Fotos Sem Photoshop

Adobe Photoshop é um software caracterizado como editor de imagens bidimensionais do tipo raster (possuindo ainda algumas capacidades de edição típicas dos editores vectoriais) desenvolvido pela Adobe Systems. É considerado o líder no mercado dos editores de imagem profissionais, assim como o programa de facto para edição profissional de imagens digitais e trabalhos de pré-impressão.
Sua mais recente versão é apelidada como Adobe Photoshop CS5 (sigla cujo significado é Creative Suite 5, correspondente à décima segunda edição desde seu lançamento), disponível para os sistemas operativos Microsoft Windows e Mac OS X. Pode ser rodado também no Linux, através da camada de compatibilidade Wine. Algumas versões anteriores foram lançadas também para IRIX, mas o suporte a esta versão foi descontinuado após a versão 3.0.
Bem, nas fotos abaixo esse programa não foi usado, acredita???

Early history if photoshop (useful info)
In 1987, Thomas Knoll, a PhD student at the University of Michigan, began writing a program on his Macintosh Plus to display grayscale images on a monochrome display. This program, called Display, caught the attention of his brother John Knoll, an Industrial Light & Magic employee, who recommended Thomas turn it into a full-fledged image editing program. Thomas took a six month break from his studies in 1988 to collaborate with his brother on the program, which had been renamed ImagePro.[1] Later that year, Thomas renamed his program Photoshop and worked out a short-term deal with scanner manufacturer Barneyscan to distribute copies of the program with a slide scanner; a “total of about 200 copies of Photoshop were shipped” this way.[2]
During this time, John traveled to Silicon Valley and gave a demonstration of the program to engineers at Apple and Russell Brown, art director at Adobe. Both showings were successful, and Adobe decided to purchase the license to distribute in September 1988.[1] While John worked on plug-ins in California, Thomas remained in Ann Arbor writing program code. Photoshop 1.0 was released in 1990 for Macintosh exclusively
High-speed camera
A high speed camera is a device used for recording fast moving objects as a photographic image(s) onto a storage media. After recording, the images stored on the media can be played back in slow-motion. Early high speed cameras used film to record the high speed events but today, high speed cameras are entirely electronic using either a charge-coupled device (CCD) or a CMOS image sensor, recording typically over 1000 frames per second into DRAM and playing slowly images back to study the motion for scientific study of transient phenomena.[1] A high speed camera can be classified as (1) a high speed film camera that records to film, (2) a high speed framing camera that records a short burst of images to film/digital still camera, a high speed streak camera that records to film/digital memory or (3) a high speed video camera recording to digital memory.
A normal motion picture is filmed and played back at 24 frames per second, while television uses 25 frames/s (PAL) or 29.97 frames/s (NTSC). High speed cameras can film up to a quarter of a million frames per second by running the film over a rotating prism or mirror instead of using a shutter, thus reducing the need for stopping and starting the film behind a shutter which would tear the film stock at such speeds. Using this technique one can stretch one second to more than ten minutes of playback time (super slow motion). The fastest cameras are generally in use in scientific research, military test and evaluation, and industry. An example of an industrial application is crash testing to better document the crash and what happens to the automobile and passengers during a crash. Today, the digital high speed camera has replaced the film camera used for Vehicle Impact Testing [2]. Television series such as MythBusters and Time Warp often use high speed cameras to show their tests in slow motion. The fastest high speed camera has the ability to take pictures at a speed of 200 million frames per second.[3]
A problem for high speed cameras is the needed exposure for the film, so one needs very bright light to be able to film at forty thousand frames per second sometimes leading to the subject of examination being destroyed because of the heat of the lighting.
Even higher speed imaging is possible using specialized electronic charge-coupled device (CCD) imaging systems which can achieve speeds of up to or in excess of 25 million frames per second. All development in high speed cameras is now focused on digital video cameras which have many operational and cost benefits over film cameras.
Recent advances in the form of image converter devices are able to provide temporal resolutions of less than fifty picoseconds, equivalent to over 20,000,000,000 (twenty billion) frames per second.[citation needed] These instruments operate by converting the incident light (consisting of photons) into a stream of electrons which are then deflected onto a photoanode, back into photons, which can then be recorded onto either film or CCD.
Photography is the process, activity and art of creating still or moving pictures by recording radiation on a radiation-sensitive medium, such as a photographic film, or an electronic sensor. Light patterns reflected or emitted from objects activate a sensitive chemical or electronic sensor during a timed exposure, usually through a photographic lens in a device known as a camera that also stores the resulting information chemically or electronically. Photography has many uses for business, science, art, and pleasure.
