Live preview is a feature that allows a digital camera's display screen to be used as a viewfinder . This provides a means of previewing framing and other exposure before taking the photograph . In most such cameras, the preview is generated by means of continuously and directly projecting the image formed by the lens onto the main image sensor . This in turn feeds the electronic screen with the live preview image. The electronic screen can be either a liquid crystal display (LCD) or an electronic viewfinder (EVF) .

114-535: A focus peaking feature that highlights areas of the frame that are in focus. They are also in several ways more accurate than an optical viewfinder (OVF): Live preview has the following limitations: Live preview has been in use with bridge cameras for some years but with limited resolution and image quality. They are used in most mirrorless modern system cameras (e.g. Panasonic Micro Four Third System, Sony NEX, Sony SLT, Nikon V1). Many professional photographers and advanced amateurs prefer DSLR cameras that have
171-453: 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 By the end of the 1850s, the daguerreotype had been replaced by the less expensive and more easily viewed ambrotype and tintype , which made use of the recently introduced collodion process .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 paper soon became the preferred photographic method and held that position for many years, even after
228-868: A career out of taking pictures of "ghosts" or "spirits". There are many instances where people believe photos will bring bad luck either to the person taking the picture or people captured in the photo. For instance, a photograph taken of a pregnant woman will bring bad luck to the baby in the womb and photos taken of dead people will ensure that person is not successful in the afterlife. The production or distribution of certain types of photograph has been forbidden under modern laws, such as those of government buildings, highly classified regions, private property, copyrighted works, children's genitalia , child pornography and less commonly pornography overall. These laws vary greatly between jurisdictions. In some public property owned by government, such as law courts, government buildings, libraries, civic centres and some of
285-401: A contact-exposed copy of an engraving, was made in 1822 using the bitumen -based " heliography " process developed by Nicéphore Niépce . The first photographs of a real-world scene, made using a camera obscura , followed a few years later at Le Gras, France, in 1826, but Niépce's process was not sensitive enough to be practical for that application: a camera exposure lasting for hours or days
342-426: 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 . 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
399-580: A cultural advancement because of photography. People thrive off of the selfies of their favorite celebrities, many receive millions of likes on social media because of one simple selfie. Ideal photograph storage involves placing each photo in an individual folder constructed from buffered, or acid-free paper . Buffered paper folders are especially recommended in cases when a photograph was previously mounted onto poor quality material or using an adhesive that will lead to even more acid creation. Store photographs measuring 8x10 inches or smaller vertically along
456-669: A desired effect. The second is a more sophisticated type of live preview that displays the exact exposure 'look' on an electronic display and allows the photographer to alter the exposure look via adjustments to parameters such as shutter speed , film speed or ISO , and aperture , before the photograph is taken. This second type of live preview is the exposure simulation live preview type (or exposure priority display ). This type of live preview eliminates reliance on traditional light metering usage. Many modern bridge and compact cameras with movie mode have only an automatic exposure and limited exposure compensation control, and live view that
513-512: 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 7 January 1839, but working details were not made public until 19 August that year. Other inventors soon made drastic improvements that reduced
570-501: A live image to an electronic viewfinder in addition to the main rear screen for composition." The same technology was used by Olympus prior to Sony in the Olympus E-10 . Early examples of Exposure Simulation Live View (ES-LV) in advanced prosumer digicams with Full Manual / Manual ISO, such as Canon's PowerShot Pro70 (1998), Powershot G1 (2000) and Powershot Pro90 IS (2001), all feature an optical viewfinder or optical tunnel and display
627-468: 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 archivists do need to handle the actual photo, perhaps to examine the verso for writing, they can use gloves if there appears to be a risk from oils or dirt on the hands. Because daguerreotypes were rendered on a mirrored surface, many spiritualists also became practitioners of

