Hi Chuck,
There are a number of constraints when trying to display images on line.
The camera delivers 240 pixels/inch, getting close to your target of 300,
but, if when I tried to display a large image on the LUG gallery, I
encountered the gallery-imposed limit of 10MB per image. I reduced the size
to get below that, but left the resolution at 240. On my Epson R800
printer, I can only go up to 8.5 x 11, so it is not worthwhile to try a
print to prove anything.
However, when I display this latest TIFF image to my full screen size, I
can't discern a fall-off in definition in the area of the original image I
displayed.
