Digital BW, The Print

I liken this debate to the one that went on in the audio world some 
years ago. Studies showed that the human ear is not capable of hearing 
differentials more than 8 bits. They also showed the human ear is not 
capable of hearing frequencies below X and above Y ( forgive me I don't 
remember X and Y and their values aren't important).

This experiment was repeated many times with the same results. However, 
if you filter music so that no energy from frequencies below X and above 
Y appear and run a test to determine if people can hear the difference, 
they sure can. If you run test todetermine if people can tell the 
difference between complex music sampled at 8 bits vs. 12 bits, they 
sure can. In fact music sampled at 8 bits and limited to frequencies 
above X and below Y sounds pretty "hollow." It gets to the fidelity of 
the reporduction.

I think the same is probably as true for the eye as is for the ear. 
 While humans are not suppose to be able to see beyoun 300 dpi, I would 
expect in a complex image they sure can tell the difference if it were 
printed at 300 or 360 or maybe even 720.

I always down sample to 720 and print from there.
