How to shoot super detailed macro photographs with the help of an Arduino and a bunch of LEDs

This is one of those topics that can become extremely complicated very quickly, but if you have a love of macro photography and a passion for electronics, this could be just the project to get you fired up.
Using a process called “Reflectance Transformation Imaging” (RTI), whereby light is studied hitting the surface of an object from multiple angles to produce a sequence of images, we’re suddenly able to see a lot of detail that would otherwise be missed in our normal macro photography.

The process is a fairly simple one to describe. Have your object and camera in a fixed position, and photograph it a whole bunch of times using multiple light sources coming from different angles, in order to determine what direction different parts of the surface are facing.
The resulting images are ran through a piece of software, developed by a number of researchers and host …
