How do I add multiple masks to a layer in Photoshop CS3? I already created one mask for chain link fence so that the fence would appear between a person and his original background:
Now I would like to apply a second mask to the chain link fence for dirty grunge effect - for example, make some chains broken or frailed. The reason why I want two masks is so that I can edit each independently and have a non-destructive way of playing with my fence.
It's hacky, but you can add multiple raster masks by Grouping the layer. Of course, this may cause problems if you need it to be bound to a lower layer, but if the layer is "independent" you can add as many redundant masks as you want.
So, in your example, you could make your fence with its layer mask. Then make a group with the fence (and any effects). Mask the group with the man's outline so the fence appears behind him.
