70 Fun Facts About Photography

The 'Tank Man' photographs near Tiananmen Square were taken in which year?

1989: on June 5, the day after the crackdown, several photographers shot the scene from balconies of the Beijing Hotel; the man has never been identified.

Which 1839 photographic process produced a direct positive on a silver-plated copper sheet?

The daguerreotype, invented by Louis Daguerre and introduced in 1839, was the first publicly available photographic process, creating a unique, highly detailed image on a silver-plated copper sheet.

Which 1841 Fox Talbot process used paper negatives to make multiple prints?

William Henry Fox Talbot patented the calotype process in 1841, which was significant for its ability to produce a paper negative from which multiple positive prints could be made, laying the groundwork for modern photography.

Who is credited with taking the world's first permanent photograph?

Joseph Nicéphore Niépce created the "View from the Window at Le Gras" around 1826 or 1827 using a process he called heliography. This image on a pewter plate is widely recognized as the first permanent photograph.

What was Frederick Scott Archer's 1851 glass-plate negative process called?

The Wet Collodion Process, devised by Archer in 1848 and published in 1851, gave crisp, reproducible glass negatives and largely displaced the daguerreotype within a decade.

Whose photograph 'V-J Day in Times Square' shows a sailor kissing a stranger on 14 August 1945?

Alfred Eisenstaedt, on assignment for Life with a Leica, said he saw a sailor running down the street grabbing every girl in sight and clicked the moment he kissed the nurse.

Which lens component controls the light reaching the sensor and influences depth of field?

The aperture is an adjustable opening within the lens that regulates the amount of light passing through to the camera's sensor. A wider aperture (smaller f-number) results in more light and a shallower depth of field.

What term is the distance from a lens's optical centre to the sensor at infinity focus?

Focal length determines how much of a scene is captured and how magnified objects appear. Shorter focal lengths provide a wider angle of view, while longer focal lengths offer a narrower view and greater magnification.

What is the common term for the warm, soft light shortly after sunrise or before sunset favored by photographers?

The golden hour, sometimes called the magic hour, is highly prized by photographers for its warm, diffused light, which can enhance colors and create long, soft shadows.

Which composition guideline places key elements along lines dividing an image into nine equal parts?

The Rule of Thirds is a fundamental compositional tool where an image is divided into a 3x3 grid, and important elements are placed along the lines or at their intersections to create visual interest and balance.

What does 'ISO' primarily control in digital photography?

ISO in digital photography determines the sensitivity of the camera's sensor to light. A higher ISO allows for shooting in darker conditions but can introduce more digital noise.

Which type of lens has a fixed focal length, often giving sharper images and wider apertures than zooms?

A prime lens has a fixed focal length, meaning it doesn't zoom. This design often allows for simpler optical construction, leading to sharper images and wider maximum apertures.

Andreas Gursky's 'Rhein II' set a photo auction record in 2011 at roughly what price?

$4.3 million (about $4.34 million at Christie's New York in November 2011). Gursky digitally removed dog walkers and a factory from the scene; Man Ray's 'Le Violon d'Ingres' overtook the record in 2022.

Which photo file format stores unprocessed sensor data, giving the most editing latitude?

Raw files hold unprocessed sensor data at 12-14 bits per channel, so exposure, white balance and colour can be pushed much further than with a rendered 8-bit JPEG. Most raw formats are losslessly compressed rather than truly uncompressed.

What technique captures light trails or silky water by leaving the shutter open for seconds?

Long exposure photography uses a slow shutter speed to capture light over a prolonged period. This technique is commonly used for creating light trails, smoothing water, or capturing stars.

Which photojournalist captured the Great Depression image 'Migrant Mother'?

Dorothea Lange took 'Migrant Mother' in March 1936 at a pea-pickers' camp in Nipomo, California, for the Resettlement Administration; the subject was later identified as Florence Owens Thompson.

The Lumière brothers' Autochrome colour process filtered light through dyed grains of what?

