A flash cube is a small device commonly used in vintage photography that provides multiple bursts of photographic flash, usually in a cube or rectangular shape. It comprises of four individual flash units, facing in different directions, positioned around a central structure. Each unit contains a single-use flashbulb or flashcube, which emits a bright burst of light when ignited.
Typically, a flash cube is mechanically attached to a camera's hot shoe or alternatively connected through a sync cord. When the camera's shutter is pressed, the flash cube rotates to a new position, activating a different flash unit for each subsequent exposure. This rotation mechanism ensures even lighting coverage around the subject, eliminating the need to reposition the camera or flash manually.
Initially designed for use in film cameras during the 1960s and 1970s, the flash cube provided an efficient and portable solution for amateur photographers seeking reliable artificial lighting. It eliminated the hassle of changing individual flashbulbs after each exposure, offering convenience and ease of use. The flash cube was particularly popular in personal photography settings like family gatherings, parties, or other indoor events.
With the advent of more advanced photographic technology, such as electronic flash units and built-in camera flashes, the flash cube gradually became obsolete. However, it retains its historical significance, representing an iconic symbol of a bygone era in photography.
The word "flash cube" is a compound term consisting of two words.
"Flash" refers to the quick burst of light emitted by a camera flashbulb to illuminate a subject during photography. The term "flash" can be traced back to the early 19th century, derived from the verb "to flash", which means to emit a sudden, bright light.
"Cube", on the other hand, refers to a three-dimensional shape with six equal square sides. The word "cube" comes from the Latin word "cubus" and has been in use in English since the 16th century.
The term "flash cube" specifically emerged in the mid-20th century with the invention of the flashbulb cube, which was a device used in photography. The cube-shaped flashbulb had four individual flashbulbs attached to each side, allowing for multiple bursts of light during photography.
