Photoflash

Photoflash (pronounced foh-tuh-flash)

(1) An alternative name for a flashbulb (mostly archaic), a lamp that emits a brief flash of bright light, used to take photographs in a dark environment.

(2) Of or relating to flash photography (industry use only).

(3) The precise point at which a flashbulb illuminates.

1925–1930: The construct was photo- + flash.  Photo (phot- the prevocalic) was a clipping of photograph and photo was from the combining form φωτω- (phōtō-) of Ancient Greek φῶς (phôs) (light).  The –graph suffix was from the Ancient Greek suffix -γραφω (-graphō), from γράφω (gráphō) (to scratch, to scrape, to graze), probably best known in the derived from -graphy.  Flash was from the Middle English flasshen, a variant of flasken or flaskien (to sprinkle, splash), likely of imitative origin.  In the sense used in photography, it was probably of North Germanic origin and akin to the Swedish dialectal flasa (to burn brightly, blaze) and related to flare.  The Icelandic variation from the Germanic was flasa (to rush, hastily to go).  The word photoflash has a long history as a technical term in photography and the manufacture of photographic equipment but three syllables was just too much for general use and the public used “flash” for just about all purposes, the odd necessity like “flashbulb” embraced to avoid confusion.  Photoflash is a noun; the noun plural is photoflashes.

The industry however needed to be precise so "photoflash" became a frequent modifier, required because of the modular nature of the flash equipment (originally not part of the camera apparatus proper) and even at the tail-end of mass-market analogue photography, not all cameras featured built-in flash-lamps.  A "photoflash" unit was the whole, packaged flash assembly that included the flash-lamp and its housing, the mounting bracket directly attached the unit to the camera's body.  Originally the units were designed to accommodate replacement lamps but in 1960s, single-use units were developed, styled usually as rotating cubes, thus permitting four shots; for industry and consumers it was a cheaper solution and convenient but was an example of the way in the post-war years convenience led to more plastic waste and pollution, the little cubes soon littering the environment rather like the "ring-pulls" that enabled cans of drink to be opened without the need for a tool (the so-called "church key").  Invented in 1959 by US engineer Ermal “Ernie” Fraze (1913-1989), the design was thought a helpful innovation but because they detached completely from the can, millions of the things were soon an environmental blight and, with sharp edges, a safety hazard too.  Under pressure, in the mid 1970s, the industry phased them out, replacing them with the still familiar non-detachable “stay-on tabs”.  The photoflash capacitor is used not only in cameras.  It is an electrolytic capacitor designed specifically to provide a pulse of high-voltage energy for a very short duration and as well as the use in conventional photography, they’re installed also in devices using solid-state laser power supplies including optical readers and some printers but, whatever the hardware to which they’re attached, the purpose is always a brief illumination.  Because of the requirements for feeding a very high current for a precise length of time, the greatest challenge during the development process was to ensure a reliable high discharge pulse without excessive heat generation and thus the physical expansion of components.

Photoflash composition has two meanings: (1) The pyrotechnic material which, when loaded in a suitable casing and ignited, produces a flash of sufficient intensity and duration for photographic purposes and (2) the collections of techniques used by professional photographers when shooting in light conditions where the use of a photoflash is required.  This involves considering things like the available ambient light, distance, angles of surrounding surfaces & their reflective properties and the need for any filtering.  For professionals, photoflash devices (known variously as flashes, speed-lights, studio strobes and a number of other terms) are adjustable to an extent those used on consumer lever cameras typically are not, the relevant metric a product of the relationship between the distance between the subject & light source and what is called the focal length (dictated essentially by lens aperture).

An example of a basic design that was "right" from day one, the RAF's photoflash was manufactured throughout World War II (1939-1945) with the only fundamental change the use of narrower fins on the Mk II version, the larger units found to be prone to inducing "lateral drift" in high winds.  The cardboard tubular body was closed at the tail by a dome while the nose was sealed by a diaphragm with a bush, into which was inserted the fuse.  A defined measure of flash composition was loaded between the front and the rear diaphragm with a central tube extending between each, filled with gunpowder.  As soon as a fused flashbomb was released from an aircraft, the fuse was operative, triggering the gunpowder at the desired height which burst the body of the photographic flash, simultaneously igniting the flash composition.

