Why You Should Be Using ND Filters For Interior Work

Last week I talked about the importance of in camera filtration, and this week I am going to address why you should be using ND for interior work. Typically, ND filters are thought of as exposure tools that are only used for scenes that take place outside. While they may have started out as a tool that was primarily used for exteriors, that is no longer the case. As camera technology continues to advance, the ND filter is playing a bigger role when shooting indoors.

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."
