Leaf

imported the image of a leaf into photoshop, then used the magic wand tool to cut out the leaf

followed by adding another layer, then filling in black around the leaf
then adding another layer and filling it in white

importing the lead into 3ds max studios material editor, removing the white background with the black and white image by adding it to opacity, then adding bumps to the leaf for texture

then adding the leaf to a plane to bend it into a 3d shape
