Review of Mission 1103 Bi-Color -
25X1.A
gave the COMIREX a Bi-Color status briefing on
6 June 1968. They were advised. that the exploitation techniques
employed to date have not been as successful as originally
anticipated, and that as a result of a meeting held at NPIC
on 5 June 1968, a redirection of effort has been established. 25X1A
A three-man National Committee composed of
CIA, Chairman; NPIC Photo Interpreter; an
NPIC/TSSG was established to review the Bi-Color
analysis procedure and to report the suggested equipment, technique,
and procedure for analyzing Bi-Color to COMIREX by 1 August 1968.
The National Committee is not willing to accept orthoprinting as
the best technique without first looking at all available equipment.
Therefore, the National Committee report will probably be delayed.
As a result of the 5 June community meeting held at NPIC,
ACIC has been tasked to attempt orthoprinting with an optical
device known as GZ-1 vice the electronic scanner orthoprinter
AS-11C (See Attachment 1). Also, AMS has tried the Unimace
printer. _ suggested that Bi-Color prints be attempted with
the Electronic Color Printer at Westover Air Force Base.

Questions
1. ~-What is the best method of gathering Bi-Color
information from a PI standpoint? Answer--The ARES has the
advantage of being a real time device, but is not economically
feasible and results in a resolution loss. A group of ARES
machines is not considered a suitable solution. However, a
combination of equipment will probably always be needed and
the ARES is promising because of the real time advantage.
2. What schedule has the National Committee
or others concerned developed for Bi-Color analysis?
Answer--The National Committee was originally to report
by 1 August, but that date will probably not be met due to the
various equipment to be tested.
25X1A prepared a TWX (as a result of the 5 June
community meeting) that tasked DIA /AMS and DIA /ACIC to
25X1A perform some additional work and report within six weeks
following DIA approval. )riginally advised COMIREX
that the 1 August date selected for the National Committee
report was extremely optimistic.
Discussion
It was concluded that those involved with Bi-Color
exploitation are extremely interested in making the technique
a success. A healthy attitude is being maintained by all concerned.
Final Review of Exposure Report 25X1A
The problems associated with finalizing the exposure
report have been solved. The report, J-3 Systems Capability
Report No. 2, is scheduled for distribution to the community on
21 June 1968

Evaluation of SO-230 on Mission 1102, 1046
25X1A
A TW giving the results of the NPIC
analysis of SO-230 has been prepared for the community. In
brief, the characteristics of SO-230 and 3404 were found to be
comparable under in-flight conditions with the exception that the
speed of SO-230 is twice that of 3404.

is experimenting with a change to the curl characteristics of
S0-230 to make it match the curl of 3404. Also, -reports
that the emulsion lift-off problem has not been solved. Further
SO-230 comments will be made by at the 1103 PET
meeting, _ reiterated that SO-230 will not again be flown until
the emulsion lift-off problem is solved.
Evaluation of Wratten 12 :-'ilter on Mission 1103 -
Four passes of Mission 1103 were scheduled to have flown
with the Wratten 12 filter. Due to an operational priority, only
two passes were taken. These two passes were both 60 to 70 per
cent obscured by weather. It is concluded that more data will be
needed for a final analysis of the Wratten 12. This topic will be
considered at the next Ad Hoc Committee Meeting.
25X1A - described tha planned targets for the SO-180 evaluation.
These fall into three basic categories-
Evaluation of SO-380 on Mission 1103 - 25X1A
A tag on test strip of SO-380 was flown on Mission 1103.
Time has not permitted a thorough analysis; however, preliminary
results show no difference between the SO-380 and 3404. Pending
final analysis, NPIC will advise the community of their findings by
TWX. 1105 is now scheduled for a full load of SO-380 with a tag on
strip of SO-121 in one instrument.
Flight Plans for Mission 1104 -
25X1A
25X1A
25X1.A
25X1A _ advised that 1104 will be flown with a Bi-Color capability
and will have a 1600 foot tag on strip of SO-180 on one instrument.
The 3400 sun line test is postponed until winter. See Attachment 2
25X1A for J-3 test plan. He confirmed thatI11111111111111111111111111111was arranging for the
proper filters for SO-180 and requested that-insure that the
horizon camera have the appropriate alternate filter for SO-180.

Special Briefing (arranged bv= On Use of Polarizers
25X1A
With Color Films - 25X1A
briefed The Ad Hoc Committee
on their work with polarizers and color film.
Approximately a year and a half ago, 25X1A
processed material from Air Force flight tes s. Looking a- is
material, the Air Force concluded that the polarizer was of
25X1A zero value. physicist studied the atmospheric
particles and spectral problems and concluded that the Air Force
had failed to achieve results with the polarizer because it was not
oriented in the proper plane. Independent flight tests by_ 25X1A
25X1A show that the polarizer does enhance imagery under
certain conditions. Rayleigh scattered particles (molecules)
are especially susceptible to polarizer filters. Aerosal particles
are of various composition and size and contain only a small
percentage of polarized light. The polarizer is least helpful
with aerosal particles. The polarizer film is especially helpful
when shooting long-range oblique photography into the sun and is
ideal for penetrating water. For operational use, 25X1A
has developed an automatic sensing device that properly orients
the polarizer filter. The physical size of this device is approximately
25X1A 411 by 4". Th aircraft will be used to conduct
some SO-180 tests un er an existing OSA contract. 25X1A
25X1A - are coordinating.
As a separate topic, confirmed that the
Electric Color Printer at Westover will accept an input as large
as 9" by 9" and will produce an output as large as 20" by 2011.
Each copy is individual, thus the last takes as long as the first,
that is, approximately six minutes.

5. All previous action items are closed with one exception.
Attem is to locate the -reports have not been successful. 25X1A
is taking this action item.
The previous minutes reported that 113400 with the appropriate
processing would equal the speed of 3401. The added advantage 25X1A
is that 3400 is of finer grain. pointed out that the appro-
priate processing refers to "a special process only on the versamat"
and asked that this statement be added to this minutes for
clarification.
