ND Filters adding tint?
Gentlemen,
I have a demo EX 1 and have set it up by eye, 3200k, matching to the subject to the monitor after setting bars on the CRT.
Took the camera outside with the same knee point, gamma, etc.
White balanced to 6300.
Used a polarizer and at times since the sun was blocked out, took off the cameras ND filter for proper exposure.The clouds had a pink hue to them. Even the grass seemed a little red. I thought it looked redder when the ND filters were on.
I was using the High Sat setting on the Color matrix since the client wants that look so the product pops.
Could this be due to the white balance?
Knee point?
Slope?
Which setting(s) is/are messing me up?Matrix settings (on):
*High Sat
Level : +60
All other settings : 0*Knee (On)
Auto : Off
Point : 80
Slope : +26
Sat level : 0*Gamma
Level : +25
Select: Stnd 1*Black : 0
*Black Gamma : 0
*Low Key Sat : 0
These looked good on an HD Sony studio monitor (CRT).
Looked a bit red on the editors LCD and my home LCD. (Yes I know that LCDs can have a red tint to them).
The clouds were just too pink for my taste. Where did my whites go?Any level-setting suggestions would be welcome.
When are those EX 3’s gonna get here?
Thanks,
Paul

hi,
could be the fact that the ND filters aren’t neutral. In Digibeta cameras for example it is possible to set an offset for the ND’s if they aren’t neutral.
Another possible thing is the paper you did your white on. some chloride bleached paper fool the white balance. Possible solution: white card from porta brace.
but first try out white’s with differnt nd’s and then remove the nd’s.
I don’t own the ex1 – just guesses.
Best regards

Armin,
Thanks for the input.Looks like my home monitor is really set up warm-thought I had it dialed-in beter.
Footage looks OK at the post house.I am still wondering if anyone has any suggestions for getting that knee to work better in clouds when the f-stop is set for a wooden swing-set.

Many polarizers add tint and changes as you rotate them. Shoot a white cad and rotate the polarizer and see if that is what’s causing your problem.
