Great quality filter and no color shift!
GENERAL IMPRESSION
This is a filter similar to the very well known "Black Pro Mist" filters used in movies. There's a number of reasons to use this type of filter like:
– smoothing up the whole image while still retaining important details
– making the transition from highlights and blown out areas to the surrounding areas smoother (it basically creates a "glow" around the brighter areas).
– when you have people on the screen, it helps masking out skin imperfections and giving that classic vintage Hollywood look.
At this 1/4 intensity it really brings in this smooth vintage look, but if one decides to go up to the full diffusion option it can add a very dreamy effect. That's a decision to take carefully as this type of effect cannot be undone on post, it's baked to the image. On the other hand, this type of effect cannot be done with the same quality on post. It's really a decision to be made at the film set (preferably discussed BEFORE the film set between Director and DP).
QUALITY
The built quality is very good. The filter itself is made of good quality glass and it is fixed to a metallic threaded frame. It comes also with a very sturdy metallic protective cap, also threaded. Bear in mind that because the cap is threaded, there's no "quick release", so it takes some time to attach it and detach it from the filter, which can be not very practical in some situations when work speed is a factor.
Filter and cap fit perfectly in a convenient protective hard case.
In term of optics, I took time to take some measurements with a light meter and a color meter and as a result I discovered that at this 1/4 intensity, this black diffusion filter eats up 1/3 of a stop (your image gets slightly darker). On the color side, it performs very well as a didn't notice any color shift caused by the filter.
CONCLUSION
This is a very good filter! The fact that it does not cause any changes in color and eats about 1/3 of a stop of light only, makes it consistent with another filter I have from other manufacturer, but different diameter. That means I can use both in the same job without worrying about overloading post production with avoidable corrections and adjustments from take to take when using different lenses.
