1906: Availability of panchromatic black and white film and therefore high quality color separation color photography. PAINTING OF THE WEEK - Ruins of the Holyrood Chapel by Moonlight, oil on canvas, 1824, Louis Daguerre. G+ #Read of the Day: The Daguerreotype - The daguerreotype, an early form of photograph, was invented by Louis Daguerre in the early 19th c. The first photograph (1826) - Joseph Niepce, a French inventor and pioneer in photography, is generally credited with producing the first photograph.
Easy Peasy Fact:Following Niepcea€™s experiments, in 1829 Louis Daguerre stepped up to make some improvements on a novel idea. Chapter 1 takes place between February and September 1933, and introduces young Woody Hazelbaker as a junior member of a Wall Street law firm in trouble thanks to the Depression. When Woody Hazelbaker got there at the end of the 1920s, he thought it grand, even after the breadlines that followed the Stock Market Crash in October a€?29: New York was Americaa€™s greatest and most bustling city, its port the gateway to the world.
Owney Madden was no scientific genius like Professor Moriarty, but he handled things the same way. In Chapter 2, during the autumn of 1933, Woodya€™s deepening involvement with Owney Madden jars his cultural preconceptions loose when he visits the flagship of Maddena€™s nightclubs, the Cotton Club in Harlem. Club DeLuxe opened in 1920 at 142nd and Lenox Avenue, but Owney Madden bought it three years later and turned it into the Cotton Club, offering not only booze but the best jazz to be had, launching meteoric careers for Fletcher Henderson, Duke Ellington, Cab Calloway, and others. Bleecka€™s had opened as a speakeasy in the mid a€™20s, and though ruled with an iron hand by its irascible owner Jack Bleeck, it was instantly and permanently adopted by the newspapera€™s editors and reporters. Bleecka€™s saloon was a few paces from the Herald Tribunea€™s back door, a stonea€™s throw from Seventh Avenue. Nevertheless Walker and Beebe become important resources about New York social life for Woody, their perspectives stretching from the 1920s into the a€™40s. Prohibition ends December 5th, 1933, just about when Harvard Club librarian Earle Walbridge a€” later a€?The Sussex Vampire,a€? BSI, and at his death in 1962 the only man whoa€™d attended every BSI dinner back to its a€?first formal meetinga€? in June a€™34 a€” takes Woody to Christ Cellaa€™s speakeasy on East 45th Street, where he meets Christopher Morley and some of his friends just as the nascent Baker Street Irregulars are about to burst out into the open. In Chapter 3, over the winter, Woody is incurably bitten by the Sherlock Holmes bug, but his work for Owney Madden is not done. New York Police Commissioner Grover Whalen estimated in 1929 that there were 32,000 illegal speakeasies in the city. It will take all of $5.00 to pay for a dinner for two at Christ Cellaa€™s little hideaway restaurant in the basement of a brownstone front at 144 East Forty-fifth Street, just a block from Grand Central Palace.
Cella, sleek, brown-eyed and chunky, is a born innkeeper, though he gives mural painting as his profession.
But in the early 1930s it was a speakeasy, where around a table in the kitchen Chris Morley and his Three-Hour Lunch Club friends met to drink, laugh and talk, gestating The Baker Street Irregulars. He sat back and sipped the drink that Chris brought him, watching the room through half-closed eyes. The crew Woody met that day were about to bring the BSI out into the open, once Repeal took effect. In Chapter 4, stretching from spring to autumn, 1934, a chance meeting with Lucius Beebe at Bleecka€™s propels Woody into a more cosmopolitan circle at the Plaza Hotela€™s Mena€™s Bar. It still exists a€” known now as the Oak Room: a€?by far the hotela€™s most significantly historic space, virtually unchanged since the day the Plaza opened for business, Oct.
It was then known as the Mena€™s Bar, an all-male enclave said to be the favorite room of the hotela€™s architect, Henry J. For the next 70 years, it was patronized by some of the most celebrated folk of the 20th century. Alsop was younger than me, short and pudgy with a pale face and dark-rimmed glasses beneath thin brown hair.
