![]() The manufacturers’ software is intended for handling images from a specific camera, whereas the open-source projects try to cover as wide a range of cameras and formats as possible. This is where both specific proprietary software provided by the camera manufacturer, as well as much-wider-ranging open-source software such as UFRaw and DCRaw come into play. And they need to be converted before they can really be used. Because of the lack of standardization and the wide universe of different cameras on the market, these files are more complex to work with than standard formats like JPEG. The data varies depending on the camera model and manufacturer. There are many raw file formats, from CR2, to SR2, to K25. These are files containing largely-unprocessed data directly from image sensor of a camera or scanner. ![]() On Windows systems, ImageMagick delegates to DCraw. Although it natively handles a wide range of standard image files, such as JPEG and PNG, when it needs to handle raw camera files, it delegates the conversion of these files to other command-line utilities that are included in the ImageMagick installation. ImageMagick itself also delegates to other open-source programs when it needs to handle certain types of files. Because it is open-source and has these command-line utilities, it has ended up being widely used in other open-source projects that need to handle images programmatically. These command-line utilities are very powerful and can be used to programmatically edit and convert images, such as photographs, and even to programmatically create new images, such as procedurally-generated slates for video projects. It has both a graphical user interface as well as command-line utilities. It was first created in 1987 and has been maintained and developed since then. ImageMagick is open-source software for running a wide range of operations on images. Or should that idiom be 'blows the pixels off the print'? With algorithms by Jacques, the same developer who gave us CIECAM02, it can both mimic a film darkroom while still providing all the quirky effects my hidden artist will learn to love.This article provides instructions on how to improve ImageMagick’s handling of raw images by changing the open-source utilities that ImageMagick uses by default ( UFraw on Linux and DCraw in Windows) to other utilities. The big news in RawTherapee is a Black and White tool kit that 'blows the pants