Adobe Chief Technology Officer Kevin Lynch demonstrated some ideas last week at Adobe's Max conference using first an Android-based Samsung Galaxy Tab and then an Apple iPad.
In the first demonstration, he showed Photoshop's content-aware fill technology that can add some smarts to the deletion of phone lines, ex-boyfriends, or other elements of an image. He used his finger to paint over an image of a grouse against a green field. After a few seconds of processing, the app filled in the area with more green grass.
In the second demo, he used an iPad app to mix colors with a virtual palette then, select them, then finger-paint on an image actually hosted on a copy of Photoshop running on a linked conventional computer.
