Hi from Paris,
I bought a Sony-DSC-F717 a couple of years back - went into my list
of "Best-Spent Money" items - gives beautiful photos of 5 Megapixels
(I never change the setting).
The photos each represent about 2 MB, and with that, I can print out
a high quality photo on A4, reasonable quality on A3. My close-up
photos of flowers would make many photographers green with envy.
What I mean is that a 5 megapixel/2 MB photo is enough for me, and I
am a stickler for quality. I have many Rev stacks that display
hundreds of jpg photos, and so I had to scale down my photos for
rapid display and reduced disk space.
I use GraphicConvertor (Mac) - also on my "Best-Spent Money" list.
You can batch scale-down a complete folder, to the size of photos
you want.
Just in case I ever want higher quality (and I have more than 30
years of 35mm negatives to examine), I also have a Nikon DiMage 35mm
scanner, and I CAN scan the negatives up to 100Mb files (what for, I
will never know !)
I scan my BEST colour negatives to about 20 MB, and I CAN print them
up to 1.5 metres x 1 metre posters - much more than the average Yogi
Bear requirements.
The latest cameras are providing more than 15 Megapxels, and
technology will take us much higher within a very short time ! I'm
not sure what that represents in MB, but it certainly is a lot. I'm
also unsure of the need for cameras of this quality for the average
user.
Unless you are a professional, you don't need photos of this
quality, so why take them ?
If the optics are up to the task, the the Hi Res eliminates any need
for zooming; you do the editing on the computer.

remembers these high grain, 400 ASA Ilford films...
