Circle of Least Confusion?
-
In a 1951 photography book that I have what is the meaning of the ‘Circle of Least Confusion’ :
a. a photographer spinning too an exact point were heshe is confused as to what I am doing here?
b. the image formed by the lens of a point of light, is never quite a mathematical point, as it would be with an absolutely perfect lens, but is instead is a tiny disc of light.
c. if a pencil of light from a point source after passing through a lens does not converge to an absolute point.Hi Polmac,
I dont know about back in 1951, as Im glad to not have been around then, but these days, its the smallest point/disc of light that a lens can make, given that only a perfect lens would make an exact point of light.
Hopefully, what you were looking for..
Alan
