Light Scale in EV

This chart may help if you can understand how to read it; (The green and red values show 2 example calculations).

Start with an EV, then slide to the right and pick an fStop, then slide up and pick a shutter speed and finally, slide to the left and and you see the needed ISO, also you could go in reverse to find what EV you are shooting in.

Thank, comes in very handy.

What is to be considdered as dark or low light situation?
IMO, below EV 3-4 is "low", below that "dark". Rationale being that for something like the k-x / K-5 EV 3-4 is where one can still get decent quality handheld snaps but going below that would need tripod / flash (or >= ISO 6400 ).

Crap! I've had it wrong! I always use the f1/1sec/ISO100 rule to do figuring in my head if I need to, but I thought that represented EV1. I've been 1EV off all this time.
