Janine Smith on Tip Squirrel has a nice post on the Photoshop CS5 Content Aware Healing Brush, a new option in the Spot Healing Brush. The picture shown above took 30 seconds of work:
"In a way, Content Aware Healing brush is Content Aware Fill’s little brother. Not the brainier, scrawny little brother, just smaller. If Content Aware Fill is the Army, taking out unwanted big areas in a single (or double, or triple) bound, the Content Aware Healing Brush (CAHB) is Special Forces, conducting specialized operations in tight places where Content Aware Fill (CAF) might not work so well.
Even in more concentrated areas that CAF works in just fine, CAHB is just easier simply because instead of repeatedly selecting and bringing up the fill dialog is replaced by marking the area you wish to heal – cutting down the amount of steps you repeat to complete a process saves you what? It saves you time. Again with the time! But, remember, time savings is my #1 reason for loving Photoshop CS5! Sometimes, on the other hand, CAHB might take a couple more steps, but the result is worth it.
Also, check out Content Aware Healing at NAPP's PS CS5 Learning Center which compares the new option with the older Spot Healing options. Here's another take from Martin Evening and Focal Press, Photoshop CS5 Content-Aware Spotting and Filling:
