In this example I have access to tools that aren't even in Photoshop yet; Liquify facial recogonition for editing purposes.
The Liquify filter in Photoshop and PS Fix can do some pretty funky things to a picture, but my concern is in it's more practical uses - in other words, good old digital plastic surgery. And to ensure I offend no one but myself, I will only use photos of me in this project.
I have a shot of me, taken many moons ago and while it's a decent pic, direct flash tends to flatten contours and as a result, make a face appear a little - umm - wider.
In this example, I accessed the photo from my Facebook account, directly from within Fix. I did this by clicking the "+" icon on the left of the app, and choosing Facebook. If you've never done this before, you will have to authorize the app through FB first.
