There are various ways to read light levels.
Reflected Meter Reading |
Incident Meter Reading Note the White Invercone is in place |
INCIDENT READING - (left)
This uses the light meter with the invercone in place, and measures the light falling onto your subject. This works best for high contrast subjects and when using colour transparency film as you need a very accurate reading.
The third way to take a light reading is to use a GREY CARD (below). A Grey Card is set at 18% grey colour, which is how the camera sees light, so placing a grey card facing the camera will measure the light being reflected onto it.
18 % Grey Card use |
There are different types of light meters available. The one being used above is a DIGITAL Light Meter which houses its own invercone, and is good for ambient,cord or open flash and good fro incident and reflected readings. Other types include ANALOGUE Light Meters which are good for Black and white photography and landscape work where there may be ambient light to measure.
SPOT Meters are expensive, but very effective as very precise tones may be metered individually. These should be used with a grey card for accuracy.
YOUR CAMERA ITSELF ALSO HOUSES IN CAMERA METER MODES including: AVERAGE, CENTRE WEIGHTED, SPOT, MULTISPOT, MATRIX & EVALUATIVE.