When the National Organization for Women decided to challenge the men-only policies at restaurants and clubs, it chose the Oak Room, which refused to serve women at lunch on weekdays, as a test case, knowing the kind of upscale publicity it would lend to the cause.
The Mena€™s Bar Oak Room is sadly the only venue this chapter that still exists (with a close escape a few years ago when the Plazaa€™s barbarian redeveloper intended to gut it). If Ia€™d seen the place empty I might have wondered what the fuss was about, but it was busy when we arrived.
Shake well with ice cubes and dash of orange bitters, twist of lemon peel and just a touch of sugar. Owner John Perona and maA®tre da€™ Frank Carino made El Morocco, once a speakeasy, the place to go and be seen for all manner of celebrities, including Broadway and Hollywood stars. People kept stopping by to speak to Beebe, hoping to find themselves in his column the next day. I must have snickered, because he went on reprovingly: a€?Believe it or not, fortunes and careers are made by sitting at the right table.
Beebe basked, and started to reply, when suddenly behind me a silvery voice spoke out of the blue. In Chapter 5, December 1934 through the next several months, Woody attends the first Baker Street Irregulars dinner at Christ Cellaa€™s and solidifies his position in Chris Morleya€™s BSI.
Suddenly, with an explosive burst so nobody would miss his entrance, Alexander Woollcott arrived.
Chapter 6 stretches from the spring of 1935 to New Yeara€™s Eve in 1936, more than a year and a half of political turbulence in America, and in Woodya€™s life as well. Woody attends the a€™36 annual dinner at Christ Cellaa€™s a€” neither he nor anyone else there realizing that it will be the last for four years. In the early 1930s the New Schoola€™s snazzy new Greenwich Village building, with an informal left-wing faculty and ties to outfits like the John Reed Clubs, was just the place for a Wall Street lawyer to validate his anti-Wall Street feelings, as long as he could duck.
Chris Morley looked down the table at me, elbows propped up on it and chin resting on tented hands. After taking Diana to see After the Thin Man on New Yeara€™s Eve, he finds himself finally, truly, completely alone with Diana a€” and this time all escape cut off.
And Diana snatched the paper from me, dropped it on top of the others, and pushed the entire stack off onto the floor. The consolation of BSI seems to be denied: there is no Annual Dinner in 1937 (nor will be in 1938 either).
Pratt stood only 5'3", had thin receding red hair, and wore round-rimmed eyeglasses with tinted lenses.
In 1937 even Irregulars have foreign dangers on their minds, and not just those convening at the Mena€™s Bar Sundays for martinis and chicken soup.
The British Empire may no longer be able to regard itself, as it reasonably could until 1914, as the leading power of the world; since we let opportunity slip through our fingers in the early twenties, it may be doubted if the world has had any leading power, which may be one of the things that is the matter with it.
When the crisis that ended with the abdication of Edward VIII had been quickly and smoothly settled the English indulged in a good deal of excusable self-congratulation. Americans are not particularly proud of their countrya€™s isolation from world politics, but do not see what else can be done about it at the moment. People who try to describe the Czechoslovak Republic in its nineteenth year seem driven to metaphor. Diana has her own response: use her family money to fund groups opposed to Nazi aggression. Everyone did after Benny Goodman took the Paramount Theater by storm, people clamoring for tickets nearly rioting in Sixth Avenue. The first time I heard them do a€?Moonglowa€? it was three in the morning, Diana and me listening to the sweet haunting music through a dreamlike haze of smoke and alcohol.

Niepcea€™s photograph shows a view from the Window at Le Gras, and it only took eight hours of exposure time!The history of photography has roots in remote antiquity with the discovery of the principle of the camera obscura and the observation that some substances are visibly altered by exposure to light. Again employing the use of solvents and metal plates as a canvas, Daguerre utilized a combination of silver and iodine to make a surface more sensitive to light, thereby taking less time to develop. He gets a chance (and despite trepidations, takes it) to hang on by undertaking work for a clandestine client, the kind his firm would never accept in good times: bootlegger Owney Madden, and his No.
