Re: filmscanners: Filmscanning vs. Flatbedding

If you (John Brownlow below) could talk in terms of digital imaging 
terms, maybe I could understand precisely what you are talking about. 
The word "tone" means almost anything, depending on the background of 
the individual.

What I would like www.robgalbraith.com to post is the gamut breadth 
and fidelity of the DCS 760. Tone to me is gamut accuracy (meaning 
chroma and hue angle). But more than that it is the ability to 
accurately capture "chromas" and "hue angles" at resolutions that 
match the best film recording media; i.e. Ektachrome, The gamut 
latitude of Ektachrome exceeds that of all negative films (the last I 
checked), but I don't know where this digital camera stands in that 
regard. And accuracy, pixel by pixel is another matter. So, what can 
the DSC750 do with gamut latitude. gamut accuracy? Nothing seems to 
be ever posted about this.

Also, unless a digital "picture", or scan is shown in direct 
comparison with its competition (meaning film in this case - not 
another digital camera), one can't come to meaningful conclusions 
because the eye is easily seduced into thinking "that's a really 
great picture". There must be side by side comparisons. That is the 
convincing hurdle to cross.

And of course, the film scan, or Ektachrome scan must be first class, 
so that the gamut of its image is completely captured. And this 
requires a pretty good understanding of scanning techniques, and 
color management, measurement, and control. Not a small undertaking. 
Since the DSC760 avoids the scanning process and the uncertainties 
and errors of color management in scanning, it has a leg up in that 
regard. Maybe.

Yet to be convinced. But open to hard information. -
