[14] => [15] => [[File:View from the Window at Le Gras, Joseph Nicéphore Niépce, uncompressed UMN source.png|thumb|left|''[[View from the Window at Le Gras]]'', 1826 by [[Joseph Nicéphore Niépce]]]] [16] => [17] => After Niépce's death in 1833, Daguerre concentrated on [[silver halide]]-based alternatives. He exposed a silver-plated copper sheet to iodine vapor, creating a layer of light-sensitive [[silver iodide]]; exposed it in the camera for a few minutes; developed the resulting invisible [[latent image]] to visibility with mercury fumes; then bathed the plate in a hot salt solution to remove the remaining silver iodide, making the results light-fast. He named this first practical process for making photographs with a camera the [[daguerreotype]], after himself. Its existence was announced to the world on January 7, 1839 but working details were not made public until August 19 of the same year. Other inventors soon made drastic improvements which reduced the required amount of exposure time from a few minutes to just a few seconds, making portrait photography truly practical and widely popular during this time. [18] => [19] => The daguerreotype had shortcomings, notably the fragility of the mirror-like image surface and the particular viewing conditions required to see the image properly. Each was a unique opaque positive that could only be duplicated by copying it with a camera. Inventors set about working out improved processes that would be more practical. By the end of the 1850s the daguerreotype had been replaced by the less expensive and more easily viewed [[ambrotype]] and [[tintype]], which made use of the recently introduced [[collodion process]]. Glass plate collodion negatives used to make prints on [[Albumen print|albumen paper]] soon became the preferred photographic method and held that position for many years, even after the introduction of the more convenient [[gelatin process]] in 1871. Refinements of the gelatin process have remained the primary [[black-and-white]] photographic process to this day, differing primarily in the sensitivity of the [[photographic emulsion|emulsion]] and the support material used, which was originally glass, then a variety of [[film base|flexible plastic films]], along with various types of paper for the final prints.

It first became a widespread commercial reality with the introduction of [[Autochrome]] plates in 1907, but the plates were very expensive and not suitable for casual snapshot-taking with hand-held cameras. The mid-1930s saw the introduction of [[Kodachrome]] and [[Agfacolor|Agfacolor Neu]], the first easy-to-use color films of the modern multi-layer [[chromogenic]] type. These early processes produced transparencies for use in [[slide projector]]s and viewing devices, but color prints became increasingly popular after the introduction of chromogenic color print paper in the 1940s. The needs of the motion picture industry generated a number of special processes and systems, perhaps the best-known being the now-obsolete three-strip [[Technicolor]] process.

In the two-step process the light-sensitive film captures a ''negative'' image (colors and lights/darks are inverted). To produce a ''positive'' image, the negative is most commonly transferred ('[[Photographic printing|printed]]') onto [[photographic paper]]. Printing the negative onto transparent film stock is used to manufacture motion picture films. [27] => [28] => Alternatively, the film is processed to invert the ''negative'' image, yielding positive [[Transparency (photography)|transparencies]]. Such positive images are usually mounted in frames, called slides. Before recent advances in digital photography, transparencies were widely used by professionals because of their sharpness and accuracy of color rendition. Most photographs published in magazines were taken on color transparency film. [29] => [30] => Originally, all photographs were monochromatic or hand-painted in color. Although methods for developing color photos were available as early as 1861, they did not become widely available until the 1940s or 1950s, and even so, until the 1960s most photographs were taken in black and white. Since then, [[color photography]] has dominated popular photography, although black-and-white is still used, being easier to develop than color. [31] => [32] => [[Panoramic format]] images can be taken with cameras like the [[Hasselblad]] Xpan on standard film. Since the 1990s, panoramic photos have been available on the [[Advanced Photo System]] (APS) film. APS was developed by several of the major film manufacturers to provide a film with different formats and computerized options available, though APS panoramas were created using a mask in panorama-capable cameras, far less desirable than a true panoramic camera, which achieves its effect through a wider film format. APS has become less popular and has been discontinued. [33] => [34] => The advent of the [[microcomputer]] and [[digital photograph]]y has led to the rise of [[Digital printing|digital prints]]. These prints are created from stored [[Graphics file format|graphic formats]] such as [[JPEG]], [[TIFF]], and [[Raw image format|RAW]]. The types of printers used include [[inkjet printer]]s, [[dye-sublimation printer]], [[laser printer]]s, and [[thermal printer]]s. Inkjet prints are sometimes given the coined name "[[Giclée]]". [35] => [36] => The [[World Wide Web|Web]] has been a popular medium for storing and sharing photos ever since the first photograph was published on the web by [[Tim Berners-Lee]] in 1992 (an image of the [[CERN]] house band [[Les Horribles Cernettes]]). Today popular sites such as [[Flickr]], [[PhotoBucket]] and [[500px]] are used by millions of people to share their pictures.

