This video from B&H surveys various optical filter options for video production. Mia McCormick discusses the basics of neutral density filters, circular polarizing filters, UV filters and soft effect filters. You’ll learn about the unique benefits of using an optical filter during the capture process—benefits which cannot be replicated in post production.
Once a new camera is chosen, purchased and received, the depreciation clock starts immediately. Regular light maintenance is important in order to keep a camera in optimal working condition and ready for any situation.
Not long ago, filters were part and parcel of any worthwhile camera system. If you wanted to warm up the palette of a dreary day, you used a filter. Ditto for converting daylight to tungsten light, tungsten to daylight, and daylight to (or from) fluorescent lights.
With the exception of the filters used for black-and-white photography (see the article Black & White Landscape Photography) the numbers of filters used for capturing color landscapes are few, mostly due to the fact that, in digital imaging, many white balance and filter effects can be addressed in camera.
While many "looks" can be achieved in post-production, certain aspects of the image are better controlled before the image is recorded. Optical filters modify the light before it enters the lens. The benefit of using optical filters instead of digital filters is that there is no added time in post production and less degradation of the image quality, especially in HDSLRs, which already have limited color space and a highly compressed image.
There is an old saying amongst some photographers that using a UV filter will degrade the quality of your image. But is it really true? We put that to the test recently in the B&H Executive Offices. We'd like to know, in the comments below, if you can tell the difference between the two images, and tell us which one was shot with a filter and which one wasn't.