What I knew about them came from Walter Winchell in the Mirror and movies like Little Caesar.
Owney Madden was in the bootlegging business and everything else that went with it, including his chief aide and enforcer Big Frenchy DeMange.
Black entertainers performing for strictly white audiences reflects the eraa€™s racial segregation, but the Cluba€™s showcasing of brilliant talent helps make jazz a national treasure. Beside the entrance was a tarnished brass plaque saying a€?Artists and Writersa€? a€” the admission policy? It finally comes to an end a year after it started, with Madden retiring from the rackets in New York and departing for a new life elsewhere.
Lexington Avenue could still be followed south to 45th Street; and on 45th Street Chris Cellini should still be entertaining his friends unless a tidal wave had removed him catastrophically from the trade he loved . The kitchen was the supplement to the one small dining room that the place boasteda€”it was the sanctum sanctorum, a rendezvous that was more like a club than anything else, where those who were privileged to enter found a boisterous hospitality undreamed of in the starched expensive restaurants, where the diners are merely so many intruders, to be fed at a price and bowed stiffly out again.
The flash of jest and repartee, the crescendo of discussion and the ring of laughter, came to his ears like the echo of an unforgettable song. On the far side, back to the wall, was a burly man with a broad hearty face, thick brown hair, and lively eyes full of mischief. 1, 1907,a€? wrote the Times five years ago (a€?What Would Eloise Say?a€? by Curtis Gathje, Jan.

The Biltmore Hotel is gone, turned into office space despite protected-landmark status at the time. I froze, then scuttled out sideways like a crab, and turned to face the most stunning girl Ia€™d ever seen.
At Decembera€™s BSI dinner, he observes a Worlda€™s Champ and a Fabulous Monster, both of whom he will meet again, but more importantly he makes a new friend for life in Basil Davenport.


Everybody knew his face from magazines and high piping voice from the radio a€” and some people hated both. Woollcott and Morley might be rival bookmen, but Chris didna€™t look half as annoyed as Bob. One of his dislikes was Alexander Woollcott, whose presence at the December 7, 1934, annual dinner Leavitt always insisted was uninvited, unwanted, and obnoxious. Woody can use one: his regained professional calm is jolted the self-possessed young heiress he met at El Morocco has daddy switch his legal work to Woody. The still young phenomenon of radio carries not only FDRa€™s reassuring Fireside Chats into American homes, but also the demagoguery of former Louisiana Governor, now Senator, Huey a€?Kingfisha€? Long, and the maverick priest Father Charles Coughlin. Not only cana€™t he get started with Diana, he doesna€™t even seem to have her attention when theya€™re together a€” and is silly enough to look for answers in the movies, as if life were one big screwball comedy. For some it was Shirley Temple, for others Nelson Eddy and Jeanette MacDonald, for more than you could count Fred Astaire and Ginger Rogers. Diana is beautiful and wealthy, but comes with a father-in-law whose politics Woody can barely abide. But Woody and some others, instead of shrugging, organize occasional Irregular three-hour lunches of their own.
But into those sessions now is injected an isolationist note even Anglophiles like Elmer and Woody cana€™t ignore, from Chris Morleya€™s brother Felix, a€?the Second Garrideb,a€? editor of the Washington Post sharply critical of FDR and his policies. Elmer Davis gives up fiction to write serious foreign policy articles for Harpera€™s Magazine, about the dangers in store for an indifferent and unprepared America.
Not only had they disposed of a troublesome situation with less fuss than almost any other nation would have made over ita€”the reaction abroad, they told one another, had demonstrated that all men of good will realized that the stability of England was vitally essential to the stability of a somewhat unsteady world.
You still meet Europeans who ask you why America does not come into the League and help to do something about world peace; but most of them, after recent collapses of the system of collective security, know why, and only wish that they could do as we do. President BenA?s, in his radio broadcast last Christmas Eve, said that a€?Czechoslovakia stands like a lighthouse high on a cliff with the waves crashing around ita€”a democracy that has the mission to keep the flag of peace, freedom, and toleration flying in Central Europe.a€? The propaganda German radio stations and newspapers have been pouring out for months sees the country as a a€?sally port of Bolshevism,a€? And K.
