I believe the super-duper very high upper crust end of digital can get 8x10's using their highest possible resolution, but 11x14's are too much of a stretch, especially compared to what you can get from medium format, even a 645. There are very sophisticated algorithms now to increase resolution for printing, but regardless of how sophisticated the mathematics are (including the fractal stuff) they cannot add details from the original scene that are not in the original digital file.

IMO the acceptability of large 11x14 prints from digital cameras is resulting from the "dumbing down of the herd of the average viewers" who are now accustomed to the softness of low resolution television, nearly as low resolution and grainy computer screens, and have never seen what can be done with film, especially 120/220, if it's done correctly (not APS from a 1-hour drugstore lab). Hang an 11x14 from a digital camera next to an 11x14 print from medium format shot and printed properly, and there should be a visible difference between them at close viewing.

John,

I agree if you bring 645 into the mix and is optically printed, but there is something going on with perception that I do not understand. It looks like digital image processing is replacing optical/chemical printing. You would think that a high quality piece of film of 35mm, or even 645 scanned at the same resolution as an image recorded digitally by a CCD would look the same, but the CCD image usually looks better. Scanned film file sizes seem to be much larger than equivalent appearing images taken with a CCD.

I am not sure what that is about. Since you can continue to see subtle improvements increasing resolution of scanned film from 4000dpi to 10000dpi I thought it would be a long time until digital cams could stand beside film cameras, but now with this apparent acceptance of the eye for printed CCD images I am not so sure.
