hi, I was reffering to a high quality reference file, similar
to a RAW but already optimized and saved in a low compression jpeg
format, not a file
just suitable for 4x6 prints.

The irony of this is that for prints, especially small ones like the 
4x6's that are the most popular for general use, the Pentax JPEG output 
is actually better than a more heavily sharpened print.

Most minilabs oversharpen everything they print.
