More advanced photographers often find the need to accomplish “focus stacking” – the process of taking multiple images at different focus distances to give a result with a greater depth of field than one image of the subject. “Really Small” on flickr found the need for their own focus stacking controller, and has documented their own version – by modifying a manually-controlled stacker with a stepper motor. The control is via an Arduino and related circuitry, housed in a professional enclosure:
When reproducing this project, you can save time with out Freetronics Eleven – theArduino-Uno compatible with onboard prototyping space. For an LCD module, look no further than our LCD & Keypad shield:
