Actual zone system

[Peter De Smidt]

its going to be a while before i can take a camera outside.... i havent taken one outside in under 30* before and wasnt to happy with how they behaved. 10* and a windchill beloe 0* aint going to be good, for nothing.

Well, sure. I just got back from the mid day dog walk, and it was -1F actual temp. But...if you're just running some tests, you can photograph out of a window.....
