用于保持照相机和闪光灯单元以使它们彼此分开的装置，包括具有用于保持闪光灯单元的上部和用于保持照相机的下部的框架，并且在下部附近具有一对横向隔开的手柄。手柄的方向是这样的，所以他们可以舒适地保持在略低于眼睛的水平，上臂向下延伸并支撑在身体上，前臂向上延伸。其中一个手柄形成一个位于相机下方的掌垫，这样右手就可以在右手握住掌垫的同时，拇指和中指或食指放在相机镜头上转动相机镜头进行对焦，或者放在光圈上改变镜头的开口。另一个手柄接受左手，呈杆状，与垂直方向成角度，这样就可以握住左手，而不会让摄影师的手在手腕抽筋。
Apparatus for holding a camera and flash unit so they are separated from one another, including a frame having an upper portion for holding the flash unit and a lower portion for holding the camera, and having a pair of laterally spaced handles near the lower portion. The handles are oriented so they can be held comfortably at slightly below eye level with the upper arms extending down and braced against the body and the forearms extending upwardly. One of the handles forms a palm pad lying under the camera so that the right hand can hold the pad in the palm while the thumb and middle or forefinger rest on the camera lens to turn it for focusing, or rest on the aperture ring for changing the lens opening. The other handle, which receives the left hand, is in the form of a bar which is angled from the vertical so it can be held without cramping the photographer's hand at the wrist.
