Arduino project lend themselves very well to the world of photography, for example remote shutter releases, intervalometers, and so on. Another great use has been demonstrated by Arduino forum member "mitchrichie" who has modified some servos to continuous rotation and used them to move a DSLR camera along a slider track. This would be useful for stacking-focus photography, observation and also various directions in video. The slider is demonstrated in the following video:

If you found the project above interesting - but not sure how to start with Arduino, then the best way to learn is with our Experimenter's Kit for Arduino:
The package includes a wide variety of parts, sensors and modules including: a servo motor, lights, buttons, switches, sound, sensors, breadboard, wires and more. Furthermore a Freetronics Eleven Arduino-compatible board is included to make this an extensive hobby experimenter, inventor and starter kit. However we don't leave you alone to figure it all out, included is a great project and instruction booklet, plus access to a supporting web page and software examples. In other words - this is everything you need to get started for a fun range of electronics and Arduino related projects!
