Chapter 2 of "Instruction Manual for RB Super Graflex &c"
Most models of the Graflex are equipped with a revolving back. This is an arrangement permitting the rotation of the film or plate so that its long dimension may be either vertical or horizontal, to make possible vertical or hori zontal format of the picture without turning the camera on its side. To revolve the back, push in on the revolving-back release-button X (Figures 3 and 7) and revolve the extreme back of the camera. Make sure that the catch clicks to hold the back in the proper position; however, if the back is to be revolved only partially, this click will not make itself evident. The back is light-tight and maybe turned with the film holder in place and the slide withdrawn.
The viewing area of the ground glass is shaped somewhat like a cross; when the back is vertical use the rectangular area running fore-and-aft for framing the picture, and when the back Is horizontal use the cross ways portion. The two sets of boundary lines show the limits of the field in each direction, and the center cross4ines help in keeping the camera horizontal and in locating the center of the field.
When it is desirable to observe the Image on a ground glass at the back of the camera, for instance when the camera is placed on a high support, the accessory Graflex Focusing Panel will be required. It may be fitted to the camera by the slide locks which hold the film and plate attachments and are described in the following paragraph. The accessory focusing panel is provided with side shields and a metal door which can be released by pressing down on the small latch directly beneath the door. When raised, this door permits direct ground-glass focusing and composing of the image produced by the lens. Note: Make sure that the focal-plane shutter is set at O, the I-T bar at T, and the mirror raised.
|The various types of film and plate holders attach directly to the back of the camera (without adapters) by means of a slotted slide-lock and a fixed retaining strip (Figure 7). Note that the newer models have slide-locks at both top and bottom. Both must be moved to the left to open and allow fitting or removal of a holder or focusing panel. Moving both slide-locks to the right will lock the attachment in place on the camera. In those models with a single slide-lock at the top, move it to the right to open. Then place one edge of a holder or attachment under the retaining strip and press the other edge firmly against the camera body below the slide-lock; lasily lock the holder in position by moving the slide-lock down as far as it will go.
If you are unable to secure an old film with which to practice in day liqht, use a sheet of new film.
Sheet film holders should be loaded in complete darkness--preferably in a photographic darkroom. Place the holders on a clean work-bench and withdraw the slides, laying them to one side well within reach. As the box of film is opened, note that the sheets are interleaved with black paper.
To find the emulsion side of a piece of sheet film in the dark, note the posiHon of the notches cut into one of its shorter edges. The emulsion side will be facing you when the unnotched short side of the film is nearest you and the notches are in the upper right-hand corner. Always handle the film by its edges and never touch the front (emulsion) surface.
Open the wood flap at the end of the holder, and slide in the film. (Figure 8) - Make sure that the edges are beneath the side rails. The film should be pushed home so that it is under the rail at the other end of the holder. Close the wood flap and replace the slide in the holder, with the raised dots on the outside to show that this side of the holder contains unexposed film. (If the slide does not fit fully into the slot in the end of the flap, the film has not been pushed under the rail at the closed end of the septum). Turn the small brass slide-hook over the end to prevent accidental withdrawal of the slide. When slides are replaced after exposure, have the raised dots inside to show that the film has been exposed.
Plate holders are loaded in much the same way as film holders, except that there are no side rails and the end of the plate is slid in under a projection at the slide-handle end of the holder. The plate is held in place when the wood flap is closed and slide inserted.
Film packs can be loaded in daylight, but strong or direct light should be avoided. When handling a pack always grasp it by only the sides, since the films will be fogged if the protective black paper is depressed. Release both catches and swing the back of the adapter open. Carefully insert the closed end of the film pack under the light-break at the hinge. Be sure that the opening of the pack rests next to the slide of the adapter. With the paper tabs held straight out, close the back. Before making the first exposure, pull the first tab (marked 0) straight out from the pack until a resistance is felt; then bring it around toward the back of the camera and tear it off with a smooth, even motion. After the first exposure tear off tab 1 in the same way, and so on after each exposure until the last tab (12) has been torn off. (Pulling the tabs moves exposed film from the open front of the pack to the back.) After the last tab has been pulled the exposed pack Is somewhat self-protected, and may be removed from the adapter In subdued light to be wrapped In the original paper and box. Handle the film pack only by its edge.
Magazines holding twelve sheets of film in individual septums for exposure and development at will, are covered by a special Instruction manual which accompanies each magazine. A special manual is also available for roll holder attachments which have been supplied for GRAFLEX Cameras.
