A short introduction to the film slide

/ spqr / Leave a comment

A “slide” in the more common use of the word refers to a translucent positive image which is held inside a cardboard sleeve, or plastic frame (or mount). A positive image is created using reversal film, whereas negative film produces an inverted or reversed image (which in turn is used to make a paper photo). When a slide is held up to the light, it is possible to see the scene as it was shot rather than the “negative” of the scene. Slides are typically viewed using a slide projector which projects the image against a white screen. Without the mount, the film would not be able to “slide” from one image to another when inside the magazine of a projector.

The classic Kodachrome slide

The slide is not a modern phenomena. The earliest was likely the Lantern slide, also known as the “magic lantern”. It was an early type of image projector which appeared in the 17th century which projected glass slides onto various surfaces. With the advent of photographic processes in the mid-19th century, magic lantern slides were black-and-white positive images, created with the wet collodion or a dry gelatine process on glass. Slide shows became a popular pastime in the Victorian period, but they were not the same as modern film slides.

Examples of colour slides

It 1826 Nicéphore Niépce invented the first form of negative photography, but it would take nearly a century before its use in flexible celluloid film became a reality. The earliest commercially successful reversal process came into being in 1907 with the Lumière Autochrome. It was an additive screen-plate method using a panchromatic emulsion on a thin glass plate coated with a layer of dyed potato starch grains. It was Leopold Godowsky Jr., and Leopold Mannes working with Kodak Research Laboratories who in April 1935 produced the first commercially successful reversal film – Kodachrome (first as a 16mm movie film, and in May 1936 as 8mm, 135 and 828 film formats). Based on the subtractive method, the Kodachrome films contained no colour dye couplers, these were added during processing. In 1936 Agfa introduced Agfa Neu, which had the dye couplers integrated into the emulsion, making processing somewhat easier than Kodachrome.

There are different types of reversal film, based on the type of processing. The first, which includes films like Kodachrome, uses the K-14 process. Kodachrome is essentially a B&W stock film, with the colour added during the 14-step development process. That means it has no integrated colour couplers. Kodachrome was an incredible film from the perspective of the richness and vibrancy of the colours it produced – from muted greens and blues to bold reds and yellows. However developing Kodachrome was both complex and expensive, which would eventually see the rise of films like Ektachrome, which used the E-6 development process (a 6-step process). Films like Ektachome have different emulsion layers, each of which is sensitive to a different colour of light. There are also chemicals called dye couplers present in the film. After slide film is developed, the image that results from the interaction of the emulsion with the developer is positive.

Common slide mount sizes

Many companies made reversal films, typically acknowledged through the use of the “chrome” synonym – e.g. Agfachrome (Agfa), Fujichrome (Fuji), Ektachrome (Kodak), Scotchchrome (3M, after buying Italian filmmaker Ferrania), Ilfochrome (Ilford), Peruchrome (Perutz), and Anscochrome (the US arm of Agfa). The initial Kodachrome had a very slow speed (10 ASA), this was replaced in 1961 by Kodachrome II (1961) which produced sharper images, and had a faster speed (25 ASA). In 1962 Kodak introduced Kodachrome X (ASA 64). Kodak’s other transparency film was Ektachrome, which was much faster than Kodachrome. In 1959 High Speed Ektachrome was introduced, providing a ASA 160 colour film (by 1968 this had been pushed to ASA 400).

What about the “slide” side of things? A patent for a “Transparency Mount” was submitted by Henry C. Staehle of Eastman Kodak in October 1938, and received it in December 1939. Its was described as “a pair of overlapping flaps formed from a single strip of sheet material such, for example, as paper.”. Early slide mounts were mostly made of cardboard, but as plastic became more common, various designs appeared. Most cardboard mounts were either hinged on one side or two separate pieces, glued together after the emulsion was sandwiched between the two sides of the frame. There were also systems for the DIYer, where the emulsion could simply be inserted to the slide frame. Plastic frames were either welded together or designed in an adjustable format, i.e. the film frame could be inserted and removed. The exterior dimension of most common slide formats is 2 inches by 2 inches. There were many different sizes of slides, all on a standard 2″×2″ mount, to encompass the myriad of differing films formats during the period. Slides are usually colour – interestingly, black-and-white reversal film does exist but is relatively uncommon.

