Spiro Bolos

Country: United States
Birth: 1967

Spiro Bolos is a Chicago-based street photographer who spends an inordinate amount of time on public transportation, especially since casting off his former minivan-centered life in suburbia.

His chosen career is that of a social studies teacher and he became interested in American photography while teaching an American Studies course, first focusing on the documentary images of the Civil Rights era and then becoming preoccupied with the more artistic efforts of photographers such as Gordon Parks and William Eggleston. As a historian, he had an initial impulse to record a vision of the present era through the human characters surrounding him.

But he had also seen the intriguing BBC documentary of Vivian Maier and attended a lecture by street photographer Brian Sokolowski, who demonstrated that an image of a complete stranger could function as a self-portrait. And so, with his phone ever-presently in hand, he started making photographs long before he was acquainted with Szarkowski's famous reference to "mirrors" and "windows".

His subjects are usually blind to his stealthy process, perhaps because of the ubiquity of smartphones, as well as his desire to capture, as Strand put it, a "quality of being". But in a society increasingly surveilled, a moment of recognition occasionally surfaces in the subject’s eyes.

More Great Photographers To Discover

Bryan Adams
Canada
1959
Adams works as a photographer as well as musician, aside from being published in British Vogue, L'uomo Vogue, Harper's Bazaar, Esquire, Interview magazine and i-D, among others, he has also shot advertising campaigns for Guess Jeans, Sand, Converse, Montblanc, John Richmond, Fred Perry, and more recently for Escada. He has won Lead Awards twice in Germany for his fashion work, most recently June 2012 and previously in 2006. Other photographic endeavours include founding the art fashion Zoo Magazine, based in Berlin, Germany for which he shoots for regularly. His first book of photos will be released by Steidl in 2012 entitled Exposed. Previous published collaborations include; American Women June 2005, for Calvin Klein in the United States; proceeds from this book went to Memorial Sloan–Kettering Cancer Center in New York City for their breast cancer research for programs, and Made in Canada December 1999 for Flare Magazine in Canada; proceeds went to the Canadian Breast Cancer Foundation. Both books were dedicated to his friend Donna, who died of the disease. As a photographer, Adams has worked with many of his musical peers, including Lana Del Rey, The Who, Sting, Shania Twain, Mick Jagger, Arcade Fire, Ray Charles, Tina Turner, Rod Stewart, Robert Plant, Take That, Joss Stone, Plácido Domingo, Sarah McLachlan, Celine Dion, Billy Idol, Moby, Lindsay Lohan, Amy Winehouse, Annie Lennox, Peter Gabriel, Bryan Ferry, Lenny Kravitz, Die Antwoord, and Morrissey to name a few. On 27 November 2000 Adams played onstage with The Who at the Royal Albert Hall. A DVD of the concert was issued. Adams photographed the band and his photos appear in the DVD booklet. In 2002, Adams was invited, along with other photographers from the Commonwealth, to photograph Queen Elizabeth II during her Golden Jubilee; one of the photographs from this session was used as a Canadian postage stamp in 2004 and again in 2005 (see Queen Elizabeth II definitive stamp (Canada)), another portrait of both Queen Elizabeth II and Prince Philip is now in the National Portrait Gallery in London. Adams supports the Hear the World initiative as a photographer in its aim to raise global awareness for the topic of hearing and hearing loss. He photographed Michael J. Fox and Tatjana Patitz in the 2011 Carl Zeiss AG company calendar in New York City in the summer of 2010. The focus was about the size difference of the subjects in a comedic presentation. In 2011, Adams provided the cover art for Lioness: Hidden Treasures, a posthumous release by Amy Winehouse.Source: Wikipedia Rock Icon Bryan Adams' lifelong interest in photography turned into a vocation when he began shooting for fashion magazines and advertisers more than a decade ago. But it's not all models and celebrities: He most recently turned his lens on 40 British soldiers returning from Iraq and Afghanistan. His series Wounded: The Legacy of War, the subject of a 2013 book from Steidl and an exhibit at London’s Somerset House on display this month through Jan. 25, showcases the brutal (and all too common) injuries incurred in battle. "I didn't like the fact that people were getting so badly hurt, so many people were killed, were displaced, forgotten. This is my statement," says Adams, 55. On the legacy of the images, he says, "I hope [people] realize that these guys made an incredible sacrifice. War is disgusting and this is the result of what happens when we decide to beat each other up."Source: Billboard
