I have two Ps question, please answers them. 1. In Ps, is there the ability to make a color transparent(like in GIMP, Color to alpha). 2. Is there a way to add pictures as layers(like in GIMP) to same project, e.g. Take a pic and add second pic to change background. If Ps is the number 1 image editing program, does it have these abilities??? Any help would be appreciated, then i can finally uninstall GIMP.
