From a total of 8,222 digital photographs in my collection, spanning 1997-2011, all photographs where the sky took up more than 50% of the image were pulled.
The resulting 358 photographs were processed using custom-written software that read the RGB color value for every pixel and wrote those values to a text file. This file was then used in conjunction with a second piece of software to rebuild a single image, containing every pixel from the 358 photographs, sorted from black to white — a total of 42,607,656 pixels.
