Special Effects Filters
The final category of filters is the special effects filters - filters that have a specific purpose when shooting. [an error occurred while processing this directive] The first that I like to use is the Circular Polarizer. A polarizing filter ensures that light reaching the camera does so in a straight line. This has the effect of reducing glare on windows, water, glass, and other shiny surfaces. This is very handy when you are shooting a subject in a car. By reducing the glare, the window magically becomes transparent.
Polarizing filters also have the ability to bring out deep saturated colors although the effect can change from one area of the image to another.
Another special effects filter you may want to add to your collection is the diffuser. The diffuser scatters light as it enters the lens, thus softening the image. This is great as it can remove blemishes and wrinkles from your subject, causing them to look much younger.
The diffuser also has the effect of causing the whites of the image to bloom or glow. The softening and added glow can make the image more film like.

To go along with the diffuser is the Black Net filter. Instead of enhancing the whites and softening the image, the Black Net filter causes the blacks of the image to get darker. It is called a Black Net because it is similar to the black nylon pantyhose stretched across a lens. Again, this is especially useful if you are trying to get your video to look more like film.
Don’t be afraid to combine filters. Filter holders and screw on mounts allow you to stack several filters together. Combine a diffuser, black net, and ND filter and you can create a very realistic film look on video.
