Theatre Design & Technology - May 1967 - 16
The control set of five media used to evaluate whether
patching media would contaminate results was first compared
to its mated sample. The single-sample color media, regardless of elapsed time (6,9,12,18, or 24 hours) showed
no significant difference in the comparison.
In the lavender area three manufacturers' samples are remarkably stable (Fig. 6.8, 6.9, and 6.10). The two remaining samples reveal significant variations that are in inverse relationship to each other. In Fig. 6.6 (special lavender), the deterioration in absorption of orange, yellow and
green is portrayed, resulting in increasingly whiter light as
the steepness of the curve is flattened. In Trials 1 and 2
after 18 and 36 hours respectively, the extremes of this
breakdown in absorption are shown in profile "a" (Fig. 5.1
and 5.1 1). Fig. 6.7 (special lavender) reveals the opposite
effect of deterioration of lavender. In this case it is the
blue area which transmits less light as the time extends
from 0 to 27 hours, while the absorption areas (and the
red also) remain unaffected. The amount of deterioration
is, however, so small for this sample that it might be
placed among the three more stable samples listed above.
Secondly, a comparison of the individual profiles of one in
strument series designed for tungsten-halogen cycle lamps
(ES.46 OK) testing the durability of amber color media, revealed no variation. As one would expect from other very
similar results in this experiment, the range of change was
very narrow, from 2.0 to 3.0% and the time of change was
mainly during the 21 to 24 hour period of the trial.
u
The main objective of this trial, however, centered around
the 500 watt, spherical reflector. Kliegl instrument,
(SF. 56 K). The amber series of color media showed no
significant differences; all profiles were stable over time,
regardless of manufacturer. In the significant area no deviation beyond 5% occurred.
The blue area, in contrast with the other two areas, deteriorates significantly over time in the case of every manu-
