It therefore gives a more natural, lighter feel to the photograph.Īlthough limited in application, it can be the perfect solution for many photographs. It lightens green foliage, which is particularly important with dark green leaves which can record very dark without a filter. ![]() When photographing foliage in black and white, a green filter is used almost exclusively. Due to the dramatic effects given by an orange filter it is recommended that shots are taken with +1 stop extra exposure. Most cameras with TTL metering will not be able to automatically correct for the filter factor. Most flowers will be recorded with a significant difference in tone from the surrounding foliage giving impact and effect.Ī typical orange filter has a filter factor of 4 (the manufacturer will supply the exact factor with the filter). An orange filter will also penetrate haze and fog. It is therefore an ideal choice to span the effects given by both these filters.īlue skies will be recorded in very dark tones on the print, giving bold contrast between the sky and clouds. Orange filters give stronger effects than yellow filters but are not as bold and dramatic as a red. Owing to the dramatic effects given by a red filter it is recommended that shots are taken giving +1 to +2 stops of extra exposure. A red filter will, in almost every case, give a significant difference in tone, making the photograph more interesting and dramatic.Ī typical red filter has a filter factor of 4 to 5 (the manufacturer will supply the exact factor with the filter). When shooting flowers without a filter there's often little tonal difference between the flowers and the foliage in the print. ![]() When used with a film like it can create an infrared style look. A red filter will also give marked penetration of haze and fog. Pictures of mixed material buildings gain drama and clarity. Blue skies are now recorded as black on the print, resulting in an impending thunderstorm effect. Unlike the subtler changes given by yellow and orange filters, a red filter can create bold and dramatic effects. Most cameras with TTL metering will correct automatically for the filter factor but check your particular model. This gives more differentiation between the different colours of foliage while flesh tones have a more natural look.Ī typical yellow filter will have a filter factor of 2 (the manufacturer will supply the exact factor). A yellow filter will also give improved penetration of haze and fog.Īlthough a yellow filter darkens blues, it reproduces green, yellow, orange and red in lighter shades. This works by darkening the blue sky, giving a greater visual separation between the darkened sky and the white clouds on the final print. ![]() Many photographers use a yellow filter to “bring out the clouds”. It gives an excellent balance between photographic effect and ease of use making it a useful and versatile accessory. Yellow FilterĪ yellow filter has always been the “classic” first choice filter for black & white film photographers. Colour filters therefore allow us to modify, at the point of capture, the way the film will respond to the different colours.Įach coloured filter produces a different effect on the scene. Normal black & white films are sensitive to all wavelengths of visible light although how they interpret the colours of that scene will not always match the way you see it. In black & white photography, colour filters in particular are useful as they can control how the colours in a scene are reproduced as greys. However there has always been a benefit to getting it right in camera. In both analogue and digital photography it is possible to recreate some of these in the darkroom or digital darkroom. Filters have long been a popular accessory for photographers and offer a number of different functions or effects.