Some different types of slide frames

Slides were popular from the 1960’s probably up until the early 1990’s. It was an easy way to get a high-quality projected image in a pre-digital era. Slides were a popular medium for tourists to take pictures with, and then beguile visitors with a carousel of slides depicting tales of their travels. Slide film is still available today, all of which uses the E-6 process. E-6 slide film is a lot less forgiving as it has a lower ISO value but produces vivid colour with evidence of finer grain. Modern slide films include Kodak Ektachrome 100, Fujifilm Velvia 50, and Fujifilm Fujichrome Provia 100.

Now that’s a camera!

An 8×10 still camera operated by photographer Neal Harburger used to capture stills on Paramount westerns c.1930s. The camera was a Minex, designed by A. Adams & Co. of London. The camera was 18 inches high, 30 inches long (with the bellows extended) and weighed 34 pounds. From the literature it looks to be the “Tropical” model made of brass, teak, and Russian leather bellows.

The kit of the mid-century photojournalist

/ spqr / Leave a comment

Photojournalism had its origins in the photography of war. Photojournalists are photographers who take pictures that illustrate or tell a story. The first photograph used as an “illustration of a newspaper report”, was a daguerreotype taken by Charles-François Thibault in Paris during the bloody June Days uprising in 1848. Two images were taken at Rue du Faubourg-du-Temple : the scene depicts a barricade on a empty street, at 7.30am on June 25th. On July 8th, the newspaper L’Illustration reproduced the images as woodcuts. Photographic coverage of the Crimean War (1853-1856), and the American Civil War in the 1860s required cumbersome cameras taking long exposures on plates – shots were taken before or after battles because combat coverage was impossible. WW1 brought medium format cameras with glass-plate negatives (these were used by “official” photographers, soldiers used the Vest Pocket Kodak).

The Golden Age of photojournalism was considered to be the period of the 1930s through the 1950s, largely due to the introduction of the Leica 35mm camera in 1925. But what sort of kit did the average photojournalist (not including army combat photographers) use in the mid-century period? Being a photojournalist was a demanding occupation. Consider the words of Boris Spremo (1935-2017): “

“I have walked through the wreckage’s of plane crashes and smashed cars . . . knelt beside dying people in Central Africa . . . faced bullets . . . run from tear gas bombs, been chased by angry mobs . . . ridden in a dug out canoe in the sweltering jungles of South America and on dog sleds at 50°C below zero in the Canadian far north . . . ”

Spremo, Boris. Boris Spremo: Twenty Years of Photojournalism. Toronto: McClelland, 1983.

So it is imaginable that a typical photojournalist would want to carry as little gear as possible. In the 1930s, while 35mm had followers, many photojournalists still used large format press cameras. For example Charles Kerlee (1907-1981) in his 1939 book “Pictures With a Purpose – How They Are Made” describes using a 4×5 series D Graflex with a 8¼” Steinheil Cassar lens, or a 40cm Tele-Tessar lens (400mm=135mm, 8¼”=65mm in 35mm equivalency).

Robert Capa (1913-1954), who it is rumoured photojournalist, L.B. “Jeff” Jefferies is based on in the movie “Rear Window” was an icon of photojournalism, covering the Spanish Civil War and WW2. Capa is known for using a Leica at the beginning of his career, including for one of his most famous works, Falling Soldier taken during the Spanish Civil War. But by his coverage of the Chinese resistance to the Japanese invasion in the late 1930s, he had switched to the Contax II series of cameras. In 1944 as he followed allied troops onto the beaches at Normandy (the “Easy Red” sector of Omaha Beach), he carried two Contax cameras. His preference was for 50mm lenses, with a certain liking of the Zeiss 50mm Sonnar f/1.5. When he left on that ill-fated assignment to Indochina in 1954 he carried a Nikon S to complement his Contax.