#1732848220927684-535: A photograph via its 'exposure simulation' (ExpSim) enabled mode, or exposure priority display. This mode replaces the shortcomings of traditional estimation involved in the through-the-lens (TTL) metering techniques of the older framing type live view DSLRs with autogain/framing only, DSLRs without live view, as well as the shortcomings of optical viewfinders when ambient lighting becomes too low. Real-time exposure simulation live preview (or exposure priority display) had been available in many prosumer cameras, such as
741-590: A similar focus preview feature, plus first ever for any DSLR the new exposure simulation live view allowed capture of star exposures to selectable brightness 'effects' (Canon ExpSim LV). The first general-use interchangeable-lens DSLRs with live view for both exposure simulated live preview (ExpSim LV) and framing livepreview were the Canon 20Da of 2005, followed by Canon EOS 1Ds Mark III and Canon EOS 40D of 2007. The first general-use interchangeable-lens DSLR with live view for framing preview only like most fixed lens digicams
798-562: A small digital sensor. Mirrorless cameras feature a larger sensor and interchangeable lenses, like DSLRs, but sacrifice the SLR mirror mechanism and viewfinder to save size and cost, and hence only offer live preview. The SLT, developed by Sony , uses a mirror similar to that found in a DSLR. However, unlike the moving and fully reflective mirror of DSLRs, the SLT mirror is fixed and semi-reflective. New Zealand-based British photographer Gordon Laing describes
855-428: 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 light 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
912-399: A true optical through-the-lens viewfinder (OVF). Photograph A photograph (also known as a photo , image , or picture ) 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 now created using a smartphone or camera , which uses a lens to focus
969-466: Is almost as old as black-and-white , with early experiments including John Herschel 's Anthotype prints in 1842, the pioneering work of Louis Ducos du Hauron in the 1860s, and the Lippmann process unveiled in 1891, but for many years color photography remained little more than a laboratory curiosity. It first became a widespread commercial reality with the introduction of Autochrome plates in 1907, but
1026-414: Is different from Wikidata All article disambiguation pages All disambiguation pages Live preview The concept for cameras with live preview largely derives from electronic ( video ) TV cameras . Until 1995 most digital cameras did not have live preview, and it was more than ten years after this that the higher end digital single-lens reflex cameras (DSLR) adopted this feature, as it
1083-499: Is fundamentally incompatible with the swinging-mirror single-lens reflex mechanism. The first digital still camera with an LCD for autogain framing live preview was the Casio QV-10 in 1995. The first prosumer camera to use live view for both exposure simulation live preview ES-LV control and live preview framing was the fixed-lens Canon PowerShot G1 from 2000 (possibly the first was Canon Powershot Pro70 in 1998), although this
1140-464: Is not illegal to photograph a person who does not actively object. In South Africa photographing people in public is legal. Reproducing and selling photographs of people is legal for editorial and limited fair use commercial purposes. There exists no case law to define what the limits on commercial use are. In the United Kingdom there are no laws forbidding photography of private property from
1197-449: Is primarily for framing only. Live-preview-only cameras, that is cameras without an optical viewfinder , include four different categories: compact digital cameras , bridge digital cameras , and the newer mirrorless interchangeable lens cameras and Sony SLT cameras . Bridge cameras in general are higher-end, that is they contain more advanced features, better build quality, larger size, and are more expensive than compacts, but retain

#17328482209271254-560: 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. 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
1311-407: 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. Non-digital photographs are produced with a two-step chemical 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,
1368-501: The Canon PowerShot G series, before being available to in live view DSLRs. Some manufacturers of compact cameras, including prosumer models, still lack this exposure simulation live view feature, instead relying on the more rudimentary autogain/framing only live view, where slow focus and slow exposure estimation via TTL metering techniques are relied upon. Real-time exposure simulation capable live preview digital cameras make achieving

