It's Not Perfect, But It's Still Pretty Cool
I'm a regular reader of Lifehacker - a blog about 'tech tricks, tips, and downloads for getting things done'. There was a post last week about stitching photos into panoramas with a free program called Hugin.
I took a few pictures on my run in Central Park this morning and put together a panorama of the Reservoir. I didn't have time to make it perfect (matching exposure, for example), but I think the results are cool all the same. The panorama is an assemblage of 4 photos - three of which are blended together seamlessly.
The software seems pretty easy to use and should be even easier once I have time to read the instructions! The lifehacker post has a good walkthrough of how to put together your own panorama in Hugin.
