Yellow color shift on EX3

Vincent Oliver · November 23rd, 2011, 12:57 AM

Yes, the Vortex cards come complete with white and grey reference cards as well as 4 grades of warm (light blue), 2 grades of cool (yellow) and a green card - (for adding magenta). I would have liked a magenta card too for removing a green cast when shooting on a green field (sports events etc.)

Each two sided card is sealed in a protective plastic sleeve and should last for many years. I have been using the small set of cards for a couple of years and generally get great looking shots. However, you have to be careful when selecting which grade of cool card you use, otherwise you can end up with a shot that is too yellow. Experience and shooting test footage will be your best option in this case.

Thank you Jerry and Vincent for your recommendation of WarmCards.
I wasn't going to post anything, and I don't mean to derail this thread, but I just need to comment on something that Vincent said.

A magenta card would not remove green, it would remove magenta, thus making your problem worse. Our "Minus Green" card that already comes with the kit is the one you'd want to use in situations where there is an over abundance of green and the camera's normal white balancing is not compensating for it.

Just testing you Doug, you are quite right a Magenta card would increase the green. I'm working too hard and not thinking enough.
