Don't know about nikon...but with RED, while technically you have a tint control on the camera, it's really just metadata, meaning the actual correction is being handled in post. As for the benefits of pre filtering the image as you've suggested, I'm not sure there is any benefit to "cutting wavelengths" (filters don't shift colors, they remove them) prior to exposure compared to adjusting the gain on a particular channel in post. One may give you slightly more noise, while the other will give you less saturation. If you're shooting H264, this may be the way to go, but with ProRes or Raw, I'd probably just make the correction in post, as the 10bit 12bit workflows are more that adequate for this type of small correction.
Additionally....I find that there's a certain amount of inconsistency to the amount of red I see in my images. Not sure how much is related to the ND filters I use (firecrest --which seem to cancel out a little red), or the ambient temperature. I'd love to see your results with your home-made filters...but I'm a little concerned about stacking a gel with a ND in terms of sharpness and flare, and of course, those old wrattens were meant to be handled with kid gloves...:-) |
