11 Practical tips
Pre-programming influence values
The Starlite determines precise exposure data in
accordance with DIN 19010. Should you not be
satisfied with your results, remember that there are
independent factors which can affect the success
of your shot:
For example:
– The "true" speed of your film can differ from
that which is stated on the packaging.
– The "true" shutter speeds of your camera can
be different from the speeds given.
– The "true" apertures of your camera can differ
from those stated.
– Differences can occur in the development of
your film and the pictures.
In addition, there are purely subjective aspects
and the question of personal taste in the evalua-
tion of finished pictures.
However, you can set your Starlite to the particu-
lar features of your camera, the brand of film, your
developing method and your subjective evaluation.
We recommend the following methods:
Take the reflected light and incident light measure-
ments of several normal subjects (grey chart and
color charts are extremely suitable for this) and
make a series of exposures using values given by
your Starlite for each of these on your film. The
first shot is exposed with the exposure data shown
by the Starlite. For the subsequent shots, these
exposure data are reduced and increased up to
one f-number depending on the raster of the lens.
The lighting conditions may not change during
these exposures.
From the developed pictures you choose the
optimal shots, based on your own personal taste,
and compare the data thereof with the measure-
ments. If its turns out that you prefer shots that
were made with an altered value, you can
programme this value into your Starlite via the
function correction value (chapter 8.1, page 27).
