welcomed all to the first meeting of the Ad Hoc Committee for 3-3
Systems Capabilities. II reviewed the basic purposes of the committee and
2 5X1A_ the guidelines within which the committee is to operate. The committee was
established to:
1. Analyze and evaluate the effectiveness of photographic flight
and processing experiments performed within the Program.
2. Recommend standard future 0 photographic configurations
25X1A
resultant from the experimental program; and
25X1
25X1
3. Recommend additionallIphotographic flight and processing 25X1
experiments.
pointed out that.one of the most important functions of the committee
was to insure proper community support for the flight test program, and to
insure that the results of the program were properly made known to the in-
telligence community. The membership of the committee had been specifically
constituted to this end.
25X1A --Test Plan

reviewed the basics of the test plan as it was currently en-
visioned. These plans are as follows:
1. Filter Evaluation (CR-1, CR-2, CR-3)
Basic Objective
To evaluate the photographic difference between W/21, W/23A,
and W/25 filters.

Evaluation
JT4767AQ0 300050007-5
The evaluation here is primarily subjective, looking basically
for differences in image quality and the trade-off in atmospheric
attenuation vs. exposure time.
Discussion
questioned the necessity for more filter tests. He pointed
out that several filter tests have been done in the past on both
and other systems. II pointed out that J-3 was essen-
tially a new camera and that previous filter studies on J-1 were not
directly valid as the trade-offs were now different. ==agreed
that this was true. It was further discussed, and agreed, that
other filter tests may now be warranted. The committee tasked
to look into this and make recommendations.
2. Exposure Analysis (CR-1, CR-2)
Basic Objective
Determine what effect a range of 1 1/3 stops has on operational
photography.
Evaluation
The evaluation is planned to be b.a h G,biecti_v-e_an_d-oWect ve.
NPIC will be asked to perform the subjective analysis. NPIC is
also making microdensitometer traces of the COMIREX HPL targets,
for quantitative exposure analysis. This data will be compared
with the normal mission density (terrain) analysis to evaluate the
relationship.
Discussion
25X1A
It was generally agreed that the work was proceeding in the
,proper direction. Ii questioned the relationship of this work
to Pro ect0 It was agreed that the two were complementary.

L agreed to arrange for the ProjectOreports to be provided

Basic Objective
Test the operational feasibility of obtaining bi-color
photography from mission photography.
Evaluation
a. Obtain the best bi-color prints possible.
b. Evaluate the quality of the green (SF-05) imagery.
c. Test best method of obtaining bi-color images.
Discussion
Considerable discussion was generated relative to this subject.
The highlights of the discussion were:
a. questioned the need for this test. It was his
opinion that there was not much use for this technique.
reviewed the memorandum received from OSI on the potential uses
of bi-color. It was generally agreed that even though the ul-
timate use of bi-color is not clear, it is worth testing.
b. The question of impact on operational photography, if
the SF-05 filter got stuck in the primary position, was raised.

pointed out that= block testing of CR-2, in this
regard, indicated no loss in resolving power between the SF-05
and the primary W/21 filter. The committee then agreed that
the test should be run.
c. questioned the speed with which we would be
able to ge necessary rectified and ortho-printed dupes from
the ON. 0 agreed that the ON's could be sent to ACIC.
agreed to coordinate this activity to insure speedy
d. 0 pointed out that, as we presently see it, the
main use of the bi-color technique is as a Spectral analysis
tool, for comparative PI purposes, rather than to make color
prints, and this is what our analysis should concentrate on.

Basic Objective
Determine the effectiveness of a polarizer as a haze-cutting
filter.
Evaluation
a. Image Quality Analysis
b. Atmospheric effects as a functioning solar altitude
and azimuth.
c. Determine effective filter factor.
d. Subjective analysis of tonal rendition.
Discussion
25X1
25X1A General agreement was reached on the desirability of this test.
Oreported that he has been doing some work on the polarization
of ground objects and finds that some objects are highly polarized.
The uses on polarization for this kind of work should be investigated.
2 5X1A. were asked to work together on this potential use
and make recommendations.
5. SO-230 (CR-2)
Basic Objective
Compare 50-230 with 3404 in an operational mode.
Evaluation
a. Compare image quality of SO-230 and 3404. Evaluate
desirability of using SO-230 in J-l and J-3 missions, predict
performance.
b. NPIC to do a subjective evaluation of PI suitability
of S0-230 vs. 3404..
Discussion
Very little discussion. All agreed that this was an important test.

Special Filter (CR-3)
Basic Objective
Determine if a real gain in image quality can be obtained by
using a different spectral band with the second generation Petzval
lens.
Evaluation
a. Image quality.
b. Subjective analysis.
Discussion
pointed out the basic purpose of this test. This filter
25X1A
.25X1A
cuts off at both the short (about 530 mu) and the high end (about 690
mu)_ of spectrum. Lab testing has shown that the MTF of the Petzval
(2nd gn) in the far end is very poor, and that current filters pass
this region. Cutting off this longer region should help performance
optically, and lens tests have indicated that this is the case.
~ointed out that 0 is currently having problems making
this filter. The difficulty is not in the coating, but rather, with
the glass substrate. Work will continue.
7. S0-380 (CR-3)
Basic Objective
Test S0-380 in the 3-3 system.
Evaluation
a. Image quality.
b. System performance (tracking, resolution variability).
c. Lab tests (chamber).
d. Limited dimensional stability analysis.

CR-5. Discussion was held on our confidence of SO-380 in the J-3
system. discussed the extent of lab testing, and its success,
25X1A and verfied that there was very little doubt that SO-380 could be
used. pointed out that =was doing work on the dimensional
stability characteristics of 50-38Q. It was agreed that a summary
of this work should be included in this report. When appropriate,
25X1A time-wise, will prepare such a summary.
8. SO-180 (CR-4)
Basic Objective
To obtain sample satellite photography with SO-180 (camouflage
detection color film).
Evaluation
a. Subject analysis by NPIC of information content.
b. Tone reproduction at satellite altitudes.
c. Image quality (system) relative to 3404.
Discussion
.25X1A
It was agreed that this was one of the more interesting, and
potentially useful, tests. 0 pointed out that the aging of
the S0-180 is critical. He stated that SO-180 is very dependent
on the time after making at which it is used, and that is should
only be used within a certain time period. The problem rests mainly
with the IR sensitive layer which changes speed rapidly as it ages.
More discussion is to be held on this at a later meeting for CR-4
planning.
9. SO-340 (Night Photography)
Basic Objective
Determine what kinds of activity can be detected at night.
Evaluation
Primarily subjective to compare day coverage with the night to
isolate kinds of activity that can be detected.

Discussion
discussed the potential difficulty in running this test
in thel system. The difficulty being primarily one of static
marking, S0-340 is 100 times faster than 3404 and is, therefore, con-
siderably more sensitive to static marking. It was pointed out that
we may have to back off to a 3401 or 3400 type of film and do a "sun-
line" test instead of a direct night experiment. II mentioned that
chamber tests were to be run with QR-2 at 0 and that we should wait
for those results.
