EasyHDR is a High Dynamic Range (HDR) image processing software that merges differently exposed photographs into HDR radiance map and tone maps them. With a single photograph, easyHDR can be used to increase contrast and refresh colors (LDR enhancement mode).
EasyHDR is designed for use under macOS [1] and Microsoft Windows. It works on Linux under Wine.
Via dcraw and LibRaw, easyHDR supports the handling of raw image files. Lens correction (distortion and chromatic aberration) is addressed based on the LensFun database.
EasyHDR allows for batch processing. To this end, the user may save custom presets for tone mapping.
The functionality of easyHDR with respect to HDR image processing includes:
In case of a single low-dynamic-range (LDR) photograph, which often is missing details in highlights or shadows, the tone mapping of easyHDR may be used to increase contrast and refresh colors. This is in particular the case when developing raw images. [2] [3]
EasyHDR is shipped with a plug-in for Adobe Lightroom that allows exporting photos (original or pre-processed) from Lightroom to easyHDR for processing and finally storing the output results into the Lightroom catalog. [4]
EasyHDR was developed by Bartłomiej Okonek in 2006, then studying at Wrocław University of Science and Technology, Poland, in particular for use in astrophotography.
The HDR generation and tone mapping algorithm is also used by FARO Scene LT point cloud viewing software. [5]
Adobe Photoshop is a raster graphics editor developed and published by Adobe for Windows and macOS. It was created in 1987 by Thomas and John Knoll. It is the most used tool for professional digital art, especially in raster graphics editing, and its name has become genericised as a verb although Adobe disapproves of such use.
In photography and videography, multi-exposure HDR capture is a technique that creates high dynamic range (HDR) images by taking and combining multiple exposures of the same subject matter at different exposures. Combining multiple images in this way results in an image with a greater dynamic range than what would be possible by taking one single image. The technique can also be used to capture video by taking and combining multiple exposures for each frame of the video. The term "HDR" is used frequently to refer to the process of creating HDR images from multiple exposures. Many smartphones have an automated HDR feature that relies on computational imaging techniques to capture and combine multiple exposures.
High-dynamic-range rendering, also known as high-dynamic-range lighting, is the rendering of computer graphics scenes by using lighting calculations done in high dynamic range (HDR). This allows preservation of details that may be lost due to limiting contrast ratios. Video games and computer-generated movies and special effects benefit from this as it creates more realistic scenes than with more simplistic lighting models. HDRR was originally required to tone map the rendered image onto Standard Dynamic Range (SDR) displays, as the first HDR capable displays did not arrive until the 2010s. However if a modern HDR display is available, it is possible to instead display the HDRR with even greater contrast and realism.
Tone mapping is a technique used in image processing and computer graphics to map one set of colors to another to approximate the appearance of high-dynamic-range (HDR) images in a medium that has a more limited dynamic range. Print-outs, CRT or LCD monitors, and projectors all have a limited dynamic range that is inadequate to reproduce the full range of light intensities present in natural scenes. Tone mapping addresses the problem of strong contrast reduction from the scene radiance to the displayable range while preserving the image details and color appearance important to appreciate the original scene content.
Digital "darkroom" is the hardware, software and techniques used in digital photography that replace the darkroom equivalents, such as enlarging, cropping, dodging and burning, as well as processes that do not have a film equivalent.
Aperture is a discontinued professional image organizer and editor developed by Apple between 2005 and 2015 for the Mac, as a professional alternative to iPhoto.
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.
Adobe Photoshop Lightroom, usually called Lightroom, is an image organization and processing application developed by Adobe. It is licensed as a standalone subscription or as part of Creative Cloud. It is supported on Windows, macOS, iOS, Android, and tvOS. Its primary uses include importing, saving, viewing, organizing, tagging, editing, and sharing large numbers of digital images. Lightroom's editing functions include white balance, presence, tone, tone curve, HSL, color grading, detail, lens corrections, and calibration manipulation, as well as transformation, spot removal, red eye correction, graduated filters, radial filters, and adjustment brushing. The name Lightroom is a play on the darkrooms used for processing film.
In digital photography, exposing to the right (ETTR) is the technique of adjusting the exposure of an image as high as possible at base ISO to collect the maximum amount of light and thus get the optimum performance out of the digital image sensor.
Portrait Professional or PortraitPro is a portrait photography retouching software developed by Anthropics Technology and initially released in 2006. It automates the photo editing process with algorithms that manipulate facial features, remove skin imperfections, alter colors and tone, replace the background, and so on. It is available as a standalone application, as well as Adobe Photoshop, Lightroom, Photoshop Elements, and Aperture plug-ins on Windows and OS X systems.
RawTherapee is a free and open source application for processing photographs in raw image formats such as those created by many digital cameras. It comprises a subset of image editing operations specifically aimed at non-destructive post-production of raw photos and is primarily focused on improving a photographer's workflow by facilitating the handling of large numbers of images. It is notable for the advanced control it gives the user over the demosaicing and developing process. It is cross-platform, with versions for Microsoft Windows, macOS and Linux.
SilverFast is the name of a family of software for image scanning and processing, including photos, documents and slides, developed by LaserSoft Imaging.
Darktable is a free and open-source photography application and raw developer. Rather than being a raster graphics editor like Adobe Photoshop or GIMP, it comprises a subset of image editing operations specifically aimed at non-destructive raw image post-production. It is primarily focused on improving a photographer's workflow by facilitating the handling of large numbers of images. It is freely available in versions tailored for most major Linux distributions, macOS, Solaris and Windows and is released under the GPL-3.0-or-later.
Luminance HDR, formerly Qtpfsgui, is graphics software used for the creation and manipulation of high-dynamic-range images. Released under the terms of the GPL, it is available for Linux, Windows and Mac OS X. Luminance HDR supports several High Dynamic Range (HDR) as well as Low Dynamic Range (LDR) file formats.
Pixel Camera is a camera phone application developed by Google for the Android operating system on Google Pixel devices. Development with zoom lenses for the application began in 2011 at the Google X research incubator led by Marc Levoy, which was developing image fusion technology for Google Glass. It was publicly released for Android 4.4+ on the Google Play on April 16, 2014. The app was initially released as Google Camera and supported on all devices running Android 4.4 KitKat and higher. However, in October 2023, coinciding with the release of the Pixel 8 series, it was renamed to Pixel Camera and became officially supported only on Google Pixel devices.
Noiseless is an image noise reduction application by Macphun Software. The application is designed to reduce the noise found in digital photographs. The noise is often a result of snapping pictures in low light environments.
