paleonet Digital photography again



Yes... but the biggest advantage to going digital is that I can shoot as many
images as I want in the field with not a care about expense of developing the
film -- and more importantly I don't have to wait until the image comes back
from the developer to find that I screwed up a shot that at that point cannot
be replaced.

As to the resolution argument I think that Stefen covered it quite nicely in
one of his postings.

"600 dpi is overkill for most or all publishing purposes - an image of
1800 pixels' width can easily be printed at 6" width (at 300 dpi).
But then you normally would like to have some margin, in case you
want to blow up details of the picture."

There are not too many journals out there that I know of who print 11X14"
images.

Additionally in many cases interpolation is not all that bad for lower
resolution images.  As a test I sent in a relatively tiny 490k image to
www.shutterly.com that had been cropped to 70%.  I ordered up an 8X10" print
and it looked great.

My Pentax SLR film camera has not been out of the drawer for over two years
now and it looks like it is going to stay there for good.
