Psychometric Evaluation Of Diazo Reproductions, John A. Kosta

Theses

An experiment was conducted to determine quality criteria for continuous-tone diazo film reproductions. The rank-order method was used to acquire judgement data from a group of experienced photographic scientists evaluating diazo reproductions varying in exposure level and tone reproduction contrast. Analysis of the data resulted in the conclusion that a high degree of agreement does exist between the judges, the quality of a diazo copy depends significantly on the exposure level and the silver positive input, and maximum density and tone reproduction contrast could be possible quality criteria for diazo reproductions.

[Monobath], William Quan

Theses

A monobath designed for Kodak panatomic-X 35mm film was obtained, which produced similar contrast and 2/3 of a stop increase in speed as compared to Haist' s monobath MM-1 formula. Formulation of monobath was based on his formula by increasing the phenidone from 4 to 7 grams, sodium thiosulfate from 110 to 125 grams; pH and temperature were set at 11.0 and 85 F respectively

Subjective Evaluation Of The Noticeable Density Differences In A Continuous Tone Photograph, Barry Buckser

Theses

Eighteen photographs of two subjects, printed on contrast grades numbers 1, 2, and 4, of Kodak Polycontrast paper and mounted on gray, white, and black mount boards were subjectively evaluated to determine the number of noticeable density differences the average observer can see. Objective measurements were made of the noticeable density differences. The noticeable density differences for a continuous tone print were in nine major groupings and four minor groupings. No significant difference was found between the number of densities found on prints of different contrast and different mounts. No significant difference was found between photo graphic orientated and non-photographic …

An Estimation Of Accuracy For Star-Oriented Optical Fixes Of Artificial Earth Satellites Produced By Amateur Equipment, David Weishaupt

Theses

The project's intent is to determine the accuracy of simple amateur equipment in producing optical fixes from a reference star background. A standard 4" x 5" Speed Graphic camera is used with a timing device consisting of a short wave radio and a tape recorder to record the time at exposure. The accuracy obtained from two out of four observations is within 1800 feet along the orbital path of the satellite.

A Latent Image Distribution Study Of "Dry-Writing" Photo-Recording Materials, Joseph Geller

Theses

Improving silver halide emulsions used for the direct writing of oscillographic traces is a topic not discussed openly in the technical literature. It has been previously thought that good contrast between image and background depends upon the extreme low-intensity reciprocity law failure of these emulsions combined with their ability to be desensitized by low-intensity light. Evidence presented in this report indicates that low-intensity reciprocity law failure is very desirable for the surface image; however, for the internal image, the most practical* of the three materials tested reveals no reciprocity law failure within the time interval from IO*2 to 10*6 seconds …

Changing The Contrast Of Ektacolor Paper, Britton Hopkin

Theses

Practical effects (contrast, fog, maximum density, and scale index) on the characteristic curves of Ektacolor paper were found for variations in the concentrations of sodium carbonate, potassium bromide, 6-nitrobenzimidazole nitrate (Kodak AF-71), color developing agent (Kodak CD-3), pH, and citrazinic acid (CZA) in an Ektacolor developer used on the Kodak model 11 drum processor. The effects of pH, citrazinic acid, potassium bromide were found to be significant while the effects 6-nitro benzimidazol nitrate and CD-3 were significant only in isolated insidences.

The Use Of Ektacolor Paper As A Pre-Press Color Proof, Keith Erb, John Suter

Theses

To test the usefulness of Ektacolor Professional Paper as a pre-press color proofing method, one set of three predictor equations for each of the four primary printing inks was derived relating additive exposures on Ektacolor to colorimetric solid ink densities. These relationship would not yield to simultaneous solution.

Chromaticity coordinates of several sets of solid inks were matched on Ektacolor with an error of 2-10 MacAdam noticeability units. Probably because of the differences in surface characteristics of Ektacolor and newsprint, a visual match was not achieved.

A Method Of Calibrating A Photo Optical System For Determining Spatial Relationships, E. Glab, D. Zimmerman

Theses

A technique is described for the calibration of a photo-optical system. This technique yields a response surface. Measurements of image density and image width taken from a microdensitometer trace can be related through this response surface to object dimensions.

