OK Simon, I decided to play - sort of.
The following is a link to a 3076 x 2052 image shot with a Canon 10D (6mp),
in RAW format, converted to a TIFF image, down-sampled to 899x 600 in
Photoshop and then saved as a JPG.

Here is a 100% (unsampled) 468 x 468 crop from the bottom right of the
original TIFF image, saved as a JPG.

And, here's a 372 x 372 crop from the top center of the image:

For people other than Simon that may not be accustomed to viewing images at
100% on a monitor. The image really is sharper than it looks in the crop
because what you're seeing would make a very large print if printed at the
same scale. For example, if you're viewing the crop on a 15" monitor
running at a resolution of 768x1024 then the crop is the equivalent of a
~25" x ~37.5" print. (I'm sure someone will check my math and let me know
if I miscalculated.) :-)
Simon, others - feel free to right click on the above images and download
for your own experimentation.
Later,
Johnny