Porta (1541-1615), a wise Neapolitan, was able to get the image of well-lighted objects through a small hole in one of the faces of a dark chamber; with a convergent lens over the enlarged hole, he noticed that the images got even clearer and sharper. Though he is most famous for his contributions to photography, he was also an accomplished painter and a developer of the diorama theatre.
As far as is known, nobody thought of bringing these two phenomena together to capture camera images in permanent form until around 1800, when Thomas Wedgwood made the first reliably documented although unsuccessful attempt.
Member of Hudson Dusters gang, convicted twice of safecracking with 13 arrests total, including one for murder. And as winter approaches Woody makes a third discovery that will change his life for good, this time at the Harvard Club library: Vincent Starretta€™s brand-new and magically evocative book, The Private Life of Sherlock Holmes.
Ellingtona€™s a€?Cotton Club Stompa€? captured the beat and drive as well as the venue and era. Astora€™s Horse (1935) are available today; The Night Club Era especially evokes the New York popular culture in which the BSI gestated and was being born in the early a€™Thirties. Woody has weathered the Depressiona€™s worst year and learned a lot a€” but the ending of his clandestine association with Owney and Frenchy DeMange leaves him feeling blue.
One was opened in a brownstone at 144 East 45th Street in 1926 by an Italian immigrant named Christopher Cella, whose boyhood friend Mike Fischetti was on the NYPDa€™s a€?Italian Squad,a€? one of the toughest cops in town. Although there were no familiar faces seated round the big communal table, the Saint felt the reawakening of an old happiness as he stepped into the brightly lighted room, with the smell of tobacco and wine and steaming vegetables and the clatter of plates and pans. It was the same as it had always beena€”the same humorous camaraderie presided over and kept vigorously alive by Chrisa€™s own unchanging geniality.
Its German Renaissance design features walls of sable-dyed English oak, frescoes of Bavarian castles, faux wine casks carved into the woodwork and a grape-laden chandelier topped by a barmaid hoisting a stein. Cohan, the Broadway hyphenate, a composer-playwright-actor-producer-theater owner, and the only person ever awarded a Congressional Medal of Honor for a song, the rousing World War I anthem, a€?Over There.a€? Cohan made the Oak Room his pre-theater headquarters, his preferred table being a booth in its northwest corner. There was an air of privilege about him even in the way he held his drink and his cigarette.
The waitersa€™ response was to remove the table, leaving the women sitting awkwardly in a circle.
Banquettes along the walls, and backs and seats of chairs, were in the blue zebra print identifying El Morocco in newspaper pictures. At a podium outside the arch, the maA®tre da€™ greeted us and led us inside, where Beebe was perched on a stool watching a bartender perform with a cocktail shaker. On his favor and discretion hang feuds, romances, careers, ambitions, the very foundations of the most bitterly jealous and competitive social hierarchy of our generation. She looked at me with indignation, rubbing the top of one gold-sandaled foot against the back of her other ankle. His acquaintance with Elmer Davis moves beyond the BSI into other realms, and Woody comes to understand what Morley had told him: they do all have Sherlock Holmes in common, but the BSI is primarily about friendship. But a September 9, 1938, letter from Elmer Davis to Vincent Starrett gives a different impression: an older friend of Morleya€™s than Leavitt, Davis took up merrily with Woollcott that night.
While Elmer Davis worries about a native despot poised for the a€™36 elections, Woodya€™s worries are closer to home. For me, it was one romantic comedy of William Powella€™s after another until my mind turned to mush. Yet Ambrose Converse is also his most important client now, as if Jimmy Stewart had gone to work for old buzzard Potter in Ita€™s a Wonderful Life. The big stories were the Prince of Walesa€™ abdication, Italy invading Ethiopia, and FDRa€™s new term. Four columns were marching on the city with a a€?fifth columna€? inside it waiting to strike like a snake. To Basil Davenport, Peter Greig, Earle Walbridge, and Dave Randall are added two more, one a kinsprit already, the other someone who will become important to Woody as the world drifts closer to war.
