Graflex Photography is built around three simple elements:
1. A reflex viewing-focusing optical system that shows on a ground-glass an exact, erect image of the scene to be photographed, without parallax and with the same depth of field as the image on the negative; 2. a multiple-speed focal-plane shutter giving a wide range of exposures up to 1/1000 with efficiency and reliability; and a 3. wide selection of sensitized materials through availability of various types of holders, and a quick, simple, positive means of attaching them to the camera.
The first two elements are interlocked to make operation rapid and simple; the third gives an unlimited choice of emulsions to suit all conditions and types of work. 1. Reflex focusing is illustrated in Figure 1. Light enters the camera through the lens 5 and is reflected upward by the mirror 3 to the ground-glass screen 2; visibility of the image is improved by the light-excluding focusing-hood 1. The lens is focused by focusing control 4. Since the focusing screen and thefilm are equidistant from the lens, sharpness of the image on the ground glass indicates the sharpness of the negative. The mirror automatically lifts away just before exposure, so that light from the lens passes directly to the film to form the image.
2. The focal-plane shutter is a curtain (Figure 2) of special cloth containing five slits of different widths. It is carried on an upper roller and winds down across the film and onto a lower roller when released by movement of the mirror. (Its action may be observed with the film holder removed from the back of the camera.) The time of exposure is governed by two variables:
a. the width of the slit (or curtain aperture), and b. the speed of the curtain (controlled by tension of the lower roller) .
The shutter-speed plate (Figure 6, 6a, 6b) shows the various exposures resulting from different combinations of slit and tension.
Directions for the shutter controls will be found on pages 9,10,11,12 and 13.
3. Sensitized materials to receive the image are carried in a suitable holder (Figure 8) behind the curtain. Several types of accessories are available for this purpose: sheet film holders. plate holders, film pack adapters and sheet film magazines for all sizes of the Graflex; and for certain sizes only there are plate magazines and roll holders. Instructions for using the last three types of accessories are supplied with them.
A fine camera is primarily an instrument rather than a machine, and the reputation which Graflex products have won for sturdiness and continued functioning under adverse conditions should in no sense be an invitation to abuse them. To insure the long and trouble-free life of which your camera is capable, study and follow these directions as you handle it for the first time. Above all, do not twist any knobs or push any buttons on this camera until you know what this pamphlet tells about them. Do not lend your camera to anyone not familiar with it without instructing him in how to use it. If you lose this book, write us for another.
Since the manner of operating all Graflex cameras is the same in all important details, this manual applies equally well to all current and most older models. Minor points of variation between the different models will be clearly emphasized and explained. These differences relate principally to 1. opening and closing the camera, 2. interchanging lenses, and 3. focusing controls.
The National Graflex, RB Series C, and the 5 x 7 RB Home Portrait Graflex and some of the earlier folding cameras, are covered by their own special manuals.
Series B * R.B. Series B * R.B. Series D * R.B. Super D * R.B. Tele * R.B. Auto (Stationary Back) * Auto Jr. * R.B. Jr.
The top is first opened (Figure 3) by releasing the spring catch L at the upper front of the camera, pulling the top up and hack until the focusing hood is fully extended and straightening the two side braces until they lock in position.
Then open the front of the camera by turning the knurled focusing control S forward (clockwise); this moves the lens carrier and lens forward and automatically releases the front door so that it snaps up. The opened door of the R.B. Super D and Series D serves well as a lens-shade by virtue of the side flaps.
R.B. Auto Graflex
Open the top as directed above. This model has an extra-long bed, which accommodates the additional bellows extension and also serves as the front door. Release it by pressing on the bed-release button under the leather at the top of the extreme front of the camera, and press the bed firmly down until the bed braces snap into position (Figure 10).
There are two focusing controls for the R.B. Auto Graflex (Figure 10, Page 24): one at the lower right front corner of the body, is used for normal work; the other, on the right side of the bed near the front, comes into use when the bellows are given considerable extension--as when focusing at very close range.
Further data on close-up work with the R.B. Auto Graflex will be found on pages 24 and 25, and other specific information on page 9.
Rack the lens all the way back into the camera and close the front door or bed, making sure that it snaps securely.
To close the top, fold the braces and push the top down, folding the focusing hood carefully back into its original position. Make sure the top is securely held by the snap-catch at the front.
Important: After closing the camera remove all tension from the shutter mechanism by releasing both the aperture and the tension controls to their lowest settings, and raise the mirror by pressing release lever. (See bottom of page 9).
Note: Some large lenses when racked back may not permit the mirror to rise fully. In such an in stance, release the mirror before racking the lens into the camera. This will prevent the mirror from accidentally striking the lens mount.
All Models
Rest the camera in both bands, with the fingers under the corresponding front corners of the body (Figure 4). The thumb of the left hand falls naturally on the release lever, while the right thumb and the forefinger are in position to grasp the focusing knob S. To steady the camera, hold it firmly against the chest. To reset the controls after exposure, tilt the camera to the left so it rests on the left hand and forearm.
