One of the difficulties of working on a very small scale with a very cheap webcam is that I don’t have a great deal of control over depth of field. A lot of the time, I’ll abandon a more ambitious, interesting-looking composition because it’s just not possible to have all the key elements in focus at the same time.
Today was one of the rare occasions when I got to cheat. After some false starts yesterday, I decided to take a static shot of passengers enjoying an awesome train ride and add some digital steam to give the impression of motion. As ever, it was impossible to frame the shot the way I wanted because of the depth of field problem.
So I took 6 separate photos of the same scene, changing the focus each time, and merged them all together into one image. It looks pretty good, I think.
