White Balance with Filter/s

[russellsnr]

Hi, As no question is a stupid question if you don't the answer.
If you use an Expodisc or grey card etc etc to set a WB in camera will adding a filter after you have taken your reading affect the outcome. Really thinking along the lines of using ND grads & Polorizers.
Thanks you
Russ.

It shouldn't but it might! Older Cokin grey filters were notorious for giving a magenta cast (although the newer ones are supposed to be better). Worth taking a few test shots and seeing what the results look like then altering your technique to reduce/remove any casts.
