I am taking advantage of the fact that I live in the near far North and will not be seeing the sun for a few hours yet. I set my trusty Minolta Auto Meter IVF to ISO 400 (reflective with dome off) and went looking for a dark hole to crawl into. The big problem was finding a place I could meter and see the display as well. Finally I found a tone that gave me 1 second at f1.0 and 0/10ths (the meter reads to tenths of a stop). I then held up an old B+W 39E 010 1x filter (UV not MC)in front of the measuring cell and hit the button. SAME READING EXACTLY.
