Camera Stabilizing Systems

By John Jurgens Cinema Products Corporation Modern camera stabilizing systems enable a camera operator to move about freely and make dolly-smooth hand-held shots without the restrictions or the resultant image unsteadiness encountered with prior methods. These systems transfer the weight of the camera unit to the operator's body via a support structure and weight distribution suit. This arrangement frees the camera from body-motion influences. It allows the camera to be moved by the operator...

The plane of focus of this lens can be tilted in any direction (including vertical and diagonal) as well as horizontal by adjusting the rear lens rotating mount. If the lens focus is set on an object near the center of the field of view, the plane of focus can be tilted so that objects (left side of frame and or right side of frame) located along this tilted plane of focus will also be sharp. If there is not an object near the center of the field of view, measure the distance to the near and...

Screen Types and Lighting Backlit screens

A perfect blue backing would expose only the blue-sensitive layer of the color negative. Crosstalk in the negative layers, imperfect illuminators, and spill light on the set all compromise this ideal. Nevertheless, thanks to the joint efforts of the visual effects community and film manufacturers, the best current combinations of screen illumination and negative type yield backings of unprecedented qual-ity. Either of two types of blue backings can be used in the blue-screen matte process. If...

Pan Tilt and Zoom

It is possible in front projection to pan and tilt the camera during photography, provided that the x, y, z relationships of the nodal points are maintained. To do this, it becomes necessary to use a nodal-point camera mount that permits the front nodal point of the camera lens to be located at the center of rotation for both pan and tilt motions. This requirement of maintaining a co-location of projector and camera lens nodal points also applies to a zoom lens. Because the front nodal point of...

Special Techniques Aerial Cinematography

Motion pictures often require scenes photographed from the air, principally utilizing fixed-wing planes and helicopters. In addition, there are occasional demands for shots made from gliders, balloons, and while skydiving. Many fixed-wing aircraft have been adapted for various camera mountings. When photographing air-to-air it is necessary to consider which camera aircraft is correctly matched to the aircraft being pictured in regard to safety, speed and maneuverability. The cinematographer...

Cinematographic Systems

Most films produced for theatrical presentation are photographed in one of the systems intended for projection in an aspect ratio greater than 1.33 1. These are loosely categorized as wide screen systems. All films produced for use in television systems and most of those produced for industrial and educational use are photographed in an aspect ratio of 1.33 1. Following are the photographic systems currently employed in the preparation of motion picture negatives or reversal originals from...

Zero Cut Editing

To completely avoid the possibility of jumping splices, the negative can be cut into A & B zero-cut format. The zero-cut method, with a minimum of four frames for an overlap, will eliminate the splice-jump problem, but 16mm contact prints made from zero-cut negatives will have a one-frame dissolve at the scene changes. Quite often this dissolve is noticeable when viewing the print. Since Super 16mm contact prints with sound cannot be made directly from a Super 16mm negative, there is no...

Sound Recording Hints

Before embarking upon any recording, it is mandatory to check out thoroughly all of the equipment that will be used. People often have difficulties in the field which could have been avoided if every piece of equipment, including the cables, had been completely checked before leaving for work. If one is uncertain about the use or performance of the equipment, ask for a technician to be available to explain everything and to verify that all of the individual components are operating correctly....

Incident Light Meters

These meters are normally used at the location of the photographic subject. They measure the light which is effective in illuminating the subject. They give an answer in terms of f-stop or T-stop for the camera lens. The camera lens diaphragm opening is then set to match the effective intensity of the prevailing illumination. When the film is exposed, the various reflectances presented by the subject will then each fall into a given place in the film acceptance range. For example, a face tone...

Filter Factors

Many filter types absorb light, and this must be compensated for when calculating exposure. These filters are supplied with either a recommended filter factor or a stop value. Filter factors are multiples of the unfiltered exposure. Stop values are added to the stop to be set without the filter. Multiple filters will add stop values. Since each stop added is a doubling of the exposure, a filter factor of 2 is equal to a one-stop increase. Example three filters of one stop each will need three...

Black White Films

Printer Points

The laboratory controls print density and color balance by increasing or decreasing the intensity of each primary color of light in steps called printer points. Since the development of the B amp H model C printer most manufacturers have standardized on a range of 50 light points in 0.025 Log E increments. In addition to the light points each printer usually also has 24 trim settings 0.025 Log E , giving an available total of 74 lights. The ideal settings for scene-to-scene timing would be at...

Cine Zoom Lenses on Video Cameras

Now that the video medium has progressed to state-of-the-art equipment, where gamma and other picture qualities are controllable enough to provide the film look, cinematographers are finding a need for a greater variety of lenses to render the same quality images they have photographed on film. Unfortunately, professional television equipment manufacturers have not produced many extreme type lenses and therefore there is an urge to utilize the great variety of cine lenses on video cameras. Cine...

Forced Development of Color Films

With the color films most commonly used today, it is possible to compensate for underexposure by extended development or pushing. Similar to the principles of traditional black amp white sensitometry, forced development of these color films increases their contrast, graininess and the fog level. Therefore, forced development can never yield the same image quality possible when films are exposed and processed strictly according to the manufacturer's recommendations. In many instances, however,...

Reverse Blue Screen

This process was developed in response to a requirement to be able to matte objects incorporating highly reflective surfaces, such as glossy paint even blue paint or specular metallic materials, as well as details such as mesh, thin wires, and the like.