Potato starch: dyed grains formed the colour mosaic. Patented in 1903 and sold from 1907, Autochrome plates were loaded backwards so light passed through the starch layer before hitting the emulsion.

Oskar Barnack's original Leica was the first practical still camera built around which existing stock?

Cinema film: Barnack built the Leica around 35 mm movie stock, running it sideways to get a 24 x 36 mm frame, the '35 mm' format that dominated photography for the rest of the century.

What is the purpose of a 'polarizing filter' in photography?

A polarizing filter is used to reduce glare from non-metallic surfaces like water or glass, deepen blue skies, and enhance color saturation by cutting out polarized light.

What term covers a sensor's ability to capture both bright highlights and dark shadows in one exposure?

Dynamic range refers to the ratio between the lightest and darkest areas of an image that a camera can capture. When the scene's dynamic range exceeds the camera's capability, either highlights or shadows (or both) can lose detail.

The 'Blue Marble', the famous photograph of the fully lit Earth, was taken by the crew of which mission?

Apollo 17 was the first mission positioned to photograph almost the whole daylit face of the Earth, and NASA has never officially said which of the three astronauts pressed the shutter.

The term 'camera obscura', ancestor of the modern camera, is Latin for what?

'Dark chamber': light entering a darkened room through a small hole projects an inverted image of the outside. Ibn al-Haytham studied the effect in the early 11th century, and the eye works the same way.

Who described the gelatin dry plate in 1871, freeing photographers from wet collodion?

Richard Leach Maddox, an English physician, described the gelatin silver bromide dry plate in the British Journal of Photography in 1871; plates could now be made in advance and exposed dry.

What photographic setting determines the duration that the camera's sensor or film is exposed to light?

Shutter Speed sets how long the shutter stays open, from thousandths of a second to minutes; each halving or doubling of that time changes the exposure by one stop.

Edwin Land's first instant camera, the Polaroid Land Camera, went on sale in what year?

1948: the Model 95 Land Camera went on sale at a Boston department store in November 1948, a year after Land demonstrated instant photography; he had founded Polaroid in 1937 to sell polarising plastic.

Under the 'sunny 16' rule, you set the aperture to f/16 and the exposure time to what?

The reciprocal of the ISO: at ISO 100 that means f/16 at 1/100 s, or the nearest 1/125. The rule dates from the era of meterless cameras and works as a sanity check even for digital exposures.

The Brownie box camera, released in 1900 and originally aimed at children, went on sale for how much?

The camera was named after the Brownie characters of Canadian writer Palmer Cox, and its dollar price tag is often credited with inventing the snapshot.

Beyond exposure, what creative effect does shutter speed primarily influence in a photo?

Shutter speed sets how long the sensor is exposed to light. A fast shutter freezes motion; a slow one creates intentional motion blur, used for effects like smoothing water or capturing light trails.

Eadweard Muybridge's 1878 multi-camera photographs of a running horse settled which question?

The work was funded by railroad baron Leland Stanford, and the images upended centuries of paintings that showed galloping horses with legs stretched fore and aft.

Vivian Maier, whose 150,000-plus street photographs were discovered in a storage-locker auction in 2007, spent her working life in which job?

Nanny: Maier worked for Chicago North Shore families for about 40 years. Her work was unknown in her lifetime; John Maloof bought a box of her negatives in 2007 and posted them to Flickr in 2009.

What photographic term describes the range of distance that appears acceptably sharp?

Depth of Field (DOF) is a crucial photographic concept that describes the area in front of and behind the main subject that remains in sharp focus. It can be manipulated by aperture, focal length, and subject distance.

The 'exposure triangle' in photography refers to the interplay of which three camera settings?

The exposure triangle consists of Aperture, Shutter Speed, and ISO. These three settings work together to control the total amount of light that reaches the camera's sensor, thus determining the brightness of the image.

What type of photography captures newsworthy events under an ethical code of honest, impartial portrayal?

Photojournalism is a specific form of journalism that uses images to tell a news story, typically requiring an unbiased and accurate representation of events.

