Iím going this Friday to the sea for some long exposure images.
I have several Lee Neutral Density Filters 6 - 10 and 15 stop filters.
The 6 stop has no color cast problem, but in digital the 10 stop has a bleu cast. 15 stop not yet tried with digital or color.
Is it possible to correct this with film as with an digital image?
Probably going to use some Portra 160 or Ektar 100 on a 4x5.

Thx
Patrick
