The Photographic Revolution Back in 1877 a 23 -Year-Old Bank Clerk, George Eastman, Took up Photography As a Hobby
the photographic revolution Back in 1877 a 23 -year-old bank clerk, George Eastman, took up photography as a hobby. Like all picturetakers of his time, he carried a huge camera and tripod, chemicals, a tent for a darkroom, and other equipment. He had to make a "wet plate" by coating a light-sensitive emulsion on a piece of glass immediately before he exposed it. Picturetaking at that time was hard work, but Eastman felt it could be made easier and more fun. After many experiments in his mother's kitchen, he found a way to mass- produce photographic dry plates, and in 1880 he started to make them com mercially in a rented loft in the downtown section of Rochester, N. Y . In 1884 Eastman introduced a paper-base "film," and in 1888, the No.1 Kodak Camera - the small box camera which simplified photography so that anyone could take pictures. Eastman himself coined the trademark "Kodak" and the famous advertising slogan "You press the button, we do the rest." The Kodak camera caught on quickly, and the company sold over 100,000 of them in the first eight years. Today, some 52 million Americans take more Picturetaking in the days before Kodak cameras. than two billion snapshots each year. Picture taking has become America's number- one hobby. 2 © 1962 Eastman Kodak Company -I.. .. 1 I ~ , The No. 1 Kodak The first Folding New styling was fea· The popular Brownie Camera of 1888 sim· Brownie Camera was tured in Baby Brown Starflash Camera was plified photography. offered in 1904. -
My Mother's Camera
Manning 1 Pam Manning Marydorsey Wanless Retro Camera Seminar AR399 F April 10, 2011 My Mother’s Camera The Kodak Brownie camera has a long history with the Eastman Kodak company which began in February 1900 with the introduction of a very basic cardboard box camera with a simple lens that took 2¼ inch square pictures and cost only $1. The Brownie introduced the concept of snapshot photography and was intended to introduce photography to everyone, not just professional photographers (Kodak). What is considered one of the greatest slogans in advertising history, “You push the button, we do the rest” reinforced the simplicity of the Brownie camera (American Heritage). Designed and marketed for children, the Brownie camera was named after popular characters created by Palmer Cox, a children’s author and illustrator. Cox was the Walt Disney of his day. His Brownie characters were as well known in the 1880’s as Mickey Mouse is today (Kodak). Like Disney’s characters, Cox’s Brownies often appeared in ads. They helped sell everything from candies to cigars, coffee to ice cream, and even painkillers. Brownie dolls, games, puzzles, and trading cards were eagerly sought. And so was the Brownie camera, far beyond anyone’s expectations (Kodak). My history with the Kodak Brownie began when my mother took my picture with her Kodak Brownie Hawkeye. She would direct me to stand in a certain pose or perform a certain task. When she was happy with what she saw she would then back away from me, hold the camera about waist height, look down into the viewfinder and click. -
Transient Luminous Events Observed with the Pinhole Camera from Sierra Negra Volcano in Mexico
International Journal of Modern Research in Engineering and Technology (IJMRET) www.ijmret.org Volume 4 Issue 1 ǁ January 2019. Transient Luminous Events observed with the pinhole camera from Sierra Negra Volcano in Mexico E. Ponce1, S. Hernandez1, H. Salazar1, O. Martinez1, R. Conde1. 1(Department of physics and Mathematics, Autonomous University of Puebla, Mexico) ABSTRACT: The next generation of experiments devoted to study extreme energy cosmic rays will be at space platforms. Recent satellite missions have shown that the UV light background is more complex than previous models. Therefore, the observation of transient luminous events TLEs at the upper atmosphere will be important, information about the time and space evolution of this very fast events may need to be recorded, this impose requirements of a wide field of view and the largest focus depth. The simplest optical design, a pinhole camera fulfills these characteristics. This pinhole camera have a multi anode photomultiplier, eight by eight pixels, that allow us to register 2d images of TLEs of about milliseconds. In this work, we present the observations of some events recorded from Sierra Negra Volcano in Mexico and its capabilities in order to use it as a monitoring device.

Though upside-down and reversed, these projections were immediately recognized by 16th and 17th century draftsmen and artists as useful in creating more accurate representations of the world. The camera obscura also led to the birth of photography as it aided experimenters in their attempts to record an image onto a chemically sensitized surface. Even the mechanical photographic camera owes its basic structural design the camera obscura. Though developments in technology have made its use obsolete in the image-making process, a revival of similar devices has occurred throughout the 20th century. Lens-less, or pinhole, cameras were utilized by Pictorialist photographers who were interested in using its abilities to create soft focused, painterly-like images. And pinhole cameras continue to appeal to amateur, professional and fine art photographers as both an exciting novelty and a serious pursuit in artistic expression. DESCRIPTION : This studio course introduces the student to a variety of lens-less camera building techniques and photographic pinhole aesthetics. The course will discuss the uses of lens-less photography in historical and contemporary contexts. Students will be expected to work diligently during class hours. Each assignment will build upon the previous so it is crucial that the student attend each class session. The course will begin with a simple matchbox camera and advance to telephoto, wide-angle, panoramic and digital pinhole cameras. -