Which famous author championed the Cottingley Fairies photographs as genuine?

Arthur Conan Doyle, a committed spiritualist, wrote up the photographs in the Strand Magazine in 1920; the cousins admitted in 1983 that the fairies were cardboard cutouts copied from a children's book, though one insisted the fifth was real.

What is the primary purpose of a Neutral Density (ND) filter in photography?

A Neutral Density (ND) filter reduces the intensity of light entering the lens without altering the color, allowing photographers to use slower shutter speeds or wider apertures in bright conditions.

How long before Lennon's death was Leibovitz's Rolling Stone cover of him curled around Yoko Ono shot?

Five hours: Leibovitz shot the naked Lennon curled around a clothed Ono at the Dakota on 8 December 1980; the magazine had wanted Lennon alone on the cover, but he insisted Ono be included.

The Cromemco Cyclops, the first commercially sold digital camera, debuted in 1975 in which magazine?

In which city did Robert Cornelius take his 1839 self-portrait, often called the first 'selfie'?

Philadelphia: Cornelius, a lamp manufacturer by trade, took the self-portrait outside his family's shop in October 1839 and opened one of the world's first portrait studios there in 1840.

The 1932 photo 'Lunch atop a Skyscraper' was taken during construction of which New York complex?

Rockefeller Center: the men were posed on a beam of the RCA Building, now 30 Rockefeller Plaza, on 20 September 1932 as a publicity stunt; the photographer is disputed, with Charles C. Ebbets usually credited.

What unit of measurement is typically used to describe a lens's focal length?

Focal length, which determines the angle of view and magnification, is almost universally measured in millimeters (mm) for camera lenses.

Which American photographer is renowned for black-and-white landscapes of Yosemite and the American West?

Ansel Adams was a master of black-and-white landscape photography and a pioneer of the Zone System, a technique for controlling tonal range in prints.

Steve McCurry's 1984 portrait 'Afghan Girl' was taken in a refugee camp in which country?

Canon launched the EOS (Electro-Optical System) line in 1987 with the EOS 650, the first camera built around its fully electronic EF lens mount.

Which photography genre specializes in extreme close-ups of small subjects?

Macro photography uses specialised lenses that reach 1:1 magnification or more, so a small subject is recorded life-size or larger on the sensor.

Steven Sasson's 1975 Kodak prototype, the first self-contained digital camera, stored images on what?

Cassette tape: the 8-pound prototype captured 100 x 100 pixel black-and-white images and took 23 seconds to write each one to a standard audio cassette.

In 1858, the French photographer Nadar became the first person to take photographs from what?

A balloon: over Petit-Bicêtre near Paris in 1858, Nadar had to develop wet-collodion plates in the air, and escaping gas ruined early attempts until he sealed the basket with a gas-proof cotton cover.

Which camera setting compensates for the colour temperature of the light source so that neutral greys and highlights come out looking neutral?

White balance adjusts the overall color cast of an image, correcting for different types of light, such as warm incandescent light or cool fluorescent light.

What does the acronym DSLR stand for in the context of cameras?

Digital Single-Lens Reflex: a mirror behind the lens reflects the image up to an optical viewfinder and flips out of the way during exposure, so the photographer sees exactly what the lens sees.

What photographic technique involves taking multiple photos of the same scene at different exposure settings to capture a wider dynamic range?

Exposure bracketing is often used for high dynamic range (HDR) photography, where the bracketed images are later combined to create a single image with detail in both highlights and shadows.

Which photographer popularized the concept of 'the decisive moment'?

Henri Cartier-Bresson: his 1952 book 'Images à la sauvette' appeared in English as 'The Decisive Moment', the instant when every element in a scene aligns to tell the story.

Which photographers' cooperative was founded in 1947 by Robert Capa, David Seymour and George Rodger?

Magnum Photos, founded in 1947 with Henri Cartier-Bresson among the founders, was set up so that photographers, not magazines, would own their negatives and control how their pictures were used.

What is the term for the aesthetic quality of blur in an image's out-of-focus areas?

