Google+ just got some pretty cool upgrades to its photo management toolkit. It can automatically enhance photos by adjusting brightness, contrast, saturation and other factors. It can animate a series of photos that you upload, or stitch together family portraits and panoramas from a series of single images. Thumbnail strips highlight your best photos and de-emphasize (fade out) any duplicate, blurry or other poor images. And Google+ offers free automatic backup (up to 15 GB, shared with your Google Drive and Gmail accounts) of images at full resolution. Or you can back up an unlimited number of pics at standard (2048 pixels) size.