Wiry and muscular, with a neatly clipped mustache, he resembled a wary bird whoa€™d bite off any finger poked in his direction.
I believe that every democratic nation in Europe today would get out of Europe and stay out if it could; out of the neighborhood of Germany .
But for them both, 1937 is their newlywed year a€” out on the town, taking in the movies, seeking out the coolest jive joints with the hottest jazz, and going dancing with the Age of Swing in full blast. One night I overheard a callow youth say something to his girl about a€?shaming the old folks off the floor,a€? and realized in dismay that he meant me. He said he could play drunk because he practiced drunk, and he sure could play, but we were watching self-destruction right before our eyes.
We went on that way into 1938, celebrating our first anniversary without even a BSI dinner to break the mood.
Schulze mixes chalk, nitric acid, and silver in a flask; notices darkening on side of flask exposed to sunlight. A daguerreotype, produced on a silver-plated copper sheet, produces a mirror image photograph of the exposed scene. For the green and rather innocent Woody, Madden, DeMange, and the work prove quite an education. Then decades later, in Francis Ford Coppolaa€™s 1984 movie The Cotton Club, its life and times were recreated superbly, with Bob Hoskins and Fred Gwynne playing Owney Madden and Frenchy DeMange. A chorus line of nearly naked colored girls ran out onto the stage and went into a routine never seen south of Central Park. Its big room, mahogany, brass and mirrors with a forty-foot bar, served as clubhouse for Trib reporters and editors.
Tables are covered with clean white cotton cloths and the waiters wear long white linen aprons that flap about their ankles. It took him back at one leap to the ambrosial nights of drinking and endless argument, when all philosophies had been probed and all the worlda€™s problems settled, that he had known in that homely place.
Why were there not more places like that in the world, he began to wondera€”places where a host was more than a shop-keeper, and men threw off their cares and talked and laughed openly together, without fear or suspicion, expanding cleanly and fruitfully in the glow of wine and fellowship? It drove me across town to East 39th, the wet streets dark and nearly deserted at that hour. Offering a fine view of all comings and goings, it became known as the Cohan Corner, where the great man was courted by theatrical types looking for work. A man at a nearby booth offered breadsticks, which were declined, and the group decamped to form a picket line in front of the hotel.
But the movie Woody saw there that night has lasted: The Thin Man, starring William Powell and Myrna Loy.
Ita€™s comical that the Nobel Committee gives its Peace Prize to do-gooders like Jane Addams. Ia€™d struggled through it in high school; they talked about Horace as if he were a mutual friend. So Woody dwells uncomfortably in a higher social and economic stratum of an increasingly disturbing world, as he takes stock of it when they return from their honeymoon. Fierce debate had started over his court-packing scheme, to circumvent the Supreme Courta€™s a€?nine old mena€? striking down one New Deal program after another. Frank of the Czechoslovak parliament, a German belonging to the half-Hitlerized Sudetendeutsche Partei, has said that the state must be a€?either a bridge between Germany and the southeast or a barricade against Germany.a€? . But when I walked into a jive joint with Diana, nobody took me for a rootietoot, let alone a lawyer. He had an about-town column in the Herald Tribune called a€?This New York.a€?

It was nearly empty at eleven in the morning, but even busy I couldna€™t have missed Walker halfway down the bar, next to an arresting sight: another man dressed, at that hour of the day, in white tie and tails.


I carried the briefcases when we got there, and Owneya€™s driver lugged the rest up to my apartment. After his death in 1942, a bronze plaque was installed to commemorate his tenure; it still hangs there today.
As the evening wore on and more and more people arrived, additional tables and chairs were brought out and placed on the dance floor until it almost disappeared. When I finally got a word in edgewise and asked what the hell, Basil shrugged off a€?two perfectly useless degreesa€? in classics from Yale and Oxford. Bradford, another Thin Man imitation, had come out while Diana was in Europe, but when she got back I took her to My Man Godfrey at Radio City.
