    Filters and a Magenta Caste


    Been playing with filters

    I am getting a Magenta (reddish) caste when I stack a 1.2 attenuator on a 1.2 ND Grad. Both Schneider 4 X 5.6.

    This is on a Canon 5DIII with 24 L and also a 24 - 105 L . On the 24 - 105 I have tested it at 24 - 55 - and 105. All have a color caste.

    I haven't tried my IQ 180.

    Anyway to avoid this other than not stacking? Individually not a big problem. Would a IR cut filter help? If so which would be the best one? Putting a bunch of glass in front of the lens is not my idea of a good time.

    Thanks so much
