Re: [Leica] Digital Truly upon us?

Is it so evident that resolution really affects the _structure_ of scans? I
think what reddawn was saying was not that 2900=4000 in terms of res, but
that he imagines that the problems he experiences are unlikely to go away by
just increasing the scan res. For instance, the problem of grain breaking up
the colour structure of film. Supermagnify a colour neg of the sky and you
get lots of little dots of various colours; supermagnify a digital camera
image and, it seems to me, you get a load of pixels, all of the same colour.
So digital capture is bound to be structurally very different from scanning
in this sense at least.
