Well, they wouldn't be secrets then, would they ;-) Broadly it involves multi-exposing at different apertures and focus points and comping together using the lens cast compensation software in the raw file development. It's also true to say that I don't have a need for focal lengths greater than 150mm so I can't comment on what you say about 600mm macro work. Come to think of it I don't recall ever shooting at that focal length when 5x4 was the name of the game. The rail would have been extremely long. > You need a good lens to use 80Mp in 16 shot, and for macro on a 5cm * 4cm > CCD, you would get no DOF.

A 16 M pixel file can deliver a diamond ring 20x magnification at repro res and clearly resolve the tiny inclusions that jewellers prefer you not to show. Single shot mode is entirely adequate if not over kill in 99% of cases. Looking back at the scans from old 5x4 shots, I'm appalled at what I accepted as good then. The 210 Symmar bolted to my Sinar is a peach of a lens but it doesn't begin to approach the resolution a Apo-Digitar M can deliver. As I said, the level of the bar has been raised by digital.
