I recently moved from a Canon 1Ds3 to the 5Ds as my main camera and wondered about printing the images. Although not the biggest part of my business, architectural print sales do matter, so I was interested to see how I might need to change my print workflow for the bigger files.
Having made steps from 11MP to 21MP to 51MP over the years, I thought a simple print test would show the massive improvements since my first Canon 1Ds
Sure, the differences are there (of course...), but the real surprise came when I asked some non photographers to compare the prints.
If ever there was a reminder that what we sometimes think of as important doesn't matter one jot to (most) people who actually buy stuff, this was it
From my own POV all that extra detail is excellent - it's not what sells though
