Figure 4-25.–Sliding front and rear of view camera. Figure 4-26.–Using sliding controls to center image. Figure 4-27.–Using rising and falling front-to-center image vertically. 3. Slide or shift. Both the front and rear standard shift or slide from side to side (fig. 4-25). The sliding front or sliding rear is used to center the image on the ground glass horizontally (fig. 4-26). The sliding front or sliding rear is used when the image is not centered after the camera is set on a tripod. These controls are used instead of moving the tripod. When the tripod is moved, the horizontal corrections are altered and  must  be  reevaluated. 4. Rising and falling front. The rising and falling front is used to center the image vertically on the ground glass (fig. 4-27). This control raises and lowers the lens board. This prevents you from tilting the entire camera and nullifying the distortion corrections made on the vertical  plane. VIEW CAMERA OPERATION The view camera is easy to use, but this requires some  thought  and  patience  to  use  it  properly.  The  more the camera is used, the more comfortable you will be with it. The following progressive steps are used when using the view camera: 1.   Set up and level your tripod. 2. Set the camera controls to the neutral position. The neutral position is the starting point for photographs taken with a view camera. In the neutral position, all controls are lined up and no corrective movements are set. Adjust the front and the rear standards so they can be moved to focus the image. 3. Open the shutter and set the diaphragm at maximum   aperture. 4. Roughly compose the image on the ground glass. 5. Focus the image. 6. Check the image size and subject coverage. When   required,    change   lens   focal   length, camera-to-subject distance, or both. Small image size adjustments may be made by sliding the monorail forward or backward. 7. Correct distortion by using the swing and tilt controls. The image must be refocused after each control is moved. 8. Recenter the image horizontally by using the sliding front or the sliding rear. The image is recentered vertically  by  using  the  rising  and  falling  front. 9.   Refocus the image. To obtain greater depth of field, swing or tilt the lens board so it is parallel with the film  plane. 10.  Refocus. 11.   Determine  your  exposure.  When  necessary,  be sure  to  take  the  bellows  extension  into  account. 12.   Stop  down  the  diaphragm  and  check  the  depth of field. 13.   Check the circle of illumination. You will loose the  circle  of  illumination  when  extreme  camera 4-29