A Contax II

Horace Bristol (1908-1997) was another American photographer who was best known for his work in Life. After WW2, Bristol settled in Japan, publishing “Tokyo on a five day pass with candid camera” in 1951. Although photographing for a photo-book he describes in detail the type of gear used through the process. It seems Bristol largely used 35mm cameras, typically still known as the “candid camera”. He states that while a telephoto and wide-angle are needed, the workhorse is the 50mm, it will “do almost anything any lens will do”. Photographing for the book, Bristol used an array of cameras, but typically carried a Canon III and Leica IIIc for candid work (likely what we would today term street photography). As to lenses, Bristol carried the following array: Serenar 135mm f/4, Serenar 85mm f/2, Nikkor 50mm f/1.4, Serenar 50mm f/1.8, Serenar 35mm f/3.2 and a Serenar 38mm f/3.5. Of course this sort of photography allowed for greater flexibility (Serenar = Canon).

Photojournalists also typically did not carry the full gamut of lenses. As suggested by Bristol:

“Don’t, however, be lead into the error of thinking that the answer to good pictures is to be found in a complete set of matched lenses. just the opposite is true, for there is a very definite correlation between the number of lenses the average photographer carries, and the worth-while pictures he produces. Unfortunately, this varies in inverse order; in other words, the more equipment to worry about, the fewer pictures of merit!”

Horace Bristol, Tokyo on a five day pass with candid camera (1951)

Many photographers adopted “candid cameras” because they were compact and convenient. W. Eugene Smith (1918-1978) supposedly left Newsweek in 1938 because they wanted him to work with a larger format, but he preferred his Leica. After that he secured a job at Life. Over his career he used many different 35mm cameras, Leica, Contax, Pentax, Nikon. His preference was for 21mm, 28mm, 35mm, 85mm and 135mm lenses. Yevgeny Khaldei (1917-1997), the Ukranian photographer who captured one of the most iconic WW2 photographs of a Soviet soldier raising a flag over the Reichstag in Berlin, used a Leica III throughout his career.

In the end, it is likely that 35mm cameras took over from larger format because they were practical. Practical and efficient, in the fast-paced world that photojournalism was becoming.

Rear Window – the 400mm lens

/ spqr / Leave a comment

In a previous article, I discussed the Exakta VX camera used in Alfred Hitchcock’s “Rear Window”, suggesting that photojournalists of the period likely didn’t use super-telephoto lenses all that often (or at all). My view on this is based largely on articles I have read in magazines like Popular Photography during the 1950s.

The telephoto lens used by Jefferies in the movie is the Kilfitt Fern-Kilar f/5.6 400mm lens. The lens fits into the category of super-telephoto lenses with focal lengths in the range of 300-600mm. A number of manufacturers produced these lenses, although in all likelihood they had a narrow market. One of the earliest ads for Kilfitt lenses in Popular Photography appears in 1953, advertising their KILAR lenses for “medium and long tele shots” – it includes the 300mm and 400mm lenses. A review of the ads section of Popular Photography in 1954 reveals that the Kilfitt 400mm was being sold alongside the f/5.5 Hugo Meyer-Goerlitz Tele-Megor (which was the lens promoted by Exakta as well), and the Astro f/5.

The Kilfitt-Fern-Kilar 400mm f/5.6

Literature from Heinz Kilfitt Optische Fabrik suggests the lens could be used for “nature and expedition photography“, and also for “special press and feature assignments“. It is then likely that these long lenses were used in situations where a large kit could be carried. Some may argue that Jeff used the lens for sports photography, but that is unlikely, as many photojournalists tended to focus their careers on a particular genre of photography. For example Robert Capa, upon who Jefferies character is loosely based, worked predominantly in war zones: the Spanish Civil War, WWII, Palestine, and the war in Indochina (where he was killed by a landmine). In 1951 Bruce Downes wrote an article in Popular Photography, describing David Douglas Duncan’s photo coverage of the Korean War [2]. He photographed the carnage of war using two Leica IIIc’s, “practical combat cameras” that were “…light, compact and could stand a beating.”. From the perspective of lenses, he used Nikkor lenses: a 50mm f/1.5, a 85mm f/2 and a 135mm f/3.5. No large telephoto lenses in sight.

