Man you have to read the whole thing.
Trust me ... I did, several times.
As to the white square / black wall ... I'm still trying to figure out how both you and Neil Armstrong can take a picture of the moon in accordance with your theory regarding ISL @ camera to subject distance.
Let's see, Neil is shooting from 5 feet away ... we are shooting from (238,900 x 5,280) 1,261,392,000 feet away.
By my calculations 2^30.25 = 1,276,901,417 ... suggesting that the illumination falling on Neils camera would be 30 stops brighter than that which falls on ours.
