I am a novice.
I have been using the File, Place tool to place fairy wing overlay document png type (invisible background layer) files over background images, and then using the erase brush tool to clean up (erase the overlay) from the face and chest area. Its worked beautifully for days, but today it does not work for me, and I can't figure out why its changed? I did notice the assistant started coming on, with notes about rasterising the layer, but I selected to undo the action, and the assistant is disabled. I thought this would stop my issue. I think I want to be able to erase from a vector layer freely....
So, my process has been to open my picture, place my png overlay, and erase any "interference" over the subject's face... in PS I learned only briefly to use the paint brush tool to paint the overly in black over the overlay to "reveal" the area underneath, but that technique is not working either....
Thanks,
