Black and White Filters

bwTo use filters for black and white photography, you need to think differently. A filter will lighten any colour that is similar to its own, and darken other colours. A red filter, for instance, will make a red post box show as almost white, and a blue sky as almost black, as the relevant colours are either transmitted or absorbed. Green filters are popular for lightening foliage or grass, and blue filters are often used to enhance skin tones and texture for portraiture, as they will darken pinks and reds.
