- Optical Filter Types. Polarizing filters: Enhanced color plus reflection control. Often described as the single most useful optical filter, a polarizer is a variable-control filter that lets you eliminate or minimize glare on many surfaces (e.g. water or glass, but not metal) by simply turning its front ring and observing the effect in the viewfinder.

- The optical density of the filter combined with certain logarithms determines exactly how much of each wavelength to block. This type of filter is useful in photography because they enable the user to capture an image accurately even in bright light. Neutral density filters can be either absorptive or reflective.

- A low-pass filter comprises several layers of optical quartz that have been cemented together and placed in front of a camera's sensor. They were put there to help prevent the appearance of moiré in images, or that odd effect when anything with a close pattern, for example ties or denim, would appear to be swirling and fuzzing, almost like the screen of an …
