[Rhodes22-list] slides vs digital camera

David,

I agree there is no intrinsic technical barrier to making a truly rugged,
water resistant digital camera.  However, it is not something the average
camera owner can do with an existing digital camera.  The available housings
for converting standard cameras for underwater use render the camera truly
clunky & unwieldy for most outdoor uses.  All I'm saying is that the major
digital camera manufacturers haven't yet offered an easy-to-carry,
point-&-shoot product that is able to stand up to real world outdoor use.

Certainly, there is image degradation & it requires an extra processing step
to shoot 35 mm film & then digitally scan the image.  But, this is still
better than no pictures at all because the digital camera expired during the
trip or had to be so well protected that the photographer couldn't get to it
in real time to take the shot.  Thus, at least for me, a digital camera is
not really a viable option.

By the way, a 35 mm film negative contains about 20 mega pixels.  Thus, the
35 mm film image is not the image resolution limiting factor.  The scanner &
image processing software are always the resolution & image quality limiting
factors.  They still yield a scanned, digitized image that is adequate for
most purposes short of high magnification enlargements or glossy magazine
layouts.

The highest resolution digital camera I've seen so far is a 14 mega pixel
professional model from Kodak for about $5000.  That's pretty pricey for
most people & this camera is certainly not rugged or water resistant.
