Russ, If you've configured the e-10 to output jpg formatted files, file size has NO real relationship to the resolution, the e-10 manual says at the SHQ setting each jpg file will be 2.8 MB. The compression algorithms used for data streams look for patterns of the same colored pixels. So for example if the program sees in the "raw" TIFF file that the next 400 pixels are the color "red" then it puts into the jpg file the encoding for 400 pixels of red, and then looks at the next pixels. If you set the e-10 options to output TIFF files instead of jpg, these files will be 11.4MB each, no matter what the repeated pixel content is. I use the e10 at it's highest resolution for jpg files, this is 2240w X 1680h at 144 pixels per inch, this comes out to 15.556''w X 11.667''h, total file size for this picture is 2.41MB... Hope this helps, Rick P.S.
