It's a wee Canon point-and-shoot thing - an A650is, chosen because it uses AA batteries which I figured we'd be able to get anywhere in the world. In fact, before we went, I bought the local Tesco's entire supply of Lithium AAs because they were half-price. I took about ten packs with me, but only had to change the batteries once despite heavy use of the playback feature.
We set it to 80 ISO, and the mode button was glued in the 'P' position, so we just pointed and pressed. No skill or technical intervention required!
