    Default ques about cokin filters

    i managed to dig out some old cokin ND filters.

    it was written ND 8x and ND 4x.

    how many stops of light does the above 2 cuts?

    Remember it as follow:

    ND nx
    n = 2^f
    ...where f = number of stops of reduction

    e.g. ND 64x

    64 = 2^6
    .... therefore 6 stops reduction
