So far, I've been storing my pics

On my monitor, I really can't see any difference
between these pics, and higher resolution/file-size shots.

I've started to "album" my files on a CD-rom.
At last, slide shows thru the TV using my DVD player.
once again, I can't see any noticeable difference
between the 200K files, and the mega-sized files.

First premis;
Why bother with the mega-size photo files ?
Unless you're selling your pics to National Geographic,
or making poster-sized enlargements ??
Is this a case of "mine's bigger than yours is" ?

No reason. If you are satisfied with the quality, I see no reason to
try to make you dissatisfied. I have a 4mp Kodak, and the file sizes
are about the same as yours, which is just a bit TOO much compression.
I wish Kodak had given me an option for larger files, with less
compression, although this only matters on 10% or less of my photos, it
DOES matter sometimes. The larger the file, the more information that
is stored. JPEG compression discards picture information. Usually, you
can't notice, but on some subjects, it becomes noticeable.

Hi RJ,

Sounds like you are really enjoying your new camera. Digital is great is it
not?

The reason you do not see much a difference in the two formats is due to
their being online or screen formats. The real difference will be later
when you want to print your images. The larger the file (more information)
the better the print can be. So, if you send a file for printing send a
larger file. It will make a difference. Also, this is key in the capture
of the image, i.e. capturing larger file sizes. If you are only going to
use the images for selling things on eBay for example, then you do not need
large files. If you are going to print however, use the best setting on
your camera.

Talk to you soon, RJ,

Happy Holidays
Ron Baird

Ron Hunter:
Really? 100-200 KB per file from a 4 Mpixel camera? Wow, that's tough -
those files won't tolerate a lot of editing or cropping, I'll bet.

I had an old 2 Mpixel HP and it's (best resolution) files were 600-800
KB. And even then, they were only good for a bit of red-eye reduction
or color adjustment, they didn't do well with cropping or enlarging at
all - JPEG blocks, moire and jaggies everywhere. Even without cropping,
the skys often had color banding from JPEG compression.

As to the OP's questions, I think he'll have to learn for himself....
If he's happy with what he's got, more power.
