the view and make it impossible to photograph an assembly directly. Frequently, a mirror can be used to your advantage in product photography. A mirror placed at the proper angle and distance shows the opposite side of an object in the reflection, while the camera records the front side directly (fig. 6-13). For example, in photographing an object for damage assessment where the damage is on two or more surfaces, you may find it difficult or impossible to show all the damage in one view without the aid of a mirror. In such cases, the value of a picture may be greatly increased by showing all of the damage in one picture. One instance would be in photographing a cylinder that has been scored or cracked on the inside as well as damaged outside. Both surfaces may be shown in one view by using a mirror. assembly. When it is impossible to position the camera and see the part or object directly, the problem may be solved by using a mirror to reflect the image of an assembled part. undesirable reflections. Often a screen can be set up to block the reflection of unwanted objects. back sides of the object must be evenly balanced; otherwise, the mirrored image appears too dark or too light. Direct the light on the object from the mirror side as well as the camera side. When it is impossible to place a light on the mirror side of the object, use the mirror to reflect the light onto the back side of the object. This requires careful placement of the camera in relation to the light source to avoid strong rays of light from entering the lens. Spotlights are usually more suitable than floodlights as sources of illumination, because a beam of light is easier to control. focusing on a reflected image, the lens must be set for the distance from camera to mirror PLUS the distance from subject to mirror. This naturally requires a much greater depth of field than is ordinarily required. Basic Photography Course |
