That might sound like a oxymoron, but I believe the term 'photoshopping' turned to mean manipulating photos (with or without Photoshop).
I'm especially interested in realistic effects on faces, like smoothing skin, whitening teeth, and so on.
The main issue in Photoshop is basically their price model (pay and pay monthly, no matter whether you use it or not). I want either a pay once alternative or open source/free.
