My iphone never ceases to amaze me. I just pulled up the app store for a quick break and it recommends this program "Auto-Stitch". Auto Stitch does exactly what it says... stitches together photos in your iphone to make one big composite image.
So I fire off a few shots (no tripod, as you can see in the less than flattering reflection), open the program, choose the pictures, and it goes to work. 20 seconds later I have a nice composite that it lets me crop into a panorama. I didn't even make an attempt to hold it steady or maintain the same distance to subject.
If I'd wanted to, I could have also run noise removal ("Noise Blaster") and done a few color corrections ("Best Camera"), but I've got to get back to work. When I was done, I launched the Flickr app and its out on the web. Start to finish took less time than it took for me to write these two paragraphs (and I'm a pretty fast typist).
If my iPhone camera were any good, I'd leave my nikons at home!