When interchangeable-lens DSLRs with STILLS only ExpSim LV (APS-C EOS 20Da, APS-H EOS 1DMkIII, Full Frame (FF) EOS 1DsMkIII), with its ExpSim LV having Full Manual / M/Auto-ISO mode and AE / M/Auto-ISO mode, ExpSim LV was extended for the first time in any interchangeable-lens DSLR to Canon's FF ExpSim LV (1080p) video in 5DMkIII, it
1482-809: The aperture selection was narrower than widest diameter (wide open). In Autogain framing live view, such as in AE modes with Auto ISO in effect, using the dof button can take on two different effects: autogain during aperture stopped down (easy to see dof preview), and autogain-locked or suspended during aperture stopped down (difficult to see dof, just like looking with a non-live view DSLR of optical viewfinder (OVF) preview through-the-lens (TTL). For ES-LV digicam users and ExpSim LV DSLR users, this advanced method of "Adjustable/Selectable Live Previewable Exposure Evaluation/Determination" shooting in Full Manual / M ISO mode completely eliminated light meter sensor reading TTL common from
1539-619: The appearance of the Canon EOS 7D , Nikon D300, Olympus E-3 and the Pentax K-7. Still more recently, the (upper) mid-range Nikon D7000 has brought the feature to a somewhat lower price point. Some real-time exposure simulated capable live preview digital cameras also offer live histogram graphs for tonal balance or color , where the graph changes instantaneously as exposure adjustments are made. Other features include live depth of field (DOF) preview, and live indication of overexposed areas of
1596-558: The desired exposures, especially in manual modes, more quickly available for both still and video photography. Among the DSLRs that do manage to focus using the standard phase-detection sensors used by DSLRs, unlike some compact digital cameras none has managed to show 100% frame coverage. This removes one of the key advantages of live preview over optical viewfinders, especially on more budget cameras. Additionally, 100% coverage optical viewfinders have recently become more common and affordable with

The time saved assessing instant optimal exposure choices for any new or changing lit scenario, freed
1710-423: The first camera to have live preview (product lines that did not exist when live preview came into use are not shown; as of August 2014, there is no product line in which live preview has been abandoned after being introduced): The principal function of live preview on Canon DSLRs from the 20Da onwards has been to allow, via LCD viewing, rapid acquisition of consistent and predictable exposure selection before taking
1767-802: The image Almost all modern bridge and compact cameras have a movie mode, while this feature only became available on DSLRs during 2008. The Nikon D90 with 720p video was announced in August 2008, and the Canon EOS 5D Mark II with 1080p video was announced in September 2008. The Canon EOS 5D Mark II was the first DSLR to offer full control over its real-time exposure simulation live preview for video, rather than just autogain/framing only live preview. Live preview can show additional information, such as an image histogram , focal ratio , camera settings, battery charge, and remaining storage space. Some implementations have

1824-415: 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 emulsion and the support material used, which was originally glass, then a variety of flexible plastic films , along with various types of paper for the final prints. Color photography
1881-406: The lighting conditions are too dark for an optical viewfinder. This type of live preview is the autogain/framing live view type (or framing priority display ). This requires traditional means of exposure determination requiring metering of the light coming through the lens, and interpreting the light intensity indication on an automatic light meter , and then adjusting exposure parameters for
1938-592: The longer edge of the photo in the buffered paper folder, within a larger archival box, and label each folder with relevant information to identify it. The rigid nature of the folder protects the photo from slumping or creasing, as long as the box is not packed too tightly or under filled. Folder larger photos or brittle photos stacked flat within archival boxes with other materials of comparable size. The most stable of plastics used in photo preservation, polyester , does not generate any harmful chemical elements, nor does it have any capability to absorb acids generated by
1995-508: The museums in Hong Kong, photography is not allowed without permission from the government. It is illegal to equip or take photographs and recording in a place of public entertainment, such as cinemas and indoor theaters. In Hungary, from 15 March 2014 when the long-awaited Civil Code was published, the law re-stated what had been normal practice, namely, that a person had the right to refuse being photographed. However, implied consent exists: it
2052-780: The negative is most commonly transferred (' printed ') onto photographic paper . Printing the negative onto transparent film stock is used to manufacture motion picture films. Alternatively, the film is processed to invert the negative image, yielding positive transparency . 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. 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
2109-474: The new art form. Spiritualists would claim that the human image on the mirrored surface was akin to looking into one's soul. The spiritualists also believed that it would open their souls and let demons in. Among some Muslims, it is makruh (disliked) to perform salah (worship) in a place decorated with photographs. Photography and darkroom anomalies and artifacts sometimes lead viewers to believe that spirits or demons have been captured in photos. Some have made
2166-504: The photograph itself. Polyester sleeves and encapsulation have been praised for their ability to protect the photograph from humidity and environmental 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
2223-406: 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
2280-424: 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. It is best to leave photographs lying flat on the table when viewing them. Do not pick it up from
2337-451: 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 Neu , the first easy-to-use color films of the modern multi-layer chromogenic type. These early processes produced transparencies for use in slide projectors and viewing devices, but color prints became increasingly popular after the introduction of chromogenic color print paper in

