Thanks for the reply Chris, however i am trying to find a way to shall we say 'cancel out' the existing background not 'cut it' out, the images i am working with are very complex and have several areas where the foreground image (the part I want to save) is translucent enough to see the background through it. that's why neither the magicwand cutting or the painting an outline around the foreground methods described in both of those tutorials will work for me, i was hoping to use the 'clean' background image i have as a layer to have it shall we say 'strip' itself out of the main image, leaving a foreground image that has the areas where the background didn't show through as full transparent and the areas where the background did show through as translucent areas. I was hoping i could achieve this by setting the blend modes of each layer to some specific setting like multiply or something maybe (i don't understand enough of how all the different blend modes actually interact with each other to do it myself that's why i'm asking here). I do however thank you for taking the time for trying to help me, I just wish it was as simple as using one of those methods.
Thank You,
