I used the image from a cam and for each image I ran through the pixels, line by line, and averaged the luminance of all the pixels. The images were taken every minute, so I could develop a daily chart of the amount of light within the cameras view. Didn’t have access to a simple ambient light sensor, but this worked quite well.

I am intrigued by the possibility of re-appropriating data to understand some unintended perspective.

Interesting recent book from O’Reily:
