1. Film Coding
Tyson is determining the possibility of'applying film code to archival films and
new films.
-(a) A single border edge along the length of the film will always be
clean and available for coding, however, the choice of which
border is available along the film length is a variable.
STAT
(b) Coding system should be preferably human readable as well as
machine readable.
(c) Cannot'indent or damage film in any way.'
(d) Should be permanent. Removability is not a requirement.
(e) Cannot put code betweeh frames because some negatives may con-
tain strip photography and will have to be artificially split up.
STAT

(f) Should consider the possibility of edge coding (along the 2.5 to 7.5 mm
edge).

recommends consideration of ultrasonic technique.
proposed a meeting be held in Washington soon with our
technical representatives present to resolve the.-problem of
coding compatibility with existing codes in archival films.
2. Masking and Transport '
(a) Masks along the width of the film maybe eliminated in order to
assure the printing of all data on the film.
NGA Review
(b) Masks along the length of the film only for prevention of fogging., not

(c) No discreet frame sizes. -Frame sizes will vary from roll to roll
and possibly within the same roll. Coding will determine the
stopping point-for locating frames in strip photography.

1000' roll capability definitely required for raw stock.
Maximum negative film length will probably be 500'.
(d) Masks to be manually adjusted (automatic feature not required).
?(e) Should have capability of removing partially exposed roll of
3. Reaction to Machine Sketch
(a) Try to limit size to 5 x 7 x 2.5 if at all possible.
(b) Control panel as shown may make access to film area difficult.
Should consider recessing if possible-.
(c) Artist's concept required by October 1, 1964.

Tyson says this is not the problem. Instead, it is.radiation from our machine
to outside undetermined (possibly enemy) sources.
5. Exposure Control, Dodging, Gate
(a) Range of density - no clarification by monitor except that some
films are black and some clear (.05 above fog to 2.5).
(b) Printer will handle high and low altitude films.

STAT (d) No type cleaner in the machine. Preferably vacuum cleaning
of raw TI IM.
(e) Auto dodging - spot size vs. resolution. feels that spot
size must be equal to or?smaller than the i size of the informa-.
tion desired (i.e., 1/400 mm or 200 cycles/mm*modulation) to
maintain resolution. .

? control, dodging-electronics interface with control panel; servo mechanisms,
operation interlocks.
5. Film Coding
Code material and application, location on film, effects on film, permanency
of record, ability to remove or change for correction, clean room contamination,
ease of application; type of coding, techniques for reading, readout logic.
6. Illumination System
Investigation of current and advanced illumination techniques; light versus
film spectrum match; photometry; heat dissipation, contamination considerations,
