ABSTRACT

A color film with a sensitivity and color balance equal to SO-368,Kodak MS Ektachrome (Estar Thin Base) was required for use on the Apollo-Soyuz Test Project. A Wratten 2A filter was required for use with thefilm to reduce short wavelength effects which frequently produce a bluecolor balance in aerial photographs.

This report documents the background regarding a special emulsion which

was produced with a 2A filter equivalent as an integral part of an SO-368 filmmanufactured by Eastman Kodak, the cost for production of the special film,and the results of a series of tests made within PTD to certify the filmfor ASTP use,

The tests conducted and documented were physical inspection,process compatibility, effective sensitivity, color balance, crosssection analysis, resolution, spectral sensitivity, consistency ofresults, and picture sample analysis.

BACKGROUND

The Apollo-Soyuz Test Project (ASTP) scheduled for mid-year 1975 has requirements

for photography of the Earth's surface from the Apollo-Soyuz spacecraft. ProjectMA-136, Earth Observations and Photography, requires the use of color photographywith oblique looking 70mm Hasselblad cameras to support the observation programof Dr. Farouk El Baz.

Photography of the earth from very high altitudes necessitates considerations of

the effects of the atmosphere on light travellig, through it from the subject to

the camera. These effects are well dQcumented ( (2) with perhaps the best

description being in Color Science (3). The net effect is a predominance of shorterwavelength radiation which causes a blue veiling in uncorrected color photographs.Correction of this problem is routinely accomplished through the addition of acamera filter such as the Kodak Wratten 2A (Figure 1).

FIGURE i. Wratten 2A Filter

It was determined during photographic planning for ASTP that Wratten 2A or shortwavelength blocking filters for the Hasselblad cameras were not in the approvedflight hardware inventory. It was also determined that procurement of the properfilters and check-out for approval as flight hardware would be difficult due toscheduling.

-2-

PTD proposed an alternative to the camera filter which would produce the same photo-graphic effect in the imagery, this being to "coat" a filter directly on the filmto be used. The decision was made to adopt this technique for providing properfiltration with the SO-368, Kodak Ektachrome MS (Estar Thin Base) Film to be usedon ASTP.

This report is a review of available information regarding the filter coating tech-nique, a comparison of cost information and documention of test results on thespecially coated SO-368 film. The film has been designated QX807 emulsion 1-32 byEastman Kodak.

-3-

TECHNIQUE

The available techniques for filter coating a photographic film include (1) a dyeabsorption coating added to the emulsion side surface of an existing film stock and(2) an absorption dye addition to the film overcoat during the film manufacturingprocess.

A normal photographic film, as manufactured, consists of numerous separate anddistinct layers, each with a well defined use in the final product. Typicalof these layers for a color film might be :

o the anti-curl coating

o an antihalation coating

o the film base

0 a minimum of three light sensitive layers

o a yellow filter coating to correct dye characteristics

o a protective overcoat

Each layer incorporates different chemicals and materials. The technology forcoating these layers is highly developed and routinely accomplished by photo-graphic and thin film manufacturers.

Tech/Ops, Inc. of Burlington, Massachusetts was notified of the requirement for anultraviolet absorption overcoat on SO-368 film for ASTP and responded with a briefproposal 4). This company had performed a similar service under Contract NAS9-8240 completed in 1968. The Tech/Ops technique required the addition of dyes tothe surface of an existing film type. Three dye types were cited in their letterof 14 November 1974, reference: proposal 5204550. These dyes were available from Ciba-Geigy, GAF and American Cyanamid.

Eastman Kodak, the film manufacturer for the scheduled ASTP SO-368 film, later agreedto provide the film with dyes added during manufacturing which would approximatethe addition of a Wratten 2A filter. This alternative was selected by PTD repre-sentatives as the best for several reasons.

0 Eastman technology for accomplishing this has been demonstratedand is in current use. SO-242, High Definition Ektachrome AerialFilm, also scheduled for use on ASTP is manufactured with a coated"yellow filter". SO-242 has been successfully used in space on

-4-

the Skylab program and has been used on the Earth Resources Air-craft Program in aircraft flown at altitudes from 20,000 to 60,000feet. Previous experience resulted in high confidence by PTD inEastman Kodak filter coating technology.

o The coating could be accomplished by technique number 2 as an integralpart of the film manufacturing process necessitating no additionalcoatings.

o The cost was significantly less when accomplished at the manufacturingstage and no added time was necessary for an additional step in theASTP film preparation.

