NOTES FROM BOOK:
Prakel, D (2007) LIGHTING. New York. AVA Publishing SA.
I made these notes to support my understanding whilst working through the exercises in The Language of Light and in preparation for shooting assignment 4.
“A photographer must be prepared to catch and hold on to those elements which give distinction to the subject or lend it atmosphere. They are often momentary, chance-sent thing…sometimes they are a matter of luck… Sometimes they are a matter of patience” Bill Brandt cited in Prakel (p57).
Daylight “is a combination of direct light from the sun, from the sky, and light reflected by the clouds” (p58).
Colour temperature is bluer when the light falling in shadows of an image are illuminated by skylight alone.
Morning light: Soft and diffuse. Before sunlight red to violet blue, immediately before pinker, at daybreak yellow.
Noon light: Though harsh does give saturated colours. Winter noon light is higher and has a warmer colour balance than photographic daylight.
Evening light: Strong, low angled light casting long shadows leading to crisper images. Sunsets are rich red and gold,
Night light: Gives an inky black or softly coloured backdrop.
Seasons: The winter is a lower colour temperature and the summer higher.
Location: Mountain top direct light is unforgiving and bluer. Coasts are giant reflectors as is sea spray. City light and tall buildings block all but overhead light. Vertical surfaces reflecting light. Pollution shows in a telephoto lens as yellowing or browning.
Fluorescent light: Is not a continuous spectrum of colours but a combination of green and orange and magenta light.
Street lighting: Is usually mercury or sodium vapour – giving violet/blue and yellow light respectively.
Neon light: Comprised of gases in a tube used to create colours.
Colour filters and film: Daylight and electronic flash (5500K) Tungsten (3200K)
Exposure: when contrasty lighting increase by 2 stops.
