is a $3 app that stitches together a series of shots you take on your iPhone into a panoramic photo. Not only is it quite convenient, but I get a smug sense of satisfaction from stitching together panoramas on my phone without resorting to any software on the PC.

won't cost you anything, and it includes 2GB of free online storage for your photos. Editing tools include cropping, exposure, and artistic effects.

And finally, do you use Flickr? Then the free is one of your must-have apps. Not only can you browse your own photos, but see images from the rest of the Flickr community as well.

I've recommended using a tripod many times before, and sometimes I worry that I sound like a broken record. In response to that, readers often complain that they don't want to use an expensive, heavy tripod just to take sharp photos. The good news is that you don't have to spend a fortune or carry around a 30 pound monstrosity to get support.