Frederick Sommer
United States
1905 | † 1999
Frederick Sommer (September 7, 1905 – January 23, 1999), was an artist born in Angri, Italy and raised in Brazil. He earned a M.A. degree in Landscape Architecture (1927) from Cornell University where he met Frances Elizabeth Watson (September 20, 1904 – April 10, 1999) whom he married in 1928; they had no children. The Sommers moved to Tucson, Arizona in 1931 and then Prescott, Arizona in 1935. Sommer became a naturalized citizen of the United States on November 18, 1939. Considered a master photographer, Sommer first experimented with photography in 1931 after being diagnosed with tuberculosis the year prior. Early works on paper (starting in 1931) include watercolors, and evolve to pen-and-ink or brush plus drawings of visually composed musical score. Concurrent to the works on paper, Sommer started to seriously explore the artistic possibilities of photography in 1938 when he acquired an 8×10 Century Universal Camera, eventually encompassing the genres of still life (chicken parts and assemblage), horizonless landscapes, jarred subjects, cut-paper, cliché-verre negatives and nudes. According to art critic Robert C. Morgan, Sommer's "most extravagant, subtle, majestic, and impressive photographs—comparable in many ways to the views of Yosemite Valley’s El Capitan and Half Dome by Ansel Adams—were Sommer’s seemingly infinite desert landscapes, some of which he referred to as 'constellations.'" The last artistic body of work Sommer produced (1989–1999) was collage-based largely on anatomical illustrations. Frederick Sommer had significant artistic relationships with Edward Weston, Max Ernst, Aaron Siskind, Richard Nickel, Minor White, and others. His archive (of negatives and correspondence) was part of founding the Center for Creative Photography in 1975 along with Ansel Adams, Harry Callahan, Wynn Bullock, and Aaron Siskind. He taught briefly at Prescott College during the late 60s and substituted for Harry Callahan at IIT Institute of Design in 1957–1958 and later at the Rhode Island School of Design. In 1934, Frederick Sommer visited Los Angeles. Walking through the art museum one day, he noticed a display of musical scores. He saw them not as music, but as graphics, and found in them an elegance and grace that led him to a careful study of scores and notation. He found that the best music was visually more effective and attractive. He assumed that there was a correlation between music as we hear it and its notation; and he wondered if drawings that used notational motifs and elements could be played. He made his first “drawings in the manner of musical scores” that year. (After reviewing this text, Fred asked that the author refer to his scores “only” in this way. When the author suggested that it was perhaps too long to be repeated throughout the text, he laughed and said, “Well, use it at least once.”) Although people knew of his scores, and occasionally brought musicians to his house to play them, no one ever stayed with it for long. In 1967, both Walton Mendelson and Stephen Aldrich attended Prescott College, Prescott, Arizona, where Sommer was on the faculty. They barely knew of his reputation as a photographer, and nothing of the scores. Towards the end of September he invited them to his house for dinner, but they were to come early, and Mendelson was to bring my flute. “Can you play that?” he asked, as they looked at one of the scores, framed, and sitting atop his piano. With no guidance from him, they tried. Nervous and unsure of what they were getting into, they stopped midway through. Mendelson asked Aldrich where he was in the score: he pointed to where Mendelson had stopped. They knew then, mysterious though the scores were, they could be played. On May 9, 1968, the first public performance of the music of Frederick Sommer was given at Prescott College. Sommer had no musical training. He didn't know one note from another on his piano, nor could he read music. His record collection was surprisingly broad for that time, and his familiarity with it was thorough. What surprised Mendelson and Aldrich when they first met him were his visual skills: he could identify many specific pieces and almost any major composer by looking at the shapes of the notation on a page of printed music. Of Sommer's known works, his drawings, glue-color on paper, photographs, and writings, it is only these scores that have been a part of his creative life throughout the entirety of his artistic career. He was still drawing elegant scores in 1997. And like his skip reading, they are the closest insight to his creative process, thinking and aesthetic. Bruce Silverstein Gallery is the