Enlarging the Court had peoplea€™s backs up, while others felt the Court was so pre-Depression in make-up, it might as well be the Dark Ages. It was the New York of El Morocco by night, people with plenty of money despite the Depression, Broadway openings instead of bank closings, charity scavenger hunts instead of breadlines, uninterrupted self-indulgence instead of the dole. It was only two hundred years later that the physicist Charles made the first photographic impression, by projecting the outlines of one of his pupils on a white paper sheet impregnated with silver chloride. It was commercially introduced in 1839, a date generally accepted as the birth year of practical photography.The metal-based daguerreotype process soon had some competition from the paper-based calotype negative and salt print processes invented by Henry Fox Talbot.
And in 1839 Cornelius shot a self-portrait daguerrotype that some historians believe was the first modern photograph of a man ever produced.
Owney Madden grew up in the part of New York called Hella€™s Kitchen, and had been in the rackets since he was a kid, starting with one of its Irish gangs, The Gophers. He held a drink in one hand, a cigar in the other, and on the surface of the bar rested a silk top hat. I hung up my hat and coat, opened the briefcase Owney had given me and gazed at the money again, then stashed it in the back of my closet.
Then as I started thinking of him as a pudgy intellectual, he said something to Gene Tunney across the table about their boxing a few rounds at the Yale Club before coming to Cellaa€™s. He and drummer Gene Krupa were from his band, but the others were colored musicians, cool Teddy Wilson on piano and excited Lionel Hampton on vibes, the first mixed group wea€™d seen. He had to eat; and in all the world there are no steaks like the steaks Chris Cellini broils over an open fire with his own hands.

I loosened my tie, poured myself a stiff drink, and sat down beside a window a€” sat there a long time, the untasted drink in my hand, listening to it rain. Anyone whoa€™d box Gene Tunney for funa€” I gave up, and went and got another drink myself. Powell was a stockbroker down on his luck, plucked out of a hobo jungle to butler for the nuttiest family on Fifth Avenue.

Member Confrerie des Chevaliers du Tastevin, Wine & Food Society of America, Republican.
Nicephore Niepce (1765-1833) had the idea of using as sensitive material the bitumen, which is altered and made insoluble by light, thus keeping the images obtained unaltered.
Long before the first photographs were made, Chinese philosopher Mo Ti and Greek mathematicians Aristotle and Euclid described a pinhole camera in the 5th and 4th centuries BCE.
He communicated his experiences to Daguerre (1787-1851) who noticed that a iodide-covered silver plate - thedaguerreotype -, by exposition to iodine fumes, was impressed by the action of light action, and that the almost invisible alteration could be developed with the exposition to mercury fumes. In the 6th century CE, Byzantine mathematician Anthemius of Tralles used a type of camera obscura in his experimentsIbn al-Haytham (Alhazen) (965 in Basra a€“ c. Founded, with Cleon Throckmorton, Hoboken Theatrical Co., 1928, producing revivals of a€?After Dark,a€? a€?The Black Crook,a€? etc. It was then fixed with a solution of potassium cyanide, which dissolves the unaltered iodine.The daguerreotype (1839) was the first practical solution for the problem of photography. In 1841, Claudet discovered quickening substances, thanks to which exposing times were shortened. Guggenheim Fellow, League of Nations, Geneva, 1928-29, dir., Geneva office, League of Nations Assoc. More or less at the same time period, EnglishWilliam Henry Talbot substituted the steel daguerreotype with paper photographs (named calotype). Wilhelm Homberg described how light darkened some chemicals (photochemical effect) in 1694. Niepce of Saint-Victor (1805-1870), Nicephorea€™s cousin, invented the photographic glass plate covered with a layer of albumin, sensitized by silver iodide. The novel Giphantie (by the French Tiphaigne de la Roche, 1729a€“74) described what could be interpreted as photography.Around the year 1800, Thomas Wedgwood made the first known attempt to capture the image in a camera obscura by means of a light-sensitive substance.
