This talk explains the technical and creative aspects of the use of filters in outdoor photography. I'll tell you how to manage exposure and understand natural light control with the use of filters and the kind of subjects you’ll need to use them with.

I explain the range of filter systems available and how they work. Finally, you’ll see recommendations on what to buy (and what not to buy!).
This talk is an important follow on from the talk on Long Exposure Technique as the use of filters is fundamental to this style of photography