New York representative of the Frederick & Frances Sommer Foundation.Source: Wikipedia Frederick Sommer was an artistic polymath, with deep interests in painting, drawing, photography, sculpture and collage. With his work he intended to engage the world formally, to harvest its chance gifts, decontextualizing and rearranging found images and objects according to often shocking visual affinities. The artist played with a wide variety of forms, textures and scale to create startling compositions amid objects and sites others found too insignificant to notice. Sommer was intent on expanding the limits of where beauty could be found, and after viewing a display of original musical scores, he began to formulate his own theories correlating the graphic design to the sound of musical scores. Alongside many great artists of the period including Edward Weston, Max Ernst, Man Ray and Aaron Siskind, Sommer created a unique and avant-garde body of work formulated from his interest in Surrealism. His works have been exhibited by the world’s most important institutions, including the George Eastman House, Rochester; The J. Paul Getty Museum, Los Angeles; Delaware Art Museum; Serpentine Gallery, London; Charles Egan Gallery, New York; Philadelphia College of Art; Washington Gallery of Modern Art, Washington D.C.; Pasadena Art Museum, California; Museum of Modern Art, New York; Institute of Design, Chicago; Zimmergalerie Franck, Germany; and the Los Angeles County Museum of Art. Work by the artist is represented in major museum collections internationally such as the Metropolitan Museum of Art, New York; Smithsonian Institution, Washington D.C.; Art Institute of Chicago; Museum of Modern Art, New York; Los Angeles County Museum of Art; Museum of Fine Arts, Boston; National Gallery of Art, Washington D.C.; Maison Européenne de la Photographie; George Eastman House, Rochester; and the Victoria and Albert Museum, London. Sommer’s work has been published widely. Noteworthy publications include Frederick Sommer: Photography, Drawing, Collage (2005), The Mistress of the World Has No Name: Where Images Come From (1987), Frederick Sommer at Seventy Five, a Retrospective (1980), and Venus, Jupiter and Mars: The Photographs of Frederick Sommer (1980).Source: Bruce Silverstein Gallery
William Gedney
United States
1932 | † 1989
William Gale Gedney (October 29, 1932 – June 23, 1989) was an American documentary and street photographer. It wasn't until after his death that his work gained momentum and is now widely recognized. He is best known for his series on rural Kentucky, and series on India, San Francisco, and New York shot in the 1960s and 1970s. William Gedney was born in Greenville, New York. He studied at Pratt Institute in Brooklyn, New York. In 1955 he graduated with a BFA in Graphic Design and began work with Condé Nast. During his lifetime, Gedney received several fellowships and grants, including a John Simon Guggenheim Memorial Foundation fellowship from 1966 to 1967, a Fulbright Fellowship for photography in India from 1969 to 1971, a New York State Creative Artists Public Service Program (C.A.P.S.) grant from 1972 to 1973; and a National Endowment for the Arts grant from 1975 to 1976. In a career spanning the late 1950s to the mid-1980s, he created a large body of work, including a series documenting local communities during his travels to India, San Francisco, Brooklyn, and New York shot in the 1960s and 1970s. He is also noted for night photography, principally of large structures, like the Brooklyn bridge and architecture, and architectural studies of neighborhoods quiet and empty, at the night. In 1969, he started teaching at Pratt Institute, though later in 1987, two years before his death, he was denied tenure. Gedney's work has been exhibited in numerous group shows, including Museum of Modern Art shows, Photography Current Report in 1968, Ben Schultz Memorial Collection in 1969, and Recent Acquisitions in 1971; as well as Vision and Expression,George Eastman House, and Rochester Institute of Technology, in 1972. However, he remained a recluse, had only one solo exhibition during his lifetime. Despite receiving appreciation from noted photographers of the time, Walker Evans, Diane Arbus, Lee Friedlander, and John Szarkowski, he remained an under-appreciated artist of the generation. He didn't manage to get any of his eight-book projects published. William Gedney died of complications from AIDS in 1989, aged 56, in New York City and is buried in Greenville, New York, a few short miles from his childhood home. He left his photographs and writings to his lifelong friend Lee Friedlander. In time, Friedlander's efforts, which had earlier led to the revival of E. J. Bellocq's works, chartered posthumous revival of Gedney's work. An extensive collection of his work, including large photographic prints, work prints, contact sheets, negatives, sketchbooks, notebooks and diaries, correspondence, and other files are housed at the Rubenstein Library, Duke University, Durham, North Carolina.Source: Wikipedia
