IR ND Filtration + EPIC


[HIGHLY RECOMMEND WATCHING IN FULL SCREEN]

As cameras get more and more sensitive to light, infrared (IR) pollution becomes a bigger issue as stronger neutral density filters are used to maintain exposure. IR pollution ends up changing the color rendition of the entire image and can result in some VERY funky color shifts. (I have seen dark green leaves change to magenta for example.)  These color shifts can be next to impossible to get rid of once they are recorded into the digital image. There are creative ways to get rid of this in post, but many of these solutions - like rotoscoping and painting out the problem - are cost prohibitive. Besides, a "problem" like this should have been corrected in the camera at the time of filming, not left to post. Always remember this mantra, and practices it daily: "Fix it in camera, NOT in post."
