I need to cut into a mask to reveal a layer. I have a alpha image with thousands of lights scattered around the image. I'm laying the lights layer over an image of a city to create more lights in various buildings. All I need to do is create some form of mask that when I cut into it reveals the lights below which is over the city. It's a basic question but I'm stumped. Thanks peeps.
Hi, Jps, if the lights are on a black or dark layer, it seems like it is a job for one of the blending modes from the screen & lighten group, and no need to create a Mask!
Thanks to both replies. Both helpful thanks
