Do u use a grey card? Is there a certain brand to buy?
When shooting, do u use the live view?
MF or AF?
I was playing with my camera and the camera manual yesterday and realized using live view lets ya zoom in and see if u have focus down before shooting. I felt semi smart after that haha. I have read the manual before but find when I reread it, I always learn more, like the info was put in after I read it the first time LOL.