A steady telescope

In addition, even sports-photojournalists did not generally use long-tele lenses. Jesse Alexander (1929-2021), a motor-sports photographer, reportedly did not use long telephotos lenses. At the start of his career in early 1950s (his first photographic assignment was the 1953 La Carrera road race in Mexico), he used a Leica with 35mm and 135mm lenses, and a Rolleiflex for close-ups and portraits. I would suggest that the 400mm lens was either something Jefferies used occasionally, perhaps for some hobby photography, or merely something added to meet the needs of film. The only real evidence of Jefferies taking sports shots is the motor racing shot that ended up with Jefferies stuck in his apartment with a broken leg. The camera used there was a large format camera (most likely a Graflex), as evidenced by the photo hanging on the wall, taken in the middle of the racetrack.

Identifying the lens

The biggest elephant in the room with these telephoto lenses is their weight. The f/5.6 400mm lens weighed 62oz, or 1.76kg in weight. The faster Sport-Fern-Kilar f/4 400mm lens was even heavier, at 3.1kg. These lenses were just too heavy for a photojournalist to carry and use effectively in an active situation, e.g. a war zone. Even in everyday settings, the length of the telephoto would require the use of a tripod, otherwise shake will be greatly exaggerated – “A slight jiggle that would not be noticed if the scene were filmed with a standard lens will look like something shot on a pogo stick when you use a long telephoto lens.” [1]. It might be okay to use as a de facto telescope and prop up on your knee.

The interesting thing about Exakta is that their literature touted the idea of attaching a telephoto lens to a camera and turning it into a telescope – “a telescope that gives you long-range viewing with high magnification“. A 400mm telephoto lens would provide an eight-power photo-telescope.

NB: Sometimes it is speculated that the lens was actually an Astro-Berlin, a German company that made some pretty cool lenses, especially for the super-super telephoto (we’re talking 2000mm, f/10). These telephotos were often seen on Exakta cameras, hence the association.

Japanese Are-Bure-Boke style photography

/ spqr / Leave a comment

Artistic movements don’t arise out of a void. There are many factors which have contributed to the changes in Japanese society. Following World War 2 Japan was occupied by the United States, leading to the introduction of Western popular culture and consumerism, which was aptly termed Americanization. The blend of modernity and tradition was likely to lead to some waves, which was magnified by the turbulent changes occurring in Western society in the late 1960s, e.g. the demonstrations against the Vietnam War. In the late 1960s, Japan’s rapid economic growth began to falter, exposing a fundamental opposition to Japan’s postwar political, economic and cultural structure, which lead to a storm of protests by the likes of students and farmers.

It had a long-term effect on photography, forcing a rethink on how it was perceived. In November 1968 a small magazine called Provoke was published, conceived by art critic Koji Taki (1928-2011) and photographer Takuma Nakahira, with poet Takahiko Okada (1939-1997) and photographer Yutaka Takanashi as dojin members. Daido Moriyama joined a for the second and third issues, bringing with him his early influences of Cartier-Bresson. The subtitle for the magazine was “Provocative Materials for Thought”, and each issue was composed of photographs, essays and poems. The magazine had a lifespan of three issues, the Provoke members disbanding due to a lack of cohesion in their ideals.

The ambitious mission of Provoke to create a new photographic language that could transcend the limitations of the written word was declared with the launch of the magazine’s first issue. The year was 1968 and Japan, like America, was undergoing sweeping changes in its social structure.

Russet Lederman, 2012

The aim of Provoke was to rethink the relationship between word and image, in essence to create a new language. It was to challenge the traditional view of the beauty of photographs, and their function as narrative, pictorial entities. The photographs were fragmented images that rethought the established aesthetic of photography. The photographs they published were an collection of “coarse, blurred and out-of-focus” images, characterized by the phrase Are‑Bure‑Boke (pronounced ah-reh bu-reh bo-keh). It roughly translates to “rough, blurred and out-of-focus”, i.e. grainy (Are), blurry (Bure) and out-of-focus (Boke).

An example of Daido Moriyama’s work.

They tried random triggering, they shot into the light, they prized miss-shots and even no-finder shots (in which no reference is made to the viewfinder). This represented not just a new attitude towards the medium, but a fundamental new outlook toward reality itself. Of course that is not to say that every photograph had the same characteristics, because there are many different ways of taking a picture. The unifying characteristic is the ability to push beyond the static boundaries of traditional photographic aesthetics. Provoke provided an alternative understanding of the post-war years, one that had traditionally been quite Western centric.

