When taking macro photographs you lose a lot of clarity due to a reduced depth of field. One way to get sharp pictures is to take multiple shots at slightly different distances from the subject and then stack them into one image. There’s software to do this for you, but you still need a set pictures to start with. [Dsvilko] built this setup to easily capture a set of macro images.
He’s using the internals from an optical drive as a sled to carry the subject. A PICAXE drives the stepper motor that moves the carriage, which takes input from an IR remote control. This turns out to be a fantastic method as the sled can move in 0.2mm increments. After he’s got his set of images he uses Zerene to stack them together.
Bonus points to [Dsvilko] who used Linux command line tools to edit together the demonstration video embedded after the break.
