    opening your mouth as wide as it goes typically stabilizes the camera better than when its closed allowing for longer shutter speeds without causing as much blur

    To shoot with the lowest aperture available to your lens. Aperture referring to the size of the "hole" light is allowed to pass through in your lens, a low aperture meaning a larger hole and thus "Wide open", as wide open as your lens could possibly be.

    just to add

    people shoot wide open for several reasons:
    1) low light, larger aperture allows for more light in, thus, avoid having to shoot at a higher ISO
    2) more background blur to separate the focal point from the background

    There are some negatives to shooting wide open:
    1) the lens is not as sharp when it's wide open. It's generally much sharper when stopped down 1 or 2 stops (ie f/2.8 instead of 1.4)
    2) DOF is very limited, so it's easy to have your focus point off

    how do you know what your lens is at its sharpest speed?

    They're all a tiny bit different, but usually 1 or 2 stops does it. So you'd roll your wheel up 1-2 clicks. Sharpness usually starts at 2 stops and you get diminishing returns after F/8.

    gotcha, I'll play with that. Right now when I shoot I usually just shoot in a aperture that i feel suffice (its mainly me guessing and going with lighting conditions)

    f8 is referred to as the normal aperture and most lenses tend to be quite sharp, if not the sharpest at this setting.

    Not RLY. Rolling your command wheel til it clicks twice does not mean two stops. You went one stop if your camera works in 1/2 stop increments. Some even go at 1/3.
