Shoot raw and adjust the WB later. No big deal.
thanks KY1977
use your matter
able to solve the problem with adjusting white balance
lucky i shoot it with raw
manage to save the image
i regretted it and invested a few filters... thinking switching to High-Tec, close to Lee's at cheaper price...
From what I read, Hi-tec also exhibit some color casting, although not as bad as cokin.
Actually, Hitech, Lee and Singh-Ray all have some color cast when NDs are stacked or very high (except for Lee's Bigstopper). Cokin has bad rep 'cos even their low NDs transmit IR.
