You can do this by flood filling the mask with a black-white gradient. Black areas will turn the underlying image fully transparent, white areas will be fully opaque and shades of grey will be degrees of transparent.īecause you want your image to be transparent at the top, the mask needs to be black at the top. the pixels on them can be black, white or any shade of grey. If you look in your Layers palette, you'll see that the mask layer is shown as solid white.
Open your image and go to Layers > Mask Layer > Show All. Mask layers control the transparency of the underlying layer.
