    B+W Filters colour cast

    I have 3 B+w filters they are 3stop, 6stop and 10stop, the problem I have is the reddish colour cast you get. My question is there an easy way to get rid of it in PS5? and yes I do shot in raw.

    I suspect that it can be fixed with the white balance adjustments in Adobe Camera Raw. At least that is what I do with my Lee Big Stopper.

    I use C1 PRO and select the white balance from a point in the image. I can only assume that you can do the same with PS5, but I don't know for sure.

    if there is a 'reddish tint' then the opposing colour channel is the green.
    So in the tint section of the WB adjustment tool, you add more green channel.

    When you get a reddish cast in using grad filters, using this WB/tint method is hard to next to impossible to correct for, so you need to use a graduated selection over the affected area and lower the red channel/increase the green.
