How does WarmCards compare to glass warming filters?
Using dedicated “warming” filters is popular these days, but very problematic. First of all, you have to remove the filter every time the lighting conditions change and you want to re-white balance — otherwise the camera will compensate for the warmth created by the filter and the result will be a neutral white balance with no warming. Taking the filter on and off repeatedly is a hassle. Second, unless you have a matte box, most lenses are only able to handle one screw-in filter at a time. What if you also want to use a SoftFX, ProMist, polarizer, or other filter at the same time? Yes, you can get “warm” versions of these filters but they only come in one grade, and each one of them will cost more than the entire WarmCards System. Third, what about matching footage with other crews? Even if two crews have the same warming filter, the white balance will still be affected by what you white balance on.
