It seems like the first idea was the simplest. Put a one square foot piece of
cardboard on the front of the grill. Take a head-on picture, then draw a grid
using the four sides of the known dimension. calculate from there. Yeah, how
wide an agle lense you use, and how far away your phtotp is taken from will
have a miniscule effect on the final outcome, but probably not enought to worry
about. What's wrong with that idea?
