The settings are actually in every picture file. If you use Windows 7, and probably Vista, save it to desktop, right click, click properties, click details tab. It lists everything about the photo; aperture, shutter speed, ISO, focal length, etc. So, for the picture of the red flower, you probably don't need to use ISO-400. You can turn it down to 100 and be good. Although I guess you used an automatic mode for these?
