Cibachrome testing

The use of Cibachrome products as a solution to problems encountered when contact printing Kodak film type SO-397 onto Kodak Ektrachrome color reversal paper type 1993 is investigated. A roll of aerial imagery consisting of Kodak film types SO-397 and 2443 was contact printed onto Cibachrome and Kodak materials and compared in terms of color quality, resolution, cost, and compatibility with existing equipment and techniques. Objective measurements are given in terms of resolution and sensitometric response. Comparison prints and transparencies were viewed and ranked according to overall quality and aesthetic appeal. It is recommended that Cibachrome Print material be used in place of Kodak Ektachrome paper because it is more easily processed, the cost is equivalent, and it provides improved resolution, color quality, and image fade resistance.

Skylab 1 (1/2) sensitometric summary

Sensitometric data obtained from all rolls of Skylab 1 original film containing sensitometric exposures applied by the Photographic Technology Division are presented. A summary is provided that identifies the supply and take-up magazine numbers, the amount of radiation, and the change in Dmax or Base + Fog due to heat and radiation for each roll of original film.

Fog tests performed at Kennedy Space Center on Kodak film type 101-05

Based on the tests which were conducted, the fogging exhibited by the Kodak 101-05 glass plates when used in the Skylab S-183 experiment carrousels is a chemical fog caused by an outgassing within the carrousel. Testing has not yet been able to determine which chemical causes the fog or just what can be done to eliminate the problem.

Apollo 17 photographic processing control document

The control parameters are defined which are to be used by the Photographic Technology Division for the processing of all films flown on Apollo Mission J-3. The procedures necessary for establishment of processing control are given along with information for denoting and solving any problem areas or conflicts which may occur prior to the mission.

Kodak film type SO-394-4-1 mottling and hypersensitization test

A number of tests were conducted to show the effects of various environmental conditions in terms of mottling and hypersensitization on Kodak Film type SO-394-4-1. The first two weeks of environmental testing is described, along with the test plan and matrix.

Analysis of DuPont and Kodak duplicating films and chemistries in a Fultron spray processor

A test program was conducted with duPont duplicating film type SR 112 and SCOLOR developer and Kodak duplicating film types 2430, 2422, and FE 2628 (SO-467) and MX-641 developer to determine sensitometric and image quality characteristics of these materials when used with a fultron spray processor. The test results show that the SCOLOR developer foams excessively in the fultron processor when used with or without the addition of an antifoaming agent. The Kodak type FE 2628 film with MX-641 chemistry had the longest linear Log E range at a 1.0 gamma. Sensitometric curves and granularity traces for all film process combinations tested are included.

Separation negatives from Kodak film types SO-368 and SO-242

Two master resolution friskets were produced on Kodak film types SO-368 and SO-242. These target masters consisted of 21 density steps with three-bar resolution targets at five modulation levels within each step. The target masters were contact printed onto Kodak separation negative film, type 4131, using both a contact printing frame and enlarger as one method of exposure, and a Miller-Holzwarth contact printer as the other exposing device. Red, green, and blue Wratten filters were used to filter the exposing source. Tray processing was done with DK-50 developer diluted 1:2 at a temperature of 70 F. The resolution values were read for the SO-368 and SO-242 target masters, and the red, green, and blue separation negatives.

Special processing of Apollo 16 Pan Camera film

Due to the exposure conditions of the Apollo 16 Pan Camera imagery, a series of tests were run to determine if it was possible to: (1) maintain toe speed to preserve the normally exposed near-terminator imagery, and (2) retain an acceptable density range for the two stop overexposed portion of the imagery. A set of processing conditions (80 F, 15 fpm) was found which provide a significant improvement over the Standard Apollo 16 Control for Film Type 3414 in meeting the requirements.
