The processing of original negative film necessitates extreme
care in the mechanical handling of the silver halide emulsion,
and also the elimination of contarAnato (foreign; particles
from the processing environment, if maximum image quality is
to be achieved. ' hhe prime purpose of photography is inter-
pretation of the image, if development is performed in a
contaminated atmosphere, inevitably a degraded negative
results. In this program, it is planned to develop a com-
puterized mathematical model which will predict the quality
of the image in quantized form, given certain factors
describing the image, the film, and the contaminant.
2. At the present time little or no data are available to procurement
agencies and to designers of arrived services photographic
laboratories on which to base a "cleanliness" requirement. One
result of this mathematical r:.-iodel is the evaluation of the
differences between "blacb, gray, white" and various degrees
of "clean" photographic processing roor,-.s as judged by the
quality and interpretability of the image produced in them
Considerable dollar savings may be achieved, if step-do-tvns in
the degree of "cleanliness" of an environment result in none, or
little image quality degradation or minimal image rrisiu terpretationo
Thus, this program will determine the degree of parametric
minimal environmental cleanliness required for any specific
degree of image quality.

Control will be exercised over the contaminant parameters and
observations made of the resultant image quality and readability.

Each image will be judged by 10 ycrvice-trained photographic
interpreters, on a scale from 0 (indicating utter confu;limn)
through 10 (indicating perfect reading). To obtain a uniform

would be correct in assuming that the curve q for a given sot
of factorw is between q and q. The outstanding 50 experi-
mentors would be in error.
2, The "ANOXIA, " or analyu_is of variance, will provide
information as to whether a >ignificant difference in q does,
or does- not, exist due to changer in each factor_a, b, etc.
If it is discovered that any particle factor does not affect
quality (for instance, it is conceivable that particle type, t,
may have no effect), the model may be simplified by the
or;:ission of that factor and its coefficient in upper case (L)0
?
STAT
3) it is anticipated that significant interactions between
factors will be discovered. Thus, possibly for large values
of h, sn_all valuos of s may be degrading, whereas for small
h, even a large size of s may not be degrading. If so, then
in this exarlple, the h-s interaction would be of significance.
