WebOD Total of 2.3 could be created by stacking OD 0.3 + OD 2.0 or OD 1.0 + OD 1.3.. Types of Neutral Density Filters. There are two types of ND filters: reflective and absorptive.Reflective ND filters consist of thin film optical coatings, typically metallic, that have been applied to a glass substrate.The coating can be optimized for specific wavelength ranges such as UV … WebThis is where something like a variable Neutral density filter helps by reducing the amount of light that passes through the lens. That means that we can have the lens wide open, get that shallow depth of field and still get a great exposure. Here are some of my favorite Variable ND filters and remember to get one that fits the diameter of your ...

One thing to be aware of though, is that circular polarizer lens filters don’t work well with variable ND filters (like this one). Variable NDs stack two polarizers together and can have weird effects when combined with an additional polarizing filter. WebOct 12, 2024 · How do variable ND filters work?
