It's a topic photographers start to tackle as they continue to develop their skills, continue to tackle new subject matter, and continue to tackle the processes in order to capture better photographs. Of course, all of these photographic avenues we try to improve ultimately trickle down to the same solution, much like the branches of a tree to the trunk, and that is - the betterment of capturing light. Each photograph - a simple exposure to light. There are literally an infinite number of situations in which a camera can be asked to best capture that pesky stuff we call "light." Some of these situations can best be captured by simply fully understanding how to use a camera and how to spin the dials, some may call for the use of a reflector, diffuser, or even an addition of a light source, and some require the introduction of a filter to best capture the moment. In this article, we'll be taking a look at the latter, an in-depth look at the various filters available to photographers, which ones to avoid, correct and incorrect uses, and when to best use them. The importance of using filters in your work will largely depend on the type of photography you capture. They can have a very dramatic or very little effect on your image, depending on your knowledge of how and when to use them.