Bokeh comes from the Japanese word 'boke' meaning blur or haze. It's highly sought after by photographers for creating visually pleasing backgrounds that make the subject stand out.

What is a photograph's orientation called when it is taller than it is wide?

Portrait orientation is taller than it is wide, named for the traditional framing of a person; the wider-than-tall format is called landscape, after scenic views.

Who is visible in Daguerre's 1838 view of the Boulevard du Temple, thought to be the first photograph of a person?

The busy street looks deserted because the multi-minute exposure erased everything that moved; only the customer and the bootblack held still long enough to register.

In digital photography, what visual tool displays the tonal range of an image, showing the distribution of shadows, mid-tones, and highlights?

A histogram is an invaluable tool for evaluating exposure, helping photographers identify if an image is underexposed, overexposed, or has a balanced tonal range.

Which photography genre requires a sealed, pressure-rated housing around the camera?

Underwater photography requires specialized waterproof housings for cameras and often additional lighting equipment to compensate for light absorption in water.

Which Associated Press photographer took 'Raising the Flag on Iwo Jima' in February 1945?

Joe Rosenthal's photo, taken on 23 February 1945, won the Pulitzer Prize the same year, and the flag shown was actually the second one raised on Mount Suribachi that day.

Who co-founded the Photo-Secession movement, advocating photography as a fine art?

Alfred Stieglitz founded the Photo-Secession in New York in 1902 with Edward Steichen and others, publishing the journal Camera Work from 1903 and showing photography as art at his 291 gallery.

What accessory stabilises a camera against shake in low light or long exposures?

Tripods are essential for sharp images when using slow shutter speeds, telephoto lenses, or for precise compositional control in landscape and architectural photography.

What is selectively lightening or darkening parts of an image to control local exposure called?

Dodging lightens areas, and burning darkens them. These techniques originated in the darkroom for film photography and are now simulated in digital editing software.

What is the primary job of the petal- or tube-shaped hood that screws onto the front of a camera lens?

Lens hoods are essential accessories, especially when shooting into the sun or with strong side lighting, to improve contrast and image quality by minimizing unwanted light.

Which photographic genre focuses on capturing candid moments of everyday life in public places?

Street photography often aims to capture genuine human emotions and interactions, telling stories about urban environments and public spaces.

What optical defect shows as purple or green fringes along high-contrast edges?

Chromatic aberration occurs because a lens bends each wavelength slightly differently, so colours focus at different points; it shows most at high-contrast edges and is corrected with low-dispersion glass or software.

Which photography genre uses equatorial tracking mounts during long exposures?

Astrophotography frequently involves specialized equipment and techniques, like tracking mounts, to achieve stunning images of celestial objects and phenomena.

In a digital photo, what does the 'EXIF' metadata standard's name stand for?

Exchangeable image file format: the EXIF standard, introduced by JEIDA in 1995, embeds shutter speed, aperture, ISO, date, time and even GPS coordinates in the image file.

Which two thinkers of the 4th century BCE left the earliest written records of the camera obscura?

Aristotle and Mozi: Aristotle noted the sun's crescent image cast through small gaps during an eclipse, and the Chinese Mohist text describes an inverted image formed by light passing through a pinhole.

The 1861 three-colour photograph made for James Clerk Maxwell's lecture was actually taken by whom?

Thomas Sutton shot the tartan ribbon through red, green and blue filters for Maxwell's 1861 Royal Institution lecture; Maxwell had proposed the three-colour method in 1855, and the insensitive emulsions made the result crude.

The CCD sensor was invented at Bell Labs in 1969 by George E. Smith and which colleague?

Willard Boyle and Smith sketched the CCD in 1969 as a memory device and shared the 2009 Nobel Prize in Physics for it; their colleague Michael Tompsett later showed it could work as an imaging sensor.

The first photograph published on the web, in 1992, showed which CERN group?

Tim Berners-Lee uploaded the image, opening the door to photo sharing sites from Flickr to Instagram.
