“Neutral density (ND) filters are supposed to be devoid of color shift. Ideally they only affect the amount of light entering the lens, not the color balance. Unfortunately, it is very difficult to produce an ND filter that is truly neutral. This is why I set out to test four sets of filters. I wanted to see how neutral they really are. For this test I used ND filters from Schneider, Formatt, TruND, and the internal ND filters of the Canon C100. The results may surprise you, just like they did for me. Continue reading to see how these filters stack up, as well as to get access to the downloadable frames.
Before we dig into the results, you may be wondering why in the world I would even bother testing ND filters. That is simple: consistency. The more consistent and the more neutral the ND filters are, the more accurate the colors will be in addition to saving time and money on set and in post.
Imagine for a moment you are shooting an exterior scene on a partially cloudy day, where the light levels are constantly fluctuating 1-3 stops as the sun goes in and out of the clouds.”
