Leica Q3 43
The Leica Q3 43 is a full-frame fixed-lens camera introduced in 2024 as a companion to the Leica Q3. It is Leica's first Q-series camera to feature an apochromatic lens. Specifications The Q3 43 has a stabilized 43 mm 2 Summicron APO lens with digital crop modes corresponding to 35 mm equivalent focal lengths of 60, 75, 90, and 120 mm. The Q3 43 features the same 60-megapixel CMOS full-frame sensor, measuring 36 x 24 mm, found in the original Q3. The Q3 43 is capable of 8K video recording at up to 30 frames per second and features phase-detection autofocus. The Q3 43's high resolution OLED electronic viewfinder has a resolution of 5.76 million dots. Lens For the first time in a Q-series camera, the Q3 43 has an apochromatically corrected lens, which Leica refers to by the designation APO. APO lenses have additional elements which aid in focusing light of different wavelengths, reducing chromatic and spherical aberration which results from different ...

Chromatic Aberration
In optics, chromatic aberration (CA), also called chromatic distortion, color aberration, color fringing, or purple fringing, is a failure of a lens to focus all colors to the same point. It is caused by dispersion: the refractive index of the lens elements varies with the wavelength of light. The refractive index of most transparent materials decreases with increasing wavelength. Since the focal length of a lens depends on the refractive index, this variation in refractive index affects focusing. Since the focal length of the lens varies with the color of the light different colors of light are brought to focus at different distances from the lens or with different levels of magnification. Chromatic aberration manifests itself as "fringes" of color along boundaries that separate dark and bright parts of the image. Types There are two types of chromatic aberration: ''axial'' (''longitudinal''), and ''transverse'' (''lateral''). Axial aberration occurs when different wavelengt ...

Point-and-shoot Cameras
A point-and-shoot camera, also known as a compact camera and sometimes abbreviated to P&S, is a still camera (either photographic film, film or digital camera, digital) designed primarily for simple operation. Most use focus free lenses or autofocus for Focus (optics), focusing, automatic systems for setting the Exposure (photography), exposure options, and have Flash (photography), flash units built in. They are popular for vernacular photography by people who do not consider themselves photographers but want easy-to-use cameras for Snapshot (photography), snapshots of vacations, parties, reunions and other events. Most compact digital cameras use small 1/2.3-type (“1/2.3-inch”) image sensors, but since 2008, a few non-interchangeable lens compact cameras use a List of large sensor fixed-lens cameras, larger sensor such as 1.0-type (“1-inch”), APS-C (e.g. Fujifilm X100 series), or even 35mm format, full frame (e.g. Sony Cyber-shot DSC-RX1, Sony RX1 series).

Ricoh GR III
The Ricoh GR is a digital large sensor compact camera announced by Ricoh on April 17, 2013, one of a number of Ricoh GR digital cameras. It was succeeded by the Ricoh GR II in 2015, the Ricoh GR III in 2019, and the GR IIIx in 2021. Ricoh GR Unlike its predecessors (the " GR Digital" series), the Ricoh GR incorporated an APS-C image sensor, while retaining a relatively compact form factor. Coupled with its retractable lens, the GR is potentially the slimmest of any camera in its class when powered off. Aside from portability, reviewers praised the GR for its lens quality and ergonomics. An unusual feature of the Ricoh GR was its built-in ND filter. Its maximum shutter speed was variable, depending on the aperture setting (ie, 1/4000s was only available at apertures smaller than 5.6). The Ricoh GR series has been compared against the Nikon Coolpix A and the Fujifilm X70, other large sensor compacts with the same fixed focal length (28mm). Ricoh GR II DPReview said that over ...

Fujifilm X100VI
The Fujifilm X100 is a series of digital compact cameras with a fixed prime lens. Originally part of the Fujifilm FinePix, FinePix line, then becoming a member of the Fujifilm X series, X series from Fujifilm, the X100 series includes the FinePix X100, X100S, X100T, X100F, X100V, and X100VI. They each have a large image sensor and a 23 mm lens (35 mm 35 mm equivalent focal length, equivalent angle of view in Full-frame digital SLR, full frame format). All six cameras have received generally positive reviews. The Fujifilm FinePix X100 was initially shown at the photokina 2010, Photokina show in September 2010 and was subsequently introduced in February 2011.

Sony RX1R
The Sony Cyber-shot DSC-RX1 is a series of premium fixed-lens full-frame digital compact cameras made by Sony as part of its Cyber-shot line. The DSC-RX1 was announced in September 2012. The DSC-RX1R, released in 2013, is a variant of the Sony DSC-RX1 without anti-aliasing filter in front of the image sensor. In 2015, both models were succeeded by the DSC-RX1R II. Cyber-shot DSC-RX1 The DSC-RX1 was the world's first fixed-lens, full-frame digital compact camera, and as of its announcement, was the world's smallest full-frame digital camera but is also considerably more expensive than most other compact cameras. It was announced in September 2012. Notable features The DSC-RX1 features a 35 mm f/2 Zeiss Sonnar lens with leaf shutter capable of a minimum shutter speed of 1/2000 s (for apertures 2.0 to 4.0), 1/3200 s (for apertures down to 5.6), and even 1/4000 s (for smaller apertures down to 22).

RAW File
A camera raw image file contains unprocessed or minimally processed data from the image sensor of either a digital camera, a motion picture film scanner, or other image scanner. Raw files are so named because they are not yet processed, and contain large amounts of potentially redundant data. Normally, the image is processed by a raw converter, in a wide-gamut internal color space where precise adjustments can be made before conversion to a viewable file format such as JPEG or PNG for storage, printing, or further manipulation. There are dozens of raw formats in use by different manufacturers of digital image capture equipment. Rationale Raw image files are sometimes described as "digital negatives". Like transparency film and unlike negative film, raw image pixels contain positive exposure measurements. The raw datasets are more like undeveloped film: a raw image can be developed by software in a non-reversible manner to reach a complete image that resolves every pix ...

Digital Negative
Digital Negative (DNG) is an Open format, open, lossless raw image format developed by Adobe Systems, Adobe and used for digital photography. It was launched on September 27, 2004. The launch was accompanied by the first version of the DNG specification,. plus various products, including a free-of-charge DNG converter utility. All Adobe photo manipulation software (such as Adobe Photoshop and Adobe Lightroom) released since the launch supports DNG.. DNG is based on the Tag Image File Format / Electronic Photography, TIFF/EP Open standard, standard format, and mandates significant use of metadata (computing), metadata. The specification of the file format is open and not subject to any intellectual property restrictions or patents.. Rationale for DNG Adobe states that, given the existence of a wide variety of camera-brand-specific raw image formats, it introduced DNG as a standardized and backward-compatible universal file format. It is based on the TIFF 6.0 standard. Various pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Film Photography
Film photography or classical photography, also known by the retronym analog photography, is a term usually applied to photography that uses chemical processes to capture an image, typically on paper, film or a hard plate. These processes were the only methods available to photographers for more than a century prior to the invention of digital photography, which uses electronic sensors to record images to digital media. Analog electronic photography was sometimes used in the late 20th century but soon died out. Photographic films utilize silver halide crystals suspended in emulsion, which when exposed to light record a latent image, which is then processed making it visible and insensitive to light. Despite a steep decline in popularity since the advent of digital photography, film photography has seen a limited resurgence due to social media and the ubiquity of digital cameras. With the renewed interest in traditional photography, new organizations (Film Is Not Dead, Lomogr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
