This was an attempt at double exposure with layer masks - it did not turn out quite how I'd hoped and I had to leave the background in around her head as the superimposed image did not stand out enough to be discernible otherwise. Nothing new here, both are old photographs, but having missed a few days thought I ought to put something up. No need to comment, just one of my (slow) learning curves:)
I've been trying to do in camera double exposures. Easy when using average, but experimenting with light, added or dark. Still don't have that sorted. This looks pretty cool.
