B+W Circular Polarising filters are an essential for all camera bags. Polarising filters provide some of the most impressive effects – and ones which are virtually impossible to recreate with digital manipulation software.
Polarising filters provide control over how much reflection you choose to include in your image.
By rotating the filter in its amount, you can control exactly how your image will look. One of the most useful features of polarising filters is that it can increase saturation – for example on blue skies, or foliage – and also reduce reflections on non metallic surfaces including water and glass.
