By camera phone - Part X
The decorative pattern on a wall. This shot was taken just outside Citypoint, which is near the Moorgate tube station in London.
I've found that the Sony Ericsson K800i is very good for these kind of impromptu shots. You don't go out deliberately to get a shot like this. It's completely random while walking on the street. Having something like this in your pocket allows you to never miss a good opportunity.
On the flip side, I do find the lack of optical zoom to be a bit restrictive (there's 16x digital zoom of questionable quality). I often see something in my mind's eye, but am unable to frame it properly without more reach (you can't always go nearer to the subject).