Polyester sleeves and encapsulation have been praised for their ability to protect the photograph from [[humidity]] and environmental [[pollutants|pollution]], slowing the reaction between the item and the atmosphere. This is true, however the polyester just as frequently traps these elements next to the material it is intended to protect. This is especially risky in a storage environment that experiences drastic fluctuations in humidity or temperature, leading to ferrotyping, or sticking of the photograph to the plastic. Photographs sleeved or encapsulated in polyester cannot be stored vertically in boxes because they will slide down next to each other within the box, bending and folding, nor can the [[archivist]] write directly onto the polyester to identify the photograph. Therefore, it is necessary to either stack polyester protected photographs horizontally within a box, or bind them in a three ring binder. Stacking the photos horizontally within a flat box will greatly reduce ease of access, and binders leave three sides of the photo exposed to the effects of lightInternational Organization for Standardization. ISO 18902:2001(E). [[Geneva, Switzerland]]: [[International Organization for Standardization|ISO]] Office, 2007. and do not support the photograph evenly on both sides, leading to slumping and bending within the binder. The plastic used for enclosures has been manufactured to be as frictionless as possible to prevent scratching photos during insertion to the sleeves. Unfortunately, the slippery nature of the enclosure generates a build-up of [[static electricity]], which attracts [[dust]] and lint particles. The static can attract the dust to the inside of the sleeve, as well, where it can scratch the photograph. Likewise, these components that aid in insertion of the photo, referred to as slip agents, can break down and transfer from the plastic to the photograph, where they deposit as an oily film, attracting further lint and dust. At this time, there is no test to evaluate the long-term effects of these components on photographs. In addition, the plastic sleeves can develop kinks or creases in the surface, which will scratch away at the [[emulsion]] during handling. [47] => [48] => ===Handling and care=== [49] => It is best to leave photographs lying flat on the table when viewing them. Do not pick it up from a corner, or even from two sides and hold it at eye level. Every time the photograph bends, even a little, this can break down the [[emulsion]].Baggett, James L. "Handle with Care: Photos." Alabama Librarian. [50] => 54.1 (2004): 5. The very nature of enclosing a photograph in plastic encourages users to pick it up; users tend to handle plastic enclosed photographs less gently than non-enclosed photographs, simply because they feel the plastic enclosure makes the photo impervious to all mishandling. As long as a photo is in its folder, there is no need to touch it; simply remove the folder from the box, lay it flat on the table, and open the folder. If for some reason the researchers or [[archivist]]s do need to handle the actual photo, perhaps to examine the [[recto and verso|verso]] for writing, they can use gloves if there appears to be a risk from oils or dirt on the hands.

As photography is becoming such a common thing, these superstitions have drastically died down. People are no longer afraid of cameras and having their pictures taken because there are cameras practically everywhere; cell phones, security cameras, and X-rays are all pictures that are used to help us in today’s society. We know now that photographs are not scary, in fact, they are a great form of art and self-expression and can be used in several different ways that are beneficial. They can captivate many valuable memories and provide a sense of safety. A trip to a grocery store or gas station is less of a fearful activity because of security cameras. Thankfully we have the technology to view video feeds live. This would have been very helpful centuries ago because the process of actually taking a photo was very time-consuming and had to be under perfect conditions. Even then after the photo was taken, preserving it was a very difficult task without the equipment we have today.

Photograph

A photograph is an image created by light falling on a photosensitive surface, usually photographic film or an electronic image sensor, such as a CCD or a CMOS chip. Most photographs are created using a camera, which uses a lens to focus the scene's visible wavelengths of light into a reproduction of what the human eye would see.

About

Most photographs are created using a camera, which uses a lens to focus the scene's visible wavelengths of light into a reproduction of what the human eye would see. The process and practice of creating such images is called photography. Photographs are widely used for both personal and commercial purposes. They serve as visual records, capturing and preserving moments in time. They can be used to document events, tell stories, convey emotions, and communicate ideas. Photographs have played a crucial role in journalism, advertising, art, and scientific research. The history of photography dates back to the early 19th century, with the development of the camera obscura and the subsequent invention of the photographic process. The first permanent photograph was produced in 1826 by Joseph Nicéphore Niépce, although it took several more decades for photography to become accessible and widely used. Over the years, photography has undergone numerous technological advancements, leading to improved image quality, faster processing times, and the ability to capture and store images electronically. The digital revolution in the late 20th century transformed photography, ushering in an era of digital cameras, smartphones, and online image sharing platforms. Today, photographs are predominantly created and consumed digitally. They are displayed on screens, shared on social media platforms, and printed on a wide range of materials. With the rise of digital manipulation tools, photographs can be easily edited, retouched, and enhanced, blurring the line between reality and fiction. Photography as an art form has also gained recognition and appreciation. Many photographers use their skills and creativity to convey unique perspectives, evoke emotions, and explore various themes and concepts. Photographs can be found in galleries, museums, and exhibitions, alongside other visual arts. In conclusion, photographs are powerful visual representations that have become an integral part of our lives. They record our memories, convey information, and stir our emotions.
