Re: Enlargement factor has been ignored

If two sensors are the same size, but one has more pixels than the other, there's some probability that sooner or later, the guy equipped with the higher pixel count is going to make a larger print than the guy who has the lower pixel count on the same size sensor. Using the higher number of pixels on the same size sensor to produce a larger print causes the Airy disk diameters at the sensor, for any given f-Number, to suffer more magnification in the final print than they would in a smaller print, and thus a greater likelihood of diffraction inhibiting a desired print resolution. The photographer has to shrink the Airy disks at both the sensor and in the final print (after enlargement), by opening up so that his desired print resolution is not compromised by the larger Airy disks that come with the greater enlargement factor.

Beating the dead horse...

Do you really think that airy disk reveals itself on the print (final of course) as disk?
