If you own a Pentax Digital Spotmeter, you might be interested in my free, updated version of a Zone Ruler for it. This is my favorite lightmeter for the Zone System but not without the Zone Ruler. This customized ruler is a visual reference and will simplify zone placement. Zone III and VII are marked to place shadow and highlight details. I suggest you print this scale onto a self-adhesive label, cover it with clear tape before cutting it to size, and then affix it to the Pentax Digital Spotmeter by centering it just below the EV scale. You find the scale in my 'Library' section of my web page under PDZD. Comments always welcome at info@xxxxxxxxxxxxxxxx Regards Ralph W.
