The shutter speed and aperature setting has no almost no effect on compressed file size.
Subjet matter does.
The discussion is mainly concerned about the image quality of the S2, not the actual size of the compressed images. Previously it was noted that the S2 seems to create smaller jpeg's for the same image when compared with the C-755 - I guess the point of that post was to ask if this was an indication that the S2 was producing lower quality images.

My own previous point was to propose/ask to what degree exposure time might contribute to the amount of noise/quality of an image (regardless of aperture or zoom).

Note there is a lot of info about the S2 available via the "S2 blog"


For example, the document at the end of the http://www.digicamhelp.com/canon-s2-...on-s2-tips.htm link
discusses the softness issue:
Generally image quality was good, though not perfect. The images are generally well exposed, well focused and pretty detailed. If viewed at 100% they have the same smoothness - and overall lack of biting sharpness - as the S1 IS results, though they are considerably better. We also found sharpness drops fairly dramatically at apertures of F6.3 and higher (due to diffraction effects), though this is by no means unique to this camera - it's just useful to know you get the sharpest results in the F4.5 to F5.6 range.