George Zimbel
United States / Canada
1929
George S. Zimbel (born July 15, 1929) is an American-Canadian documentary photographer. He has worked professionally since the late 1940s, mainly as a freelancer. He was part of the Photo League and is one of its last surviving members. Born in Massachusetts, he settled in Canada about 1971. His works have been shown with increasing frequency since 2000, and examples of his work are part of several permanent collections including the Museum of Modern Art and the Montreal Museum of Fine Arts. George Zimbel has been described as a humanist. He has published several books of his photographs and in 2016 was the subject of a documentary retrospective film co-directed by his son Matt Zimbel and distributed by the National Film Board of Canada. Born George Sydney Zimbel in Woburn, Massachusetts, son of a dry goods store owner, he attended Woburn High School and was the school's yearbook photographer. He later studied at the Photo League under John Ebstel. George Zimbel then enrolled in Columbia University in New York where he became the school's news photographer. There he met art student Garry Winogrand and introduced Winogrand to photography. They used the school's darkroom late at night to avoid crowding at other times of the day, and they called themselves the "Midnight to Dawn Club". Both Zimbel and Winogrand later both studied under Alexey Brodovitch at the New School for Social Research on scholarships in 1951. He next met Edward Steichen, the then curator of the Museum of Modern Art who showed Zimbel original prints by early masters of photography, and this sealed his decision to take up photography as a career. On Steichen's advice, he had a stint as a photographer with the US Army and spent 2 years in Europe during the restoration period following World War II. On his return to America, he became a freelance photographer. One of his early opportunities was the famous Marilyn Monroe shoot on Lexington Avenue in 1954 to promote her film The Seven Year Itch, at which Monroe wore her famous white dress. Zimbel never sold any of these images and packed them away until 1976, whereupon he printed them and began to show them in solo exhibitions. He was married to Elaine Sernovitz in 1955. A professional writer, she has collaborated with George Zimbel on travelogues and other works. George and Elaine Zimbel had four children including jazz musician Matt Zimbel, founder of Manteca. Matt Zimbel co-produced and co-directed (with Jean-Francois Gratton) a documentary film about his father called Zimbelism, released in 2016. In 1971, Zimbel and his family moved to the small community of Argyle Shore, Queens County, Prince Edward Island where they raised animals for the next 10 years at a farm they called "Bona Fide Farm". After their children moved away, he and his wife relocated to Montreal, where they still reside. Though he was widely published in publications such as the New York Times, Look, Redbook and Architectural Digest in the 1950s and 60s, he did not become widely recognized until a retrospective exhibition of his work was mounted at the Institut Valencià d'Art Modern in Spain in 2000. Since then he has had several major shows around the world.Source: Wikipedia The American-Canadian humanist photographer George S. Zimbel is one of the last elders of photography faithful to the legacy of the Photo League, who in the fifties imbued their pictures with a personal commitment towards the people and the social landscapes they documented. Zimbel’s work is collected by major museums internationally, he has published numerous books and in 2016 he was the subject of an award winning feature documentary on his work called Zimbelism. George’s collection is now managed by his children. The collection consisting of prints printed by George, negatives and colour slides is in the process of being cataloged. Cataloging of the prints has been completed. The thousands of colour slides, and hundred of thousand negatives will be an on going project. In an era of increased manipulation of the photographic image by computer technology, Zimbel’s commitment to the “straight” photograph has become stronger. He sees the early 21st century as a period in which classic photography will have it’s last flowering. "My work begins with recording an image, but it is not finished until I have made a fine print. That is my photograph. A lot goes into a finished documentary photograph: a very personal view of life, a knowledge of technique, and of course, information. It is the information that grabs the viewer, but it is the photographer’s art that holds them." – George S. ZimbelSource: georgezimbel.com
