It is only possible when clients give creative freedom to the videographers. haha.
The color cast for the Haida is more towards green. It's more manageable since Sony (the camera i used) tilts towards red. The green helps to bring the skin tone to a more natural looking as compared to other ND filters i used. Again, I haven't been using many other brands of ND filters on videos to give a good take on it. On the overall, I am happy with the ND filters I got.
Thanks for the recommendation.
