Kodak DX6340 jpg size very small at max res.

Just a query for anyone with one of these 4MP cameras.
The image size at max resolution is below 1MB. This has me a little puzzled
as my 5MP Canon produces files typically over 2MB.

I am wondering if Kodak's jpg image compression is more severe than most.
Leading me into the question of to what detriment to picture quality.

Any feedback would be greatly appreciated.

Regards,
Tony

Tony,

I have the same camera and with the resolution set to maximum (which is
3.2MP, not 4) I have noticed that file size varies. Some pics are less than
1MB, but some are larger than 1MB. I haven't figured out why this is yet.
Quality seems the same. I have to
look into this. I wonder, would pics taken vertically be different than
horizontals in terms of file size?

I have the 4MP DX6490. Kodak uses "very clever" jpeg compression algorithm which
usually results in 500k file sizes. Occasionally I get 1.5MB files when there
isn't much sky or grass.

IMHO they overcompress sky, grass, and even skin tones if you're doing a
close-up portrait.

If you take a landscape with a lot of detail the compression is much less.

The amount of light and color increase the file size. When I take an astro
picture with my telescope the file size is very small. Example a moon
picture is under 200k and Saturn is about 50k.