The film with the filter overcoat was purchased from Eastman Kodak and subsequentlydelivered to NASA in March 1975.

-5-

COST

The costs incurred for producing the special SO-368 film for ASTP were a total of

$11,296.38 (less 4% discount). This included 200 rolls of film 16mm x 158 feet,22 rolls of film 35mm x 200 feet and 36 rolls of film 70mm x 400 feet in length. The

charge for the coating process called a "set up charge" was $4000.00.

This cost is compared to a proposed Tech/Ops cost of $13,627.00 for coating 1000 feet

of 70mm film. NASA was to provide the film for coating.

The quantity of film when it is a special order film (SO prefix) is somewhat determined

by the fact that an entire coating or 4000 square feet minimum of film must be purchased.The width, length and perforation may be specified by the buyer with a plus or minusten percent quantity guaranteed by Kodak. This is the reason for the excess quanti-ties of film type QX807 (coated SO-368) ordered.

-6-

TESTS

Although PTD was highly confident in the process used for manufacturing the QX807 film,a series of tests were designed and implemented to check the new film both to determineits characteristics and to certify it for ASTP use.

These tests included:

o Physical inspection

0 Process compatibility

0 Effective sensitivity (Speed)

o Color Balance

o Cross Section Analysis

o Resolution

o Spectral sensitivity

o Consistency of Results

o Picture Sample Analysis

These tests were conducted using another SO-368 emulsion for cross referencewhere applicable.

The tests and results were as follows.

Physical Inspection

A physical inspection of randomly selected sample rolls of each roll width, 16mm,35mm and 70mm, was made. The inspection is designed as a check for manufacturinganomalies including emulsion defects, dirt, scratches, edge smoothness and coatingevenness.

The surface of all QX807 was completely clear of dirt and scratches. The edges weresmooth and the base and emulsion surfaces appeared evenly coated. One emulsiondefect was found near the end of a 400 foot roll of 70mm film. This defect was apinhole less than 1 millimeter in length with dark streaks about 7.5 centimeters inlength and 2.5 centimeters in width. Although objectionable, it is not uncommon tofind such defects on photographic film. These defects represent some very smallpercent-of the total surface coated.

-7-

Subsequent defects have not been found on any of the film.

Eastman Kodak was contacted regarding the occurrence of the anomaly and was requestedto review its quality control results from the QX807 emulsion. The manufacturer'sresults indicated that this particular emulsion was exceptionally defect free and selectedfor NASA because of an awareness of its important space application.

The thickness of QX807 was determined to be 0.0035 inches which was the same as thethickness of 70mm SO-368 emulsion 18-32. The appearance of the two films was also identical.The film was considered physically acceptable.

Process Compatibility

The QX807 film was processed by PTD in its Houston Ektachrome Film Processor inKodak ME-4 chemistry and in the 1811 Versamat Ektachrome RT Processor using KodakEA-5 chemistry to evaluate process compatibility. Resultant sensitometric curvesare attached here as Appendix A.

The film was found to be compatible with either process producing results which wereacceptable when speed and color balance were evaluated.

The curves produced in the Versamat were superior to those produced in the Houston,therefore the 70mm ASTP QX807 flight film will be processed in EA-5 chemistryby the 1811 Versamat.

It was also found that machine speed control in either machine was easily achievedwhich would make it operationally easier to meet flight film processing controlstandards.

Effective Sensitivity

The effective speed of QX807 was evaluated by exposing the film with a calibratedsensitometric exposure using the PTD I-B sensitometer. Exposures were made usinga 28500K lamp filtered to a 55000 K color temperature and 1/50 second exposure.

The exposed films were processed in the Versamat and Houston processors, the densitieswere read using the MacBeth TD-504 densitometer and the results recorded. The curvesare included in Appendix A.

Using the Southard Speed method which derives an equivalent ASA speed the results wereas follows.

Machine Film Machine Film

11 57 11 61

Color Balance

The color balance or the relationship of the red-green-blue sensitive layers in the

film was evaluated using the sensitometric results achieved above and shown in

Appendix A.

Color balance with the Versamat operated at nine feet per minute and the Houston

operated at ten feet per minute where the approximate proper equivalent ASA speed

was achieved were compared. The Versamat results show the red and green sensitive

layers with good balance from toe to shoulder and the blue layer sensitivity about one-half

stop slower at points through the curve middle or straight line. The Houston curve shows

a greater separation between the red and green layers, a slightly more dense toe area and a

blue layer sensitivity one-half stop slower. The slower blue layer indicates that the

dye additions are absorbing some of the shorter wavelength radiation before it exposes the

blue layer as designed.