The corrected dome port permits the lenses to function with their true focal lengths. The dome radius is critical and its center must be on the nodal point of the lens to function correctly, if not diopters will be...

ZAxis Displacement for Closeups

When it is essential to make a rather extreme closeup of a single object or person, it can be done without a halo by observing a special rule. If the single foreground object extends outward in all directions from the center of the camera-lens axis, it then becomes possible to move the camera forward by several inches, placing it well within the shadow cone of the projector. This action would normally produce a severe shadow on the inside edge of all off-center objects. But the single object or...

Equipment and Filming Technique

In the Arctic or on mountain climbing expeditions, as the altitude and the subsequent cold increase, breathing becomes difficult, and it involves a great effort to work normally. Reactions are slow. Therefore, everything pertaining to the use of the camera should be made as simple as possible. Exposure estimates may be poor when the faculties are dulled, so exposure and other data should be printed on a card and fastened to the camera or its cover in plain view. Certain general cold-weather...

Composing mm for blowup to mm

The aspect ratio of a picture frame is the relationship between its width and height. The ratio of the standard 16mm and 35mm frame is 1.33 1. Reducing the height of the picture while maintaining the width will increase its aspect ratio. This is done in 35mm projection by using a mask to crop equally the top and bottom of the picture frame. 35mm prints are projected at a 1.85 1 aspect ratio in the United States and at 1.66 1 in Europe. On TV, the picture is viewed at a 1.33 1 aspect ratio. This...

Extension of Prime Lens

As the prime lens is moved forward, less light is transmitted because the effective T-stop is progressively diminished by its distance from the film. At a subject-to-lens distance of about 10 focal lengths field width of 8 for 35mm, or 4 for 16mm this begins to become noticeable. The table shows the amount of illumination increase required to maintain full exposure in terms of image scale factor. By convention, most camera lens distance scales are calibrated at a subject distance measured from...

Film Stock

Improvements in film stocks are now occurring with such rapidity as to preclude the prior practice of providing comparative data in this manual. Instead, guidelines for use in selecting and testing appropriate stocks for composite photography will be discussed. The importance of color difference matting in composite photography has now been sufficiently well established that all manufacturers have made efforts to achieve the requisite chromatic discretion in their product. Recent years have...

Photographing Miniatures

The recent increase in the use of miniatures in motion pictures means that live-action cinematographers may now be called upon to photograph miniatures, an area usually handled by specialists. Today's pinpoint-sharp lenses, very fine-grain color negatives, and crystal-clear 70mm release prints can reveal flaws, and the solutions require the utmost attention to detail by every member of the effects team. The cinematographer should talk to the director, the live-action director of photography,...

Diopter Lenses

By definition, diopter is the measure of the power of the lens expressed as the reciprocal of the focal length in meters 1000 divided by the focal length of the lens in millimeters . The term is commonly used by cinematographers to refer to supplementary lenses used in close-up photography. The lenses are generally of a weak meniscus form and are marked with the number indicating the diopter power V2, 1, 2, etc. When a prime lens is set at scale focus infinity, and a diopter lens is mounted in...

Aerial Image Zoom for Oxberry Animation Stand

Although it is not possible to zoom the camera while using an aerial image on an animation stand, it is possible to zoom the aerial image itself. The area taken by the camera lens will still be the same 10 V2 field of the table top condenser, but the aerial image generated will be a zoomed version of the frame in the aerial-image projector. To generate a zoom aerial image, the standard aerial-image projector is replaced by an aerial-image configuration very similar to that of an optical...

Infrared Cinematography

Because cinematography by infrared light has had limited pictorial use, this will be a brief review. For more information, refer to Kodak publications number N-17 Kodak Infrared Films and M-28 Applied Infrared Photography. Infrared for photographic purposes is defined as that part of the spectrum, approximately 700 to 900 nanometers, which is beyond the visible red, but not as far as would be sensed by humans as heat. All infrared films are sensitive to heat and should be kept refrigerated...

Optical Flat Projection

Single-strip 35mm 3-D films can easily be converted for standard flat projection by making an optical internegative for non-3-D prints. For converting 35mm wide screen, the usual method is to optically reprint one of the two stereo images anamorphically, as was done with the Techniscope process, or crop slightly for 1.85 or 1.66 flat format. For single-camera 70 side-by-side, simply convert one side to 70mm blow up or 35mm 1.85 to 1.66 reduction. For dual-camera systems, no change in the print...

Tropical Cinematography

Heat and humidity are two basic sources of potential difficulty when using or storing photographic goods in wet tropical climates. Heat alone is not the worst factor, though it may necessitate special equipment care and processing techniques and may shorten the life of incorrectly stored light-sensitive materials. High humidity is by far the greater problem because it can cause serious trouble at temperatures only slightly above normal, and these troubles are greatly increased by high...

Dynalens

An optical stabilizing device mounted on the camera optical axis for compensating for image motion due to vibration of the camera. A pair of gyro sensors detect rapid motion and drive two gimbal-mounted glass plates, between which is a liquid-filled cell. One plate moves around a vertical axis and the other around a horizontal axis in a manner which deviates the light path opposite to the vibratory movement, causing the image to stay still relative to the image receptor film or video .