A Sophistication Of The "Effective Exposure" Method Of Compensating For The Chemical Amplification Of The Photographic Emulsion As Applied To The Determination Of The Modulation Transfer Function, Lloyd Leiderman

Theses

Known exposures were impressed upon Panatomic-x film by imaging interferometrically generated cosinusoidal intensity distributions of 24, 64, and 96 cycles per millimeter and micro-character istic curves of the material were constructed.

An Investigation Of Photographic Edges In Determination Of Modulation-Transfer Functions, Walter Gramiak

Theses

An investigation is developed for determining whether certain factors, which are characteristics of a photographic edge, are of significance in the derivation of the modulation transfer function of a system from the edge. Factors investigated were edge spread, density range (contrast), and background density. The experiment was limited as to levels used but it was determined that the edge spread significant and a minimum allowable edge spread was calculated.

Minimizing The Effects Of The Relief Image In A Coherent System Through Index Matching, Edward Sklar

Theses

The effect of the relief image in a coherent optical system was minimized by matching the average refractive index of the emulsion ne with that of a liquid of a known refractive index nl. A match of ne and nl was determined by minimizing the intensity of the first side order of the Fraunhofer diffraction pattern of a sine-wave image. A match of ne and nl can be made exactly only when the surface gelatin associated with the silver and the differential tanning effects of development are not present. Under other conditions ne is not homogeneous. The intensity of the …

Melt Rheological Properties Of A Filled Polyethylene, George Lewis Levy

Theses

A procedure was developed to convert shear stress at various melt temperatures into a computed shear stress at a constant temperature in an isothermal system.

The isothermal shear stress was first analyzed at an equilibrium condition before time induced stress reduction for

1) the temperature dependency of shear stress

2) non-newtonian flow behavior

3) a relationship between the independent variables of shear rate, filler concentration and temperature, and shear stress.

A statistical analysis was performed on the data to find an empirical relationship between shear stress and the independent variables, at any time, under stress, for unfilled and filled high …

Ph Effects On Fluorescent Fatigue, Donald Miraco, John Pierce

Theses

Fluorescent dyes tend to fatigue when exposed to short wavelength radiation. Since all work is not done at one pH level, it is necessary to know how a change in pH will effect the fluorescing characteristics of a dye. Of particular interest is the effect on fatigue as a function of time. The shift in spectral absorption with varying pH was established for fluorescein dye. Its increase in fluorescing intensity with increasing negative ion concentration was then measured. With increasing exposure time the pH's of 6.0, 8.0, and 10.0 gave indications of fatiguing while the pH's of 2.0 and 4.0 …

The Determination Of A Set Of Alphanumeric Characters Of Equal Recognizability, Keith C. Donaldson, Harry O. Gough

Theses

An experiment is described whose objective was to determine a set of alphanumeric characters of equal recognizability. Constraints were that the characters be similar in aspect ratio to the conventional tri-bar target, i.e., 5:1, and that they and the surround have a low density difference. Such a set is described, together with the experimental technique and data analysis used by the present authors to evaluate the set. At an alpha risk of 0.10 the set of characters E S 2 3 8 9 was found to have equal recognizability under two varied viewing conditions.

Post Exposure Latensification Of A Multilayer Color Film, Thomas A. Tietjen

Theses

A uniform secondary exposure of low intensity is made to a normal or underexposed primary latent image for approximately 5-15 minutes, to increase the effective speed index. This is first studied from a white light approach similar to that used in single emulsion negative materials.

In addition, the ability to manipulate and align individual layers by selective filtering was also studied. Red, green and blue filters, matched closely to the spectral sensitivity of each layer, were used separately and conjunctively towards achievement of the desired levels of effective speed, contrast, color balance and maximum density.

Latensification by a secondary white …

An Investigation Of The Mach Phenomenon And Its Relation To Visual Image Evaluation, Norman B. Nill

Theses

The Mach Phenomenon*(as perceived on photographic film) is herein investigated as a function of edge acutance, contrast and illumination level for the purpose of determining its probable effect in the area of visual image evaluation. The results indicate that dark Mach band widths increase as acutance decreases and dark band width is independent of contrast and illumination level while light band widths remain constant, over the ranges investigated. Using these findings as a basis, a dark band width predictor equation was found, taking the form; dark band width (in microns) =K/acutance, when average edge gradient is the measure of acutance. …