Each was a unique, opaque positive that could only be duplicated by copying it with
2508-406: The rise of digital prints . These prints are created from stored graphic formats such as JPEG , TIFF , and RAW . The types of printers used include inkjet printers , dye-sublimation printers , laser printers , and thermal printers . Inkjet prints are sometimes given the coined name " Giclée ". The Web has been a popular medium for storing and sharing photos ever since the first photograph
2565-469: 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 . The word photograph was coined in 1839 by Sir John Herschel and is based on the Greek φῶς ( phos ), meaning "light", and γραφή ( graphê ), meaning "drawing, writing", together meaning "drawing with light". The first permanent photograph,
2622-399: 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
2679-428: The subject that could be magnified for manual focusing purposes, although the preview was limited to a duration of thirty seconds. The first interchangeable-lens DSLR following ES-LV capabilities of Canon's Powershot G1 (maybe, Canon Powershot Pro70) was in early 2005 with the Canon EOS 20Da , a special version of the Canon EOS 20D with exposure simulation live view modifications for astrophotography , which included
2736-470: The technology: "[A] fixed semi-reflective mirror allows around 70% of the light to pass through to the sensor for full-time live view composition, but reflects the remaining 30% or so to the phase change AF system, allowing quick and continuous autofocusing in Live View and movie modes. 30% is however too little for a traditional optical viewfinder, so Sony doesn't bother, instead using the main sensor to deliver

Later, Canon extended its more sophisticated DSLR ExpSim LV all shooting light conditions like its Powershot digicams. The most significant advances and difference in DSLR version of ES-LV
2850-441: 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. The advent of the microcomputer and digital photography has led to
2907-614: Was only then, did use of OVF shifted over, more to the rear lcd monitor to shoot Cinematic (larger FF sensor frame than pro digital Super35mm and 35mm Cine cameras). The lesser Autogain Framing/Focus Live preview, borrowed from framing/focus autogain live view digicams, in lesser autogain live view DSLRs does not typically serve as their principal means of framing and previewing before taking a photograph, with this function still being mainly performed with optical viewfinder. The first interchangeable-lens DSLR to feature framing live preview

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
3078-507: Was simulating exposure changes effects with chosen aperture changes without stopping down the aperture. The ES-LV of its Powershot digicams always kept its apertures stopped down, so no 'aperture exposure simulation' was needed, and briefly opened aperture to assess focus with shutter button partially depressed before a shot is taken. The ExpSim LV of its EOS lens DSLRs could achieve the same 'exposure simulation' effect in both aperture stop-down mode and aperture wide open of its EOS lenses, even if
3135-536: Was still in the line of compact cameras. The first DSLR to use live view for framing preview only, like early other live view but non-mirrored digicams, was the fixed-lens Olympus E-10 from 2000. The first interchangeable-lens DSLR to use a live preview for framing was the Fujifilm FinePix S3 Pro , which was launched in October 2004. Its "Live Image" mode could display a live, black-and-white framing preview of
3192-454: Was the Olympus E-330 of 2006. There are two distinct modes of live-preview, with only a few manufacturers offering both in their digital cameras. The first is a more rudimentary type of live preview that displays the overall framing on an electronic display and allows a preview of what the camera's sensor will detect before the photograph is taken. This can be particularly helpful when
