But it's sometimes nice to know what aperture and shutter speed you shot at. Sometimes we remember, sometimes we don't. Helps with the learning process. It just means that we learn more quickly that at f/0.5, the Nocktislurp is only sharp in the center, but at f/1.1, it's sharp as a tack corner-to-corner. As in, "Darn, my picture sucked because I should have slowed the shutter a notch instead of opening up. Jerry: Actually, the M8 *is* calculating the aperture. The little blue dot near the M8 logo is a second light meter cell, whose primary purpose is flash exposure calculation. Using this cell, the camera compares the off-the shutter light measurement (which is behind the lens and aperture) with the blue dot (which is out in the open). It can calculate the approximate aperture based on the comparison. Problem is, it's only accurate +/- one stop, so Leica doesn't put it in the regular EXIF data. There's been a bit of speculation on the Leica-Camera-User digital forum that the value might be stored somewhere in the manufacturer's proprietary section of the EXIF. If it is, I'm sure somebody will figure out a way to access it in some EXIF viewer. If I recall correctly, Sean Reid explains this on his site. --Peter At 11:37 AM 5/6/2007 -0700, Ted Grant wrote: >Please explain, as usual in the simplest of terms, because this EXIF isn't >recorded does it mean the picture is lousy?