Below is a glossary of CCTV terms to help you discuss your surveillance system needs with your sales representative. Terms Aperture Aperture is the area of the camera lens that gathers light. The iris of the CCTV lens controls the size of aperture. Auto Iris Auto iris lenses adjust for changing light conditions in a camera view. If the sun shines on a camera with an auto iris lens, the lens will adjust the amount of light so the picture remains clear. BNC A type of coaxial cable connector that consists of a pin and a spring loaded locking mechanism. Commonly used for secure termination of CCTV cabling and cameras. Box Camera A common type of camera that has rectangular shape. Box cameras often have interchangeable lenses and offer a versatile platform for a variety of applications. CCD Charge Coupled Device - a light sensitive imaging device for almost all cameras. Typical sizes for CCTV cameras: 1/2”, 1/3”& 1/4”. C Mount Type of screw-on mounting for CCTV camera lenses. C mount lenses need an adapter ring when used with CS mount cameras (see CS Mount). Coaxial Cable (COAX) Coaxial cable is a cable type that has a signal wire surrounded by a protective braided shield commonly used connect cameras back to the DVR. Compression Compression techniques are used in digital CCTV to reduce the file sizes of recorded video images. -
The Development and Growth of British Photographic Manufacturing and Retailing 1839-1914
The development and growth of British photographic manufacturing and retailing 1839-1914 Michael Pritchard Submitted for the degree of Doctor of Philosophy Department of Imaging and Communication Design Faculty of Art and Design De Montfort University Leicester, UK March 2010 Abstract This study presents a new perspective on British photography through an examination of the manufacturing and retailing of photographic equipment and sensitised materials between 1839 and 1914. This is contextualised around the demand for photography from studio photographers, amateurs and the snapshotter. It notes that an understanding of the photographic image cannot be achieved without this as it directly affected how, why and by whom photographs were made. Individual chapters examine how the manufacturing and retailing of photographic goods was initiated by philosophical instrument makers, opticians and chemists from 1839 to the early 1850s; the growth of specialised photographic manufacturers and retailers; and the dramatic expansion in their number in response to the demands of a mass market for photography from the late1870s. The research discusses the role of technological change within photography and the size of the market. It identifies the late 1880s to early 1900s as the key period when new methods of marketing and retailing photographic goods were introduced to target growing numbers of snapshotters. Particular attention is paid to the role of Kodak in Britain from 1885 as a manufacturer and retailer. A substantial body of newly discovered data is presented in a chronological narrative. In the absence of any substantive prior work this thesis adopts an empirical approach firmly rooted in the photographic periodicals and primary sources of the period. -
GALEX: the Galaxy Evolution Explorer
National Aeronautics and Space Administration GALEX Galaxy Evolution Explorer This image of the Southern Pinwheel Galaxy, or M83, was taken in ultraviolet light by the Galaxy Evolution Explorer. Ultraviolet light traces populations of young stars. The image shows that new stars are forming at up to 140,000 light-years from the center of the galaxy. Taken at scheduled intervals between March 15 and May 20, 2007, this is one of the longest exposure images ever made of a nearby galaxy (at 15 million light-years away).

Introduction to Single Lens Reflex Cameras
Introduction to SLR Cameras by Mr. KUMON : 01 Page 1 of 13 - Introduction to Single Lens Reflex Cameras - Part 1 : What is an SLR camera ? Though SLR cameras are common around the world, they have a rather prestigious image — they are perceived as "high-class" and thought to be used by only professional photographers. The reasons for these presumptions, however, are not widely understood. Let's discuss the logic of this reasoning by examining the history of photography and the mechanisms of cameras. And you can tell how convenient today's photography system are by comparing it to a pinhole picture taken with an SLR camera. Written by KUMON, Yasushi 1. A Brief History of Photography 1.1.

What is an SLR Camera ? 1. A Brief History of Photography 1.1. Camera Obscura The word "camera" is derived from the Latin "camera obscura." In Latin, "camera" means "room", and "obscura" means "dark." "Photo 0" illustrates the principle of camera obscura. Light enters a darkened room through a small hole, and the image of an object outside the room appears on the wall opposite the hole. This is the same principle at work in so-called pin-hole cameras. -

Nature of the UV atmospheric transient events is not known yet and more experimental data on them are needed. Study of space-time development of UV transient events is suggested with the help of a new fast imaging detector: pinhole camera with the multi anode photomultiplier tube. Design and construction of the pinhole camera to be installed at the satellite is presented. The camera mountain testing and calibration are suggested.

10.1515/nor-2016-0005 Nordicom Review 37 (2016) 1, pp. 15-27 Aporetic Apparatus Epistemological Transformations of the Camera Janne Seppänen & Juha Herkman Abstract In this article, we examine the epistemology of the camera today. In order to answer this question, we concentrate on three social and technological forms: the camera obscura, the photographic camera, and the digital camera. On the one hand, the camera extends our human sensibilities and helps us to obtain knowledge of the world. On the other hand, it works as a device for delusion, bodily vision and spectacle. Historically, these two functions are meshed together in complicated ways and this establishes the paradoxical epistemology of the camera. We argue that, even if contemporary debates about the truthfulness of the photographic image have persistently been tied to the digitisation of the photographic process, the very origin of these debates actually lies in the camera itself and its contradictory epistemology. The camera has worked, and still works, as an apparatus that relentlessly produces irresolv- able ambiguity, aporia, between true knowledge and illusory vision. Keywords: camera, camera obscura, epistemology, photography, digital photography, vis- ual culture Introduction With the proliferation of digital cameras, and particularly camera phones, almost every situation and event can now be photographed and quickly placed on public display. Camera images are thus an essential part of communication and surveillance, in both public and private spheres, as well as, in fact, the whole visual constitution of society. The camera also seems to be an idea or a representation, which has gained a signifi- cant presence in the narratives of popular cinema and television.
