I have LOADS of questions actually, lol. Im new to doing this kind of photography and sort of got thrown into it on a whim from our company. When I was shooting at the board of elections last night, I tried using the card to determine WB but everytime I set it and took another picture everything had gross green haze to it.
As far as 'metering points' go, is that the spot I choose to focus when I press the shutter down half way? And from what your saying I shouldnt be using the card to determine WB anyway? (Sorry for being a noob

) Im learning all of this stuff sort of little by little but I need to learn as much as I can because im getting more and more demanding assignments that require me to have some sort of picture taking skills.
