You might have heard Photoshop CS5 has an exciting new tool in the works that promises to save vast amounts of time and effort. It's called Content Aware Auto-Fill, and you can use it when you want to edit out unwanted items in a photo, such as lens flare. You simply circle the article you want removed, hit Delete with Content Aware Fill, and presto! It will remove the offending object AND automatically fill in the background so that it matches perfectly. One of the product managers at Photoshop posted a quick tutorial here a few days ago that shows how it works.
A joker named Matt posted his own Youtube tutorial [above] revealing some very practical applications for this new tool, and demonstrating its awsome progressive learning capability.
