thoroughly as a lot of their functions are related. So get a book and start reading.:yes:

My advice, take a photo, have another photo next to it,
and a blank(transparency) file.

use clone tool to move something from 1 image onto the (transparency) file.

this is a alpha map :smiley:

another thing, Gimp is free and GPL :smiley:
