Looking from that distance at a print that size would mean you could not take in the whole area of the picture without scanning it with your eyes. This factor is one of the things that annoys me about a lot of photo books. They are very often far too big to be able to see the whole picture comfortably at a normal (for a book) viewing distance. -- Cheers, Bob > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On > Behalf Of Patrice LACOUTURE (GMail) > Sent: 26 June 2006 01:50 > To: Pentax-Discuss Mail List > Subject: Re: Print sizes and megapixels > > Hi, > > On a purely theoretical point of view, the human eye can > resolve details > at least 1/60th degree wide.
