I've got a headache trying to understand aperture of the camera. I understand that the lowest aperture gives you a blur in the background of the object (greater DOF).
So do we only use the lowest aperture when we are taking still shots and not to focus on the background?
How about when we are taking picture of a night scenery? Do we take in high aperture?
I know these question sounds silly, but I need to understand this in order to learn more about my camera. Thanks guys.
