    My friend and I are having a friendly debate about aperture.

    He insists that f/22 is larger than f/2.8 and I disagree, because it's measured as 1/22 and 1/2.8.

    1/2.8 is a larger number than 1/22 isn't it?

    2.8 is a larger opening than a 22.
    Smaller the opening the larger the aperture

    f/22 is a larger number than f/2.8. F/2.8 is a larger hole than f/22.

    f/2.8 is a larger number 1/2.8 or a little over a half versus f/22 which is considerable LESS than a half...

    f/2.8 is larger aperture opening than f/22.

    f/22 is a larger (deeper) depth of field than f/2.8.

    Next question pertaing to open aperture = great landscape and portraits.
    Correct

    How does shutter speed now play into this.

    I beleive a fast shutter speed is for action, and a slow one for night shots, landscapes and portraits
