I'm wondering, is there a "best" aperture for printing from a 2 1/4 neg. on an 8x10 sheet? It seems like my exposure time is very short, ( 2 to 3 sec.) probably because the final size is so small, but I seem to remember something about 16 or 32 being less sharp? My enlarger is a condenser, and my lens is a nikkor 80mm 5.6. Thanks for any advise. Russell.
