Blackmagic Cinema Camera
The Blackmagic Cinema Camera (often simply the Cinema Camera or BMCC) is a digital movie camera developed and manufactured by Blackmagic Design and released on September 4, 2012. It is part of the Cinema Camera family of digital movie cameras and shoots 2.5K video in raw, Apple ProRes, CinemaDNG and Avid DNxHD formats. History At the NAB Show in April 2012, Blackmagic Design announced and demonstrated the Cinema Camera and slated for its release on July with an initial price of US$2,995. However, in August, the release date was delayed for "final stages of Thunderbolt certification and internal testing". A passive Micro Four Thirds model was then announced at IBC in September for release in December, along with a collaboration with Arri for a set of kits exclusively for the camera. Alongside the announcement of the Pocket Cinema Camera and Production Camera 4K at NAB in April 2013, the price was dropped from its initial value to US$1,995 on August. It was then given an Arri PL ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Digital Movie Camera
A digital movie camera for digital cinematography is a video camera that captures footage digitally rather than the historically used movie camera, which shoots on film stock. Different digital movie cameras output a variety of different acquisition formats. Cameras designed for domestic use have also been used for some low-budget independent productions. Since the 2010s, digital movie cameras have become the dominant type of camera in the motion picture industry. Types Professional cameras There are a number of video cameras on the market designed specifically for high-end digital cinematography use. These cameras typically offer relatively large sensors, selectable frame rates, recording options with low compression ratios or in some cases with no compression, and the ability to use high-quality optics. Some of the cameras are expensive and some are only available to rent. Some of the most used professional digital movie cameras include: * Arri Alexa * Blackmagic URSA * ...

Dynamic Range
Dynamic range (abbreviated DR, DNR, or DYR) is the ratio between the largest and smallest values that a certain quantity can assume. It is often used in the context of signals, like sound and light. It is measured either as a ratio or as a base-10 ( decibel) or base-2 (doublings, bits or stops) logarithmic value of the difference between the smallest and largest signal values. Electronically reproduced audio and video is often processed to fit the original material with a wide dynamic range into a narrower recorded dynamic range that can more easily be stored and reproduced; this processing is called dynamic range compression. Human perception The human senses of sight and hearing have a relatively high dynamic range. However, a human cannot perform these feats of perception at both extremes of the scale at the same time. The human eye takes time to adjust to different light levels, and its dynamic range in a given scene is actually quite limited due to optical glare. The ins ...

Exposure Range
In photography, exposure range may refer to any of several types of dynamic range: * The '' light sensitivity range'' of photographic film, paper, or digital camera sensors. * The ''luminosity range'' of a scene being photographed. * The ''opacity range'' of developed film images * The ''reflectance range'' of images on photographic papers. The exposure range of a device is usually expressed in stops, which are equivalent to \log_ (c) where ''c'' is the medium or device's contrast ratio. For example, average Digital Video (DV) has a contrast ratio of 45:1, so its exposure range is roughly 5.5 stops. Film has an exposure range of approximately 14 stops. Exposure is usually controlled by changing the lens aperture (the amount of light it gathers), the shutter speed (how long light is gathered) or sensitivity (how strongly the film or sensor responds to light). Changing exposure does not change the exposure range. A graduated neutral density filter can be also used to improve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DaVinci Resolve
DaVinci Resolve (originally known as da Vinci Resolve) is a color grading, color correction, visual effects, and audio post-production video editing application for macOS, Windows, and Linux, originally developed by da Vinci Systems, and now developed by Blackmagic Design following its acquisition in 2009. In addition to the commercial version of the software (known as ''DaVinci Resolve Studio''), Blackmagic Design also distributes a free edition, with reduced functionality, simply named ''DaVinci Resolve'' (formerly known as ''DaVinci Resolve Lite''). Development Original da Vinci Systems development (2003–2009) The initial versions of DaVinci Resolve (known then as ''da Vinci Resolve'') were resolution-independent software tools developed by da Vinci Systems (based in Coral Springs, Florida), who had previously produced other color correction systems such as da Vinci Classic (1985), da Vinci Renaissance (1990), and da Vinci 2K (1998). The system was first announced in 200 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Zeiss AG
Carl Zeiss AG (), branded as ZEISS, is a German manufacturer of optical systems and optoelectronics, founded in Jena, Germany in 1846 by optician Carl Zeiss. Together with Ernst Abbe (joined 1866) and Otto Schott (joined 1884) he laid the foundation for today's multi-national company. The current company emerged from a reunification of Carl Zeiss companies in East and West Germany with a consolidation phase in the 1990s. ZEISS is active in four business segments with approximately equal revenue (Industrial Quality and Research, Medical Technology, Consumer Markets and Semiconductor Manufacturing Technology) in almost 50 countries, has 30 production sites and around 25 development sites worldwide. Carl Zeiss AG is the holding of all subsidiaries within Zeiss Group, of which Carl Zeiss Meditec AG is the only one that is traded at the stock market. Carl Zeiss AG is owned by the foundation Carl-Zeiss-Stiftung. The Zeiss Group has its headquarters in southern Germany, in the smal ...

