PH3  Yvonne  Albritton 302.191 Figure 6-18.–Ruler included in product photograph. CORRECTIVE PHOTOGRAPHY Corrective  photography  is  the  correct  represen- tation of three-dimensional objects on a single plane (the photograph). At one time or another, you have probably taken a picture with the camera tilted up or at an angle to the subject, and you probably learned by experience what the resulting distortion did to an otherwise good picture. Most of the cameras you use on location do not have movements or adjustments for correcting vertical or horizontal distortion that is created when the camera is tilted or used at an angle to the subject. Such inflexible cameras do not allow you to present the subject correctly from any camera position that shows two or three sides of the subject. For the correct presentation of such subjects, camera movements must be used. Many students   of   photography,   as   well   as   many self-acclaimed  pros, are inclined to use cameras lacking the  essential  advantages  (camera  movements  and adjustments) of a view camera. Instead they use their “regular” camera for every assignment even when a view camera is the only correct camera for the job. Refer to chapter 4 to re-familiarize yourself with the view camera.
