4 This is how the Starlite works
4.1 Incident and reflected light measuring
Your Starlite is designed for the enthusiastic
amateur as well as for professional use.
Its rotating measuring head is the optical "control
center", and the following measuring functions can
be set:
– Incident light measuring, diffuser raised:
spherical measuring characteristics
– Incident light measuring, diffuser lowered:
flat measuring characteristics
– Reflected light measuring with 5° measuring
angle through the viewfinder
– Reflected light measuring with 1° measuring
angle through the viewfinder
Thus, the meter can be conveniently used for all
measuring methods including the zone system.
4.1.1 Incident light – Spherical diffuser
Set "diffuser raised" with the diffuser ring at the
measuring head. The symbol
appears on the
display.
Taking measurements using the incident light
method in particular can produces perfectly
exposed shots. With the incident light mode, the
Starlite measures with its diffuser the incident light
from the subject towards the camera.
This guarantees that the tone quality of the picture
is equivalent to that of the subject.
This is especially important for very bright or dark
subjects. Even under very difficult photographing
conditions, as for example with subjects which
have a lot of contrast, the incident light measuring
method is a much more reliable way of producing
well-exposed and professional pictures.
4.1.2 Incident – Flat diffuser
The lowered/retracted diffuser having a flat
characteristic is suitable for reproductions and
for taking measurements for special lighting tech-
nology and photometry.
For this function, the "diffuser lowered"
with the
diffuser ring at the measuring head must be set.
Note!
☞
When using the incident light mode with
the setting flat diffusor
at the diffusor
ring, the display nevertheless will show the
symbol .