The Versamat curve is excellent. This curve or one very similar will be established as

an ASTP control curve.

Cross Section Analysis

Cross sections of QX807 and a reference S0-368 emulsion 18-38 were cut using the PTD

Leitz microtome and examined in a microscope. Photomicrographs are shown in Figure 2.

Subjectively, the two films appear to be very similar. The cyan, magenta and yellowdye layers, the base, an adhesion layer and the overcoat layer (over the yellowlayer) are all visible. A relative scale included for reference shows the thicknessesof the two films to be very similar.

The overcoat layer in the QX807 has better defined edges on the microtome than thereference emulsion, but this may be a function of either the microscope illuminationrelative to the sample position, or the filter characteristics of the dye additivesin the QX807.

No significant differences were found between QX807 and the reference SO-368 films.

Resolution

Resolution of QX807 was checked by exposing a master USAF 1951 resolution targetonto the new film and reference film using the PTD microcamera.

An exposure and camera focus series were conducted to determine optimum settingsand the results were processed in the 1811 Versamat.

Results showed a resolution of 63 line pairs per millimeter for QX807 compared to71 line pairs per millimeter for the reference. The QX807 was considered acceptableon the basis of resolution tests.

-10-

Spectral Sensitivity

Exposures were made on QX807 and a reference S0-368 emulsion using the PTD MeadSpectrum spectral sensitometer. This instrument places an exposure with wavelengthsvarying from 350 nanometers (nm) to 1000 nm with 11 levels of intensity attenuationat each wavelength.

Integral to analytical density conversion matrices for S0-368 are not available inPTD therefore the results were evaluated subjectively using the samples includedas Figure 3.

FIGURE 3a. QX-807 SpectralSensitometry

FIGURE 3b. S0-368 SpectralSensitometry

-11-

The effect of the dye absorption in the QX807 emulsion may be noted by exposureattenuation below 400 nm compared to SO-368. This result may be compared to thetransmission characteristics of a Wratten 2A filter shown in Figure 1.

Consistency of Results

Consistency of density and color produced by equal exposures was evaluated by making aseries of 16 spectral sensitometric exposures on a 100-foot section of 70mm QX807, pro-cessing the film in the 1811 Versamat and reading the densities at three wavelengthsusing the MacBeth TD-217 densitometer with a visual filter.

The results, in density units:

500nm 650nm 570nmLevel 1 Level 1 Level 40,54 0.89 0.970.53 0.89 0.970.53 0.89 0.950.53 0.89 0.970.53 0.89 0.980.53 0.89 0.960.53 0.88 0.950.53 0.88 0.97.0.52 0.88 0.960.53 0.89 0.980.53 0.88 0.940.53 0.89 0.970.53 0,89 0.950.53 0.88 0.950.52 0.88 0.950.53 0.88 0.94

The results were within plus or minus 0.02 density units (densitometric readingerror) at the three levels read and recorded.

This data is consistent with the observations made in the physical examination,with sensitometric evaluations and with picture sample analysis.

Picture Sample Analysis

Perhaps the ultimate proof of any film is a subjective evaluation of sample photo-graphs taken under conditions simulating actual anticipated use.

-12-

QX807 was exposed in Hasselblad cameras by astronauts on T-38 aircraft trainingflights and by PTD personnel on ground tests.

Based on sensitivity data generated above the film was exposed to a variety of targetsand the results were examined. A slight yellow color balance was obvious on

ground targets and less-than-normal blue was observed with aerial scenes.

PTD made tests to "print-out" the effect of the yellow filter (short wavelength dyeabsorption layer) should non-earth looking photographs be made where atmosphericeffects would not be present. This was accomplished with routine laboratory colorbalancing techniques.

-13-

CONCLUSION

The QX807 film (SO-368, Kodak Ektachrome MS,(Estar Thin Base) with an equivalent

Wratten 2A filter) was found to be acceptable for ASTP use and was certified for such

use (5).

The sensitometric characteristics of this emulsion are superior and high quality spacephotographs should result if other influencing parameters are controlled.

QX807 is similar in many ways to either SO-242 and SO-356 with the exception of reso-

lution and should be considered a reasonable replacement where greater film speed is

important.