Lightning strikes!

/ spqr / Leave a comment

Sometimes we tend to forget how exciting first achievements are. You get a good sense of these if you peruse vintage science journals from the late 1800s, many of which are available online as PDFs. When I was looking for an article from La Nature Revue Des Sciences recently from 1884, I came across another interesting article on the photography of lightning strikes by Gaston Tissandier (Vol.12, No.548., pp.118-119), entitled “Les Éclairs, Reproduits par la Photographie Instantanée“, or “The Flashes reproduced by instant photography”. The images show photographic prints of lightning taken by Mr. Robert Haensel of Reichenberg, Bohemia.

Photographs of lightning, taken on July 6th, 1883 at 10pm, when the sky was very dark

These photographs seem very simple, but are like pieces of artwork. They were acquired using silver-bromide gelatin plates, and activated by the lightning flashes themselves. Now the average duration of a flash of lightning is 0.1-0.2 seconds, so it says a lot about the sensitivity of film at the time. Haensel exposed 10 plates, of which four good negatives were produced. The photographs were reproduced for publication using the photogravure process.

This article was also published in The Popular Science Monthly, as, “Photographing a Streak of Lightning”, Vol. 24 pp.752-754 (April 1884). An earlier article appeared in The Photographic News, on January 4th, 1884 (London).

The first 35mm lens

/ spqr / Leave a comment

With the advent of 35mm film cameras came the need to design 35mm lenses. The first still cameras designed to use 35mm film inevitably used lenses modified from use on motion-picture cameras, or microscopes. This made sense when the 35mm cine-film used the 18×24mm frame format, however these lenses only covered part of a 24×36mm frame. The figure below shows frame coverage of a cine (movie) lens versus a 35mm lens.

Frame coverage of pre-35mm lenses

For instance the Tourist Multiple used a Bausch & Lomb Zeiss 4-element Tessar (50mm f / 3.5 lens), which was used on motion picture cameras.

Leitz, founded in 1869, began as a company focused on the manufacture of microscopes, and other optical instruments. When work began on the Ur-Leica, Barnack and Berek tried a number of lenses. The simplest option was the 5cm f / 3.5 Zeiss Kino-Tessar movie camera lens. The problem is that the lens could not provide a light spot able to cover the 24×36mm frame format, as it was designed for a 18×24mm format. In addition it produced vignetting not suitable for a camera. The lens they ended up using was the 6-element 42mm f / 4.5 Leitz Mikro-Summar, in a classic double-Gauss formula. This lens had a number of shortcomings, including edge blurring, and a lack of contrast.

The Leitz Mikro-Summar (from 1907 catalog)

The design of a new 35mm lens was the responsibility of German physicist and mathematician, Max Berek (1886-1949). The first 35mm lens developed at Leica was a 50mm f/3.5 Anastigmat. Based on the “Cooke Triplet” lens design, it had 5 elements in 3 groups. The lens was later marginally redesigned, still containing 5 elements in 3 groups, and was given the name Elmax (The name is derived from Ernst Leitz and Max Berek.). These lenses were used on the pre-production Leica-0, of which 31 were manufactured from 1920-1925.

The Anastigmat / Elmax lenses

At that time, the calculation of such a lens was still very complex. Light beam paths from points near or away from the optical axis had to be calculated for three wavelengths and seven refractive surfaces, all by hand using logarithmic tables. Leitz was granted patent No. 343086 for the Anastigmat in 1920.

The first lens formula was difficult to build, so Berek changed the design to a triplet with the last element a cemented doublet, i.e., 4 elements in 3 groups. This lens was renamed Elmar, and was subsequently manufactured for decades (1925-1961). The lens was similar to a Tessar, except for the location of the diaphragm. On the Elmar the diaphragm was located between the first and second elements, rather than the rear two elements.

The Elmar lens

The first lenses which appeared were of the fixed type used on the Leica I. From 1930-1959, the Elmar was made in a screw mount, and an M (bayonet) mount from 1954-1961. From 1930-1932 the lenses were matched with one body, after which they became interchangeable (M39 mount). The lens would evolve to have a maximum aperture of f/2.8, and a minimum aperture of f/22. .