Maddox and Benett, between 1871 and 1878, discovered the gelatine-bromide plate, as well as how to sensitize it. As with the bitumen process, the result appeared as a positive when it was suitably lit and viewed.
A strong hot solution of common salt served to stabilize or fix the image by removing the remaining silver iodide.
On 7 January 1839, this first complete practical photographic process was announced at a meeting of the French Academy of Sciences, and the news quickly spread. At first, all details of the process were withheld and specimens were shown only at Daguerre's studio, under his close supervision, to Academy members and other distinguished guests. Paper with a coating of silver iodide was exposed in the camera and developed into a translucent negative image. Unlike a daguerreotype, which could only be copied by rephotographing it with a camera, a calotype negative could be used to make a large number of positive prints by simple contact printing.
The calotype had yet another distinction compared to other early photographic processes, in that the finished product lacked fine clarity due to its translucent paper negative. This was seen as a positive attribute for portraits because it softened the appearance of the human face. Talbot patented this process,[20] which greatly limited its adoption, and spent many years pressing lawsuits against alleged infringers.
He attempted to enforce a very broad interpretation of his patent, earning himself the ill will of photographers who were using the related glass-based processes later introduced by other inventors, but he was eventually defeated. Nonetheless, Talbot's developed-out silver halide negative process is the basic technology used by chemical film cameras today. Hippolyte Bayard had also developed a method of photography but delayed announcing it, and so was not recognized as its inventor.In 1839, John Herschel made the first glass negative, but his process was difficult to reproduce. The new formula was sold by the Platinotype Company in London as Sulpho-Pyrogallol Developer.Nineteenth-century experimentation with photographic processes frequently became proprietary. This adaptation influenced the design of cameras for decades and is still found in use today in some professional cameras.
Petersburg, Russia studio Levitsky would first propose the idea to artificially light subjects in a studio setting using electric lighting along with daylight. In 1884 George Eastman, of Rochester, New York, developed dry gel on paper, or film, to replace the photographic plate so that a photographer no longer needed to carry boxes of plates and toxic chemicals around. Now anyone could take a photograph and leave the complex parts of the process to others, and photography became available for the mass-market in 1901 with the introduction of the Kodak Brownie.A practical means of color photography was sought from the very beginning. Results were demonstrated by Edmond Becquerel as early as 1848, but exposures lasting for hours or days were required and the captured colors were so light-sensitive they would only bear very brief inspection in dim light.The first durable color photograph was a set of three black-and-white photographs taken through red, green and blue color filters and shown superimposed by using three projectors with similar filters. It was taken by Thomas Sutton in 1861 for use in a lecture by the Scottish physicist James Clerk Maxwell, who had proposed the method in 1855.[27] The photographic emulsions then in use were insensitive to most of the spectrum, so the result was very imperfect and the demonstration was soon forgotten.
Maxwell's method is now most widely known through the early 20th century work of Sergei Prokudin-Gorskii.
Included were methods for viewing a set of three color-filtered black-and-white photographs in color without having to project them, and for using them to make full-color prints on paper.[28]The first widely used method of color photography was the Autochrome plate, commercially introduced in 1907. If the individual filter elements were small enough, the three primary colors would blend together in the eye and produce the same additive color synthesis as the filtered projection of three separate photographs.
Autochrome plates had an integral mosaic filter layer composed of millions of dyed potato starch grains. Reversal processing was used to develop each plate into a transparent positive that could be viewed directly or projected with an ordinary projector.
The mosaic filter layer absorbed about 90 percent of the light passing through, so a long exposure was required and a bright projection or viewing light was desirable.
Competing screen plate products soon appeared and film-based versions were eventually made. A complex processing operation produced complementary cyan, magenta and yellow dye images in those layers, resulting in a subtractive color image. Kirsch at the National Institute of Standards and Technology developed a binary digital version of an existing technology, the wirephoto drum scanner, so that alphanumeric characters, diagrams, photographs and other graphics could be transferred into digital computer memory. The lab was working on the Picturephone and on the development of semiconductor bubble memory. The essence of the design was the ability to transfer charge along the surface of a semiconductor.