Neutral-density Filter
In photography and optics, a neutral-density filter, or ND filter, is a filter that reduces or modifies the intensity of all wavelengths, or colors, of light equally, giving no changes in hue of color rendition. It can be a colorless (clear) or grey filter, and is denoted by Wratten number 96. The purpose of a standard photographic neutral-density filter is to reduce the amount of light entering the lens. Doing so allows the photographer to select combinations of aperture, exposure time and sensor sensitivity that would otherwise produce overexposed pictures. This is done to achieve effects such as a shallower depth of field or motion blur of a subject in a wider range of situations and atmospheric conditions. For example, one might wish to photograph a waterfall at a slow shutter speed to create a deliberate motion-blur effect. The photographer might determine that to obtain the desired effect, a shutter speed of ten seconds was needed. On a very bright day, there might be s ...

Lossless Compression
Lossless compression is a class of data compression that allows the original data to be perfectly reconstructed from the compressed data with no loss of information. Lossless compression is possible because most real-world data exhibits statistical redundancy. By contrast, lossy compression permits reconstruction only of an approximation of the original data, though usually with greatly improved compression rates (and therefore reduced media sizes). By operation of the pigeonhole principle, no lossless compression algorithm can efficiently compress all possible data. For this reason, many different algorithms exist that are designed either with a specific type of input data in mind or with specific assumptions about what kinds of redundancy the uncompressed data are likely to contain. Therefore, compression ratios tend to be stronger on human- and machine-readable documents and code in comparison to entropic binary data (random bytes). Lossless data compression is used in many ...

Solid-state Drive
A solid-state drive (SSD) is a solid-state storage device that uses integrated circuit assemblies to store data persistently, typically using flash memory, and functioning as secondary storage in the hierarchy of computer storage. It is also sometimes called a semiconductor storage device, a solid-state device or a solid-state disk, even though SSDs lack the physical spinning disks and movable read–write heads used in hard disk drives (HDDs) and floppy disks. SSD also has rich internal parallelism for data processing. In comparison to hard disk drives and similar electromechanical media which use moving parts, SSDs are typically more resistant to physical shock, run silently, and have higher input/output rates and lower latency. SSDs store data in semiconductor cells. cells can contain between 1 and 4 bits of data. SSD storage devices vary in their properties according to the number of bits stored in each cell, with single-bit cells ("Single Level Cells" or "SLC ...

Patch (computing)
A patch is a set of changes to a computer program or its supporting data designed to update, fix, or improve it. This includes fixing security vulnerabilities and other bugs, with such patches usually being called bugfixes or bug fixes. Patches are often written to improve the functionality, usability, or performance of a program. The majority of patches are provided by software vendors for operating system and application updates. Patches may be installed either under programmed control or by a human programmer using an editing tool or a debugger. They may be applied to program files on a storage device, or in computer memory. Patches may be permanent (until patched again) or temporary. Patching makes possible the modification of compiled and machine language object programs when the source code is unavailable. This demands a thorough understanding of the inner workings of the object code by the person creating the patch, which is difficult without close study of the sourc ...

Arri
The Arri Group () is a German manufacturer of motion picture film equipment. Based in Munich, the company was founded in 1917. It produces professional motion picture cameras, lenses, lighting and post-production equipment. Hermann Simon mentioned this company in his book ''Hidden Champions of the 21st Century'' as an example of a " hidden champion". The Arri Alexa camera system was used to film Academy Award winners for Best Cinematography including ''Hugo'', ''Life of Pi'', ''Gravity'', '' Birdman'', '' The Revenant'' and '' 1917''. History Early history Arri was founded in Munich, Germany on 12 September 1917 by August Arnold and Robert Richter as Arnold & Richter Cine Technik. The acronym ''Arri'' was derived from the initial two letters of the founders' surnames, ''Ar''nold and ''Ri''chter. In 1924, Arnold and Richter developed their first film camera, the small and portable Kinarri 35. In 1937, Arri introduced the world's first reflex mirror shutter in the Arriflex 35 c ...
