What does a polariser filter do?
Using a polarising filter is essential to remove the bright light on wet and metalic or reflective surfaces.
Not only does it improve exposure, by reducing the brightest areas - thus bringing the dynamic range closer to what the camera can record, but it increases contrast and saturation.
To find out more on what filters can do and how to use a polariser properly attend one of my photography courses or location workshops to understand how to use it properly without creating artificial effects in a photograph.
I was recently asked to judge an on-line photographic competition - Blocking Tactics - and was surprised by how many of the 350+ entrants had not used the polariser to do the job it was designed to in a way that was creative or balanced.
