Sadly the big problem with Luminosity channel in LAB is it is a very coarse
control.
Incredibly, in Adobe's infinite wisdom (similar to the fashion that PSCS is
the first product to fully support 16-bit operation throughout, as far as I
understand it) the L channel operates on a scale of 100,

Well, I do not own that camera and am not familiar with it; but I assume
that if you look in the manual you will find that you can capture your
images at around 300 dpi and save them to a tiff format; but capturing them
at a high resolution around 300 dpi as a RAW file would also be good, as

The dpi setting of a digital camera file is utterly irrelevant here.
Different cameras output their files (no matter their format) at fixed dpi
settings. Different manufacturers of digital cameras have different norms
for dpi, but it has no impact whatsoever on resolution or print size.

I beg to differ with you; but I am not going to get into a food fight with
you over it. In the case of RAW, you are correct the dpi is somewhat
irrelevant in that raw files do not contain any reference to resolution per
se only to the size of the image X x Y pixels; however, if you save to a
Preston, technically you are correct in saying failes do not have resolution
and even in saying that their contents do not either; but standard non-RAW
file formats do contain metadata which furnish rendering instructions which

Put simply, you're confused by the way that certain software applications
(e.g. Photoshop or scanner software such as Nikon View) allow the user to
specify the pixel-dimensions of a destination image by specifying dpi and
linear dimensions (in units that are not pixels - e.g. by requesting an 8
