Low key
A low key portrait is the exact opposite of a high key picture ( see pp . 62-3 ) . The prevailing tones are all dark , the shadows are heavy , and large areas of the picture are underlit . The style is traditionally used for male studies - it gives an impression of strength , resilience and physical force . But a low key treatment should not be reserved solely for male portraiture , since it is equally effective in the interpretive treatment of some women . For example , I used low key lighting for a portrait of the actress Glenda Jackson ( see p . 74 ) to bring out the strength of her personality .
The best low key light sources for portraiture are strong , contrasty , highly concentrated spotlights . In low key studies it is important to limit the illuminated area , and this is not easy with floodlights which provide a broad beam of light . The most effective low key studies are often created with no more than one light source- a spot directed onto the face , or even
part of the face , with only a suggestion of the rest of the head and shoulders . However , at times it may be preferable to open up shadow areas a little - you can place a reflector near the camera and control the amount of shadow detail by altering the distance of the reflector from the sitter . The human eye is not reliable in deciding the required amount of shadow details what the eye sees the film is often blind to . Because of this you may sometimes have to provide stronger fill - in than seems necessary . For a precise result , take a meter reading on both highlight and shadow areas . Where the difference is more than four stops the shadow details will not record . For example , if the exposure for the face is f16 , the shadow area should register as not less than f5.6 . A difference of two stops is preferable ( this would give an exposure of f8 for our example ) .
Capturing mood For this shot , I used a low angle and cropped in closely to add impact and give the illusion of high musical notes . The low key treatment seems to suit the mood of the jazz music . Mamiyaflex C3 , 80 mm . 1/60 sec at f16 , FP4 .
Lighting for low key ▷ I used straightforward low key lighting for this shot , see diagram below . The beam from the spotlight directed onto the face catches the outline of the glass . Fill - in is from a reflector near the camera and I placed an additional light above the head to reveal its outline . Pentax 6x7 , 105 mm , 1/30 sec at f16 , Tri - X .
