Thread: ND and grad ND

  1. #1

    Default ND and grad ND

    hello guys.
    pardon me if i'm asking a dumb question.
    google-d it. done reading.
    not done with understanding between these two.
    doesn't it have the same effect?
    to reduce light and increase contrast?

    one is graduated, one is not.

    gnd filter

    to even out exposure between background and foreground when there is a difference.

    nd filter is to extend exposure. none of them increase contrast, but there is reduction of light - whole frame for nd filter, part of frame for gnd filter. rather - a gnd filter "reduces" contrast. your sky will not be as bright as before, therefore allowing your camera to be better about to capture the scene by "compressing" the dynamic range (distance btw brightest and darkest point).

    sharpness and contrast has nothing to do with nd filters. or gnd actually.

    proper exposure will be related to gnd at least.. are you sure you have been reading about gnd properly? go and check out singh ray's website.

    I got a little unfinished writeup on GND here.
