i downloaded a couple photoshop brushes. specifically realistic looking things like scotch tape etc. when i paint the scotch tape brush on a white background it looks perfect, however the actual brush itself is opaque and a bit transparent. if i were to try and paint this brush on a colored background the effect would not be as good as it looks on a white background. how do i merge the brush and the white background so that i can move the scotch tape onto another image? i dont want to move the entire white background, doing so would just look like a huge white square, i only want to move the part of the white background that is giving the transparent scotch tape some color. using the magnetic lasso tool is not an option because doing so removes some of the shadows and details of the brush. ccan anyone help?
