    • An apparatus for macrophotograph comprising a camera, an electronic flash unit having a variable power output, a bracket for connecting the electronic flash unit to the camera in such manner that an angle formed between an axis passing through a lens of the camera and an axis passing through the flash unit is adjustable, and a calculator device for calculating an appropriate power setting for the flash unit. The calculator device has a first set of indicia for determining the reproduction ratio between the size of the object being photographed and the size of an image of the object on film, a first set of cooperating scales for adjusting actual film sensitivity to obtain an effective film sensitivity based on the reproduction ratio, a second set of cooperating scales correlating the effective film sensitivity with the f-stop or lens opening, and a third set of cooperating scales correlating the flash to subject distance with different power outputs of the flash unit. The second and third sets of scales are positioned on the calculator device in such manner that variation of the relationship between the scales of one of the sets automatically varies the relationship between the scales of the other of the sets. The calculator device is effective to determine appropriate power settings for both macrophotography and fill flash at close distances.
    • 一种用于包括相机,具有可变功率输出的电子闪光灯单元的用于广角照相机的设备,用于将电子闪光单元连接到照相机的支架,使得在通过照相机的透镜的轴线和通过照相机的轴线之间形成的角度 通过闪光灯单元是可调节的,以及用于计算闪光灯单元的适当功率设置的计算器装置。 计算器装置具有第一组标记,用于确定被拍摄物体的大小与胶片上的物体的图像的大小之间的再现比例,用于调整实际胶片感光度以获得有效胶片的第一组合作标尺 基于再现比率的灵敏度,将有效胶片感光度与f停止或透镜开口相关联的第二组协作尺度以及将闪光灯与被摄体距离相关联的第三组协作尺度与闪光灯单元的不同功率输出相关联。 第二和第三组刻度以这样的方式定位在计算器设备上,使得其中一个组的尺度之间的关系的变化自动地改变另一组的尺度之间的关系。 计算器设备有效地确定近距离进行的摄影和填充闪光灯的适当功率设置。

    • An electronic flash unit assembly having an electronic flash module separate from a power and control module. An assembly of articulated flash arms supports the flash module spaced from a camera. A power cord interconnects the power and control module with the flash module so that power is transmitted to the electronic flash tube from the power and control module when the power and control module is triggered. Preferably, a power cord connects the power and control module to the camera so that triggering of the module occurs upon movement of a shutter release member of the camera. The power and control module is connected to the tripod socket of the camera and supports the flash arm assembly. Alternatively, a mounting plate is connected to the tripod socket of the camera and supports the flash arm assembly, with the power and control module being in a separate unit.
    • 一种具有与电源和控制模块分离的电子闪光模块的电子闪光灯组件。 铰接式闪光臂的组件支撑与相机间隔开的闪光模组。 电源线将电源和控制模块与闪存模块相互连接,以便在触发电源和控制模块时,从电源和控制模块将电源传输到电子闪光灯管。 优选地,电源线将电源和控制模块连接到相机,使得在相机的快门释放构件移动时发生模块的触发。 电源和控制模块连接到相机的三脚架插座,并支持闪光臂组件。 或者,安装板连接到照相机的三脚架插座,并且支撑闪光臂组件,电源和控制模块位于单独的单元中。
