11 Practical Tips
Programming Influencing Quantities
Your STARLITE 2 ascertains precise exposure data in
accordance with DIN 19010. In the event that you’re
not satisfied with the results, keep in mind that there
are related influencing quantities which may effect
how well your image recordings turn out, for example:
“Actual” film speed may differ.
Your camera’s “actual” shutter speeds may deviate
somewhat from the nominal values.
Your camera’s “actual” f-stops may differ from those
specified.
Deviations may occur while developing negatives and
prints.
And all of this is compounded by subjective factors
and personal taste when evaluating finished pictures.
However, you can adapt your STARLITE 2 to your
camera’s individual characteristics, your workflow and
your own subjective evaluation criteria.
We recommend the following method: Carefully
measure several standard objects (gray charts, gray
step wedges and color charts are very well suited to
this end) after performing object and incident light
measurement, and complete a series of exposures for
each using the value ascertained by your STARLITE
2. The first image is recorded with the exposure value
displayed by the STARLITE 2. This exposure value is
increased or reduced by up to one f-stop for the
following images, depending upon lens resolution.
Lighting conditions must remain unchanged during
recording of all images. Pick out the best image from
the developed or printed pictures according to your
taste, and compare its data with the measurements. If
images recorded with a changed value look better to
you, you can program the corresponding value into
your STARLITE 2 with the help of the correction
values function (see section 8.1 on page 27).
