The size of the fine JPEG is highly dependant (as it should be) of the amount of small detail present in the picture. Add the higher in camera sharpening which makes compression harder to achieve and you get a larger average size on the 300D than 10D but not by the amount you describe...Does anyone know?
Why is it that the size of a JPEG file (large) in an 300d (100 iso)
is around 3 Mb and a "similar" file in a 10 D is about 2 Mb?
Setting are both large/fine.

The 300D embeds a medium-fine JPEG inside the large JPEG for viewing on the LCD.

It also depends on the ISO setting. A picture at ISO 1600 will be noisy, creating more "detail" and a larger jpeg. Smooth colors compress better, so an ISO 100 picture of the same subject will be considerably smaller.

Are you sure? I thought the RAW file had the embedded medium/fine jpeg...The 300D embeds a medium-fine JPEG inside the large JPEG for

I don't think anything other than RAW as an embedded jpeg.

Well, to be exactly in an EOS 300 d the average is 3,1 Mb at large fine and with the 10 it 2,4 Mb.
see

but stil, why is that?

There is an embeded jpeg in all of the 300d files you can find a utility here
http://www.lincomatic.com/e3krstrip/e3krstrip.html
that will strip this jpeg and reduce your file sizes.
The process is lossless and has worked well for me, good luck.

that is really good to know. I will try this utility for sure. does it recompress the photo or simply extract the other jpg without loss?
