Modified of course if you know me I found something great, and still had to modify it.
This is, for all intensive purposes, a no photosensor light meter. I guess an exposure slide chart is better way to call it. I found it at: expomat.tripod.com/
Handy little chart that allows me to see what my proper exposure should be for my meterless cameras. I modified it just a little, but to show what the markings should be for 10 Stop ND filters. I also added 1 sec indicators for 9 stop and 3 stop.
Of course I didn't stop there… this papercraft has a window, so I added a plastic window just to make it a little more rigid and durable.
I sent my redone chart to the original creator. I don't know if he'll republish it, but if anyone wants a copy of this handy chart, please feel free to message me and I'll send you the link to my modified version.
