    • A camera for taking pictures, comprises a viewfinder masking device having three different format mask configurations; a manual picture-format selector having three different format selection settings which correspond respectively to the three different format mask configurations in order to select any one of the three different format mask configurations; and a default reset for returning the selector to a predetermined one of the three different format selection settings and returning the viewfinder masking device to a corresponding one of the three different format mask configurations, when the selector is in any one of the selection settings that is not the predetermined one, after a picture is taken and before another picture is taken.

    • A photographic camera (10) includes a film supply chamber (14); a film takeup chamber (16) and a film exposure gate (18) positioned between the chambers. The gate defines a maximum exposed image width (W) in a direction of film travel between the chambers and a maximum exposed image height (H) in a direction transverse to the direction of film travel. A plurality of mask members (24, 26) extend transverse to the direction of travel, each mask member being configured for masking only a portion of the maximum exposed image width. There is no mask in the camera configured for masking a portion of the maximum exposed image height. A mechanism (88-94) moves the mask members toward or away from a center of the exposure gate to reduce or increase only a final exposed image width (W.sub.e), without masking the maximum exposed image height. As a result, the final width of the exposed image indicates a required enlargement of exposed image to produce a pseudo telephoto print. A viewfinder (22) may have mask members (28-34) which move synchronously with the mask members at the exposure gate; or with a zoom lens element (110-114) which also moves synchronously with the mask members at the exposure gate.
    • 照相机(10)包括胶片供应室(14); 薄膜卷取室(16)和位于各室之间的胶片曝光门(18)。 所述门限定了在室之间的膜行进方向上的最大曝光图像宽度(W)和在垂直于膜行进方向的方向上的最大曝光图像高度(H)。 多个掩模构件(24,26)横向于行进方向延伸,每个掩模构件被配置为仅掩蔽最大曝光图像宽度的一部分。 相机中没有配置遮罩最大曝光图像高度的一部分的遮罩。 机构(88-94)使掩模构件朝向或远离曝光门的中心移动,以减少或仅增加最终的曝光图像宽度(We),而不掩盖最大曝光图像高度。 结果,曝光图像的最终宽度表示曝光图像的所需放大以产生伪长焦打印。 取景器(22)可以具有在曝光门处与掩模构件同步移动的掩模构件(28-34) 或与在曝光门处与掩模构件同步移动的变焦透镜元件(110-114)。