Alesya Osadchaya
Russia Federation
1990
Alesya Osadchaya was born in October of 1990 in Moscow, Russia. She studied veterinary medicine at the Moscow Veterinary Academy. Currently, he also works as a teacher in the field of veterinary entrepreneurship. The fascination with photography came from childhood. Dad taught her to handle the camera, later she got carried away with photography seriously and began to earn money by taking pictures - portrait and reportage. After graduation, the institute began to travel and take pictures of more scenery and travel reports. Travel and photography are closely related. Alesya rarely uses the services of travel agencies and travels alone. Always takes a camera with her. Through photographs, she shows the fragility of man compared to the forces of nature. Statement: No wonder they say that the most cool photos are obtained at a time when the elements are raging. Nature opens on the new side. In bad weather, few people can force themselves to leave the warm bed and go to meet the unknown. At this time, and people who are on the street once pretend to wear "masks". They are busy with more important things - how not to get wet, do not mess up your hair, save your property, and even the safety of your life, after all. But these are not all. However strange it may sound, I am inspired by the vagaries of nature: storms, hurricanes, tornadoes, storms. As a child, I reviewed a bunch of BBC films (and not only) about similar natural phenomena. Probably, therefore, at such moments in the head immediately the plots for photographs are born - a good look. But even in the quietest weather one can find "moments of strength". With my capture I want to show the greatness of nature, its beauty, strength and scale in comparison with fragility and human life.
Barbara De Vries
Netherlands
The Dutch artist Barbara de Vries studied at the Rietveldacademie and the St. Joostacademie graphic art, industrial design and theater design. Although she worked with several famous theatres, Barbara finally got specialised in photography. The atmosphere in her work is a midway between fantasy and reality. Her images are mostly blurred, out of focus, with glimpses of reality. The Dutch curator Maarten Bertheux wrote as follow about her work. ‘Work of Francis Bacon and Marlene Dumas are relevant for the work of Barbara de Vries. Her work contain of digital reworked photographic material printed on Japanese paper. She combines and deforms her images in order to create her layered images. When she uses soft contours it brings in mind an aquarellist way of painting, a style De Vries used frequently before she started to use the computer as a tool in her photographic work. Her background as a stage designer has also influenced her actual work. This experience appears in the theatrical and dramatic setting and in the way she manipulates the light. In the photographic work there can be clear definition of space, but equally she uses an indistinct space that can vary from a sfumato-like space to a space where figures seem to float in. The figures are constructed out of several limbs and elements that are reconstructed in a new way, creating a new figuration. It seems as it is De Vries’ capability to creep under the skin of her model and analyzing the basic psycho logic characteristics’. Barbara de Vries' photography evoke feelings of hope, desire and consolation. Source: Morren Galleries

Exclusive Interview with Guillaume Bonn
With his latest book Paradise, Inc., celebrated documentary photographer Guillaume Bonn takes us deep into the heart of East Africa, where the promises and failures of wildlife conservation collide. Far from offering a romanticized vision of nature, Bonn’s work confronts us with urgent realities: the tensions between local communities and conservation policies, the sacrifices of rangers on the frontlines, and the long-lasting impact of human activity on fragile ecosystems. Spanning more than two decades of fieldwork, the project blends powerful imagery with investigative depth, raising difficult but necessary questions about transparency, accountability, and the Western-led models that dominate conservation. Enriched by the voices of those too often left out of the conversation—including a preface by Maasai leader Ezekiel Ole Katato and an introduction by journalist Jon Lee Anderson—Paradise, Inc. is both a stunning visual journey and a call to action. In the following interview, Guillaume Bonn reflects on the making of Paradise, Inc., the ethical dilemmas at the heart of his work, and the urgent need to rethink our approach to conservation in East Africa and beyond.