Photoflash composition was of critical importance in the photoflash cartridges used in photoflash bombs which were specialized forms of ordnance perfected during the early years of World War II.  Dropped from aircraft passing over enemy territory, they were fitted with a photoflash cartridge timed to detonate at a height chosen to optimize the spread of light over the area of interest.  The development of the devices had been encouraged by research confirmed only a small fraction of the bombs dropped by the RAF were coming within miles of hitting the target zone, despite the claims of aircrew.  For many reasons, the inaccuracy was understandable given that night bombing over distance was a new aspect of war, carried out by inexperienced aircrew in the cold and dark of night, while under fire from night-fighters and ground-based guns, all while trying to locate blacked-out targets.  In the early days, navigators could rely on little more than maps, charts, mathematics and the visual recognition of physical ground-features, the latter obviously marginal at night when cities were under restrictions making visible artifical light a rare sight.

There would later be electronic innovations such as devices designed to let bombardiers “see through” cloud but the photoflash bomb (always in the RAF clipped to “flashbomb”) was a relatively simple approach that  scaled-up existing technology, the things essentially big versions of the flashbulbs used on cameras.  Given their size, they were capable for short periods of producing intense light of sufficient dispersal and luminosity to permit either a pilot accurately to position his craft for a bombing run or for surveillance aircraft to take aerial reconnaissance photos at a safe height.  Of great utility at the time, flashbombs are no longer part of the military inventory because of improvements in night-vision optics, radar and satellite imagery.  Without them, the RAF's bombing campaign would have been much less effective although, as it was, not until late 1943 was the Anglo-American effort operating at the scale required for the offensive to be strategically significant and until the last weeks of the conflict, the losses suffered by both the RAF and USAAF (US Army Air Force) were shockingly high.

The pathfinder concept was a lead aircraft that would identify a target and then drop flares indicating a target-path & target-force for the main force.  Fast, robust and built quickly and economically by virtue of the plywood frame, the twin-engined Mosquito was ideal for the role.  One of the most versatile airframes of the war, it took the Germans some time to develop a fighter than could match its pace and De Havilland responded to that threat with even faster versions.  Remarkably, the Mosquito (which first flew in 1940) remained in production until 1950, radar-equipped versions serving with the RAF until 1952, the durable platform at the time the UK's only all-weather nightfighter until versions of the De Havilland Vampire (1943-1961) and Gloster Meteor (1643-1955) became available.  Few probably think of the Mosquito as as Cold War aircraft but such was the UK's technology deficit at the time there was no alternative.  As well as the use in the pathfinder role, PR (photo-reconnaissance) versions of the Mosquito flew night-time missions over Europe, Burma and the South Pacific, all using the flashbombs with a the same basic but effective engineering and method of construction that would for centuries have been familiar to fireworks makers: A cardboard tube, capped on both ends with metal stoppers and filled a flash powder charge, the fuse set to trigger after a certain time (length of the fuse determining detonation height).  Being a camera’s flashbulb writ large, the flash lasted only around 200 milliseconds but this was ideal for aerial photography and could be enough for a pilot’s visual orientation although flashbombs often were dropped in staggered clusters, providing an extended duration of enhanced visibility.

Ms Loren's sideways glance, one of the most famous in Hollywood's long history of such looks, variously has been interpreted as “sceptical”, “disapproving” and “envious”, the latter view perhaps most held by men.  Ms Loren herself explained things as "genuine concern" the pink satin gown might not prove equal to the occasion; on the night, there were several photographers covering the event and images shot from other angles illustrate why that concern was reasonable.  There has never been any doubt Ms Mansfield's "wardrobe malfunction" was "engineered and rehearsed", a trick suitably qualified women perfected in the age of the paparazzi.  In her pomp a significant figure in popular culture and a celebrity at a time they were less numerous and not as transitory, Ms Mansfield was a model & actress and what would later come to be known as a “multi-media personality”.  When young, she won a number of sponsored beauty contests including being crowned “Miss Magnesium Lamp”, “Miss Fire Prevention Week” and “Miss Photoflash” but it’s reported she drew the line at becoming “Miss Roquefort Cheese” on the grounds it “just didn’t sound right”, something on which she seems not to have expanded.  Reputedly, the chance to be “Miss Prime Rib” also was declined and while that sounds a missed opportunity, she was sentimental about animals.
