I posted this over on largeformatphotography.info as well but am going to post it here, too -- I couldn't find one of these so I made my own in illustrator because I sure wasn't paying $6 shipping for the $8 one on ebay. I'm sure the person who makes them is perfectly lovely but $14 for a sticker that can be sent with a stamp chafed me. These exist for the digital spotmeter but for some reason the V must be old enough now that the old links are all dead. It's already scaled correctly. Print this out at 100%, stick some nice packing tape on the top, cut it out. I held it with a pair of needle nose pliers and sprayed 3m super 77 on the back and then affixed it to the spotmeter dial. Make sure you have a number centered on the arrow at the bottom so you can position it correctly. Super 77 will let you slide it around for a bit before it cures so you can get it just right. No warranty expressed or implied, may your development always be N.
