Aerial Photographic Data Computer
An aerial photographic coverage and flight planning computer, such as the Aerial Photographic Data Computer Type BM-38A . can assist you with many of the calculations required for mission planning. The aerial photographic data computer contains scales, indices, and information pertaining to frame and panoramic camera photography as well as radar and infrared detection mapping. This computer is a useful tool in mission planning. It can provide quick responses to a number of mission requirements...
Color Correction
Imageediting programs also offer color correction and calibration features. These color correction features allow you to modify an image to get the best possible quality to a color printer or other output device fig. 3-16 . These color corrections are accomplished by using a gamma curve. The gamma curve represents the pixel values in the original image on the horizontal axis. The corresponding values of the displayed image are represented on the vertical axis. Separate red, green, and blue...
Consolidated Master Crossreference List
The Consolidated Master Cross-Reference List C-MCRL is designed to provide a cross-reference from a reference number, such as a manufacturer's part number, a drawing number, a design control number, and so on, to an assigned NSN. Part I of the C-MCRL is designed to assist you in identifying items in the ALTIUUTI Ot iqUIVJOIKT FAITS. VT002 00 ALTIUUTI Ot iqUIVJOIKT FAITS. VT002 00 Figure 5-6. Illustrated Parts Breakdown. Figure 5-6. Illustrated Parts Breakdown. Figure 5-7. Columns of the...
Using Gamma And Contrast Index
For black-and-white ground pictorial photography, a gamma of about 0.65 to 0.90 or a contrast index of 0.56 to 0.60 is adequate for most printing systems. Some printing systems, such as those using specular light sources, require a lower CI. For these systems, a lower value may be more suitable. The best gamma or contrast index for a particular printing system can be determined only through practical tests. These tests can be made by developing several equally exposed films to different gamma...
Types Of Aerial Photography
The vertical and oblique categories of aerial photography are divided into several types of aerial photography. Types of aerial photography are designated by their composition. A PINPOINT aerial photograph contains a target small enough to be included in one exposure. Long, narrow targets are photographed by making a series of overlapping exposures, called a STRIP When several strips are pieced together to form one composite picture of a large area, it is called a MOSAIC. Two pictures...
Oblique Photography
An oblique aerial photograph is made with the camera directed out and down at an angle from the aircraft not straight out and not straight down . For accuracy, the amount of the oblique angle is stated in degrees. The angle between the camera axis or optical axis and the horizontal is called the CAMERA DEPRESSION ANGLE straight out, parallel to the ground, is 0 degrees, and straight down, perpendicular to the ground, is 90 degrees fig. 4-3 . Oblique images may be anywhere between 0 and 90...
Warning
Unauthorized modification or deviation from prescribed life support and survival equipment by individual crew members could create safety hazards. NATOPS General Flight and Operating Instructions, OPNAVINST 3710.7, specifies minimum requirements for such equipment and is supplemented by the naval air training and operating procedures standardization program for each specific model of aircraft. Peculiar configurations or modifications to life support and survival equipment are not authorized....
Sensitometry
In the Photography Basic , NAVEDTRA 12700, training manual, the quality of the photographic product was judged only from its visual aspects. As a further step, you should know of other controlled working methods and techniques that ensure photographic quality. This area of control, or sensitometry, is one method of using certain photographic theories to improve photographs while saving time, effort, and materials. With sensitometry, variations from the standard and recommended corrections are...
Transmission
Most photographic material, even clear film, does not transmit all of the incident light that is relevant to it. Transmission is a measure of the light-passing ability of a film or other medium. The transmission of a processed film refers to the fraction, or percentage, of incident light that passes through the film. In a formula, transmission is represented by a capital letter T. The formula for determining transmission is as follows T Amount of transmitted light Amount of incident light The...
Analyzing Characteristic Curves
By analyzing a characteristic curve, you can determine the effective speed of the emulsion, the contrast, the latitude, and the useful exposure range. Figure 2-6 at the end of the chapter shows a typical characteristic curve with the various parts and their names. Refer to figure 2-6 frequently as you proceed through this chapter. The speed of the material being evaluated determines the position of the curve regarding log exposure log H or horizontal axis. The length and slope of the...
Plotting Characteristic Curves
Once the graph is labeled, use a densitometer and read the densities of the sensitometric strip and plot them on the graph to form a curve. Assume that the sensitometric strip has the following density readings To plot these densities on the graph, find the density value reading of step 1 and place a dot at that point. Do the same with steps 2 through 21, as shown in figure 24. After plotting all the readings, connect the plotted points with a french curve and straightedge fig. 2-5 . You do not...
Feature Picture
A feature picture is a single picture that tells a story. It could be a color or black-and-white print or a transparency. It is quite possible that the end product will be used in the print media, in the electronic media, as an advertisement recruiting, for example , as a news feature, or for photographic exhibition. A feature picture serves a single purpose-to tell a story quickly and clearly. A feature picture is defined as any picture, other than instantaneous news, that informs, entertains,...
Picture Story
The production of a picture story is one of the most exciting and challenging assignments in photography. It is an effective method of telling a story about events that are happening in the Navy. However, a picture story does not just happen it starts with an idea. This idea forms the foundation upon which a story is built. When the idea is sound and you provide good photography, there is an excellent chance of developing a professional picture story. Regrettably, the development of a picture...
Spot News
Spot news is an event that happens without warning and, in many ways, is the most difficult event to photograph-an accident, a plane crash, a fire or tornado-even the unexpected arrival of the CNO aboard your ship. Regardless of the situation, you will be working at top speed and under the pressure of a deadline. Success of your photography is dependent upon how well you handle your equipment, arrange your time, and do your research. Most experienced photographers agree that spot-news...
