Shift Channels --> Alpha from Luminance
Levels --> Clamp away outside areas
Layer blending mode set ot add, replacment layer below it.
Hi, thanks for your response. Im going to try it out and see how it goes. When you say clamp away outside areas do you mean delete?
No, you simply adjuts the black and white points to eliminate all shades of grey up to a certain point. Extracting the luminance will naturalyl give you some random areas outside the pages( photo as well and this will get rid of them mostly. some basic rough masking may also do the trick...
Ok I'm going to try it later cause I'm off to bed for now. The only thing though, when I try applying a mask to the layer before or after applying the effects you suggested it doesn't allow me to. The mask path is visible but it doesn't do no masking. Any idea why is this?
