Must have been Lifehacker that recommended MIcrosoft’s Image Composite Editor, to put together panoramas of photos. They said it was pretty good, so I downloaded it.
I thought it was going to be somewhat tricky to use, trying to figure out similar points in the photos. And then I was worried about the different angles of the pictures, that it would look weirdly bent.
But, nope. No worries. The program does everything for you.
