Discovered it by way of doing research on Jerry Garcia. I'm impressed by your intellect and breadth of knowledge/interests/abilities. We share a lot of common ideas, interests and tastes. I did, however, run this last blog by my mathematician/computer scientist husband Jeff who found this glaring error. You wrote: The web convention is to use zero as the minimum brightness for each pixel and 255 as the maximum, giving 256 possible values. 256 might seem kind of random, but it’s a nice round number in binary, two to the sixteenth power, so it’s convenient from an engineering perspective. According to Jeff, it's two to the EIGHTH power, not sixteenth. That would be far, far too high. Sincerely, Leah (no website) I’m really enjoying your blog.
