Yay for Cropping in Photoshop CS6!
If you've been looking for a reason to upgrade to Photoshop CS6, the new cropping tool may be one of the biggest reasons to consider it. The cropping tool is now NONDESTRUCTIVE and works pretty much like the cropping tool in Lightroom. Once you press the key that accepts the cropping, the cropped pixels are not discarded but rather are simply ignored, but retrievable if you just re-crop. Fantastic, but that's not all. Notice the way the interface now executes a crop — by showing the cropping frame in the context of the full image. Look familiar?
As you crop, the full image is still visible and the image rotates rather than the cropping frame. Sweet! It's about time Grandpa Photoshop learned this slick trick from Lightroom.
