Lesson 9 : Types of Filters

Introduction

Camera filters are transparent or translucent optical elements that alter the properties of light entering the camera lens for the purpose of improving the image being recorded. Filters can affect contrast, sharpness, highlight flare, color, and light intensity, either individually, or in various combinations. They can also create a variety of "special effects." It is important to recognize that, even though there are many possibly confusing variations and applications, all filters behave a reasonably predictable way when their properties are understood and experienced. Most of these properties related similarly to filter use in both film and video imaging.

In this modern age, people think of filters only as options on Adobe Photoshop. Many forget that filters were and still are glass rings that are screwed on to the front of your lens, to provide the special effects. It is true however that Photoshop can mimic the same on computer, so many photographers choose NOT to use the glass filters, and later edit the photographs on computer. It is good though, to have an idea of what filters really are, even if you are a great Photoshop user.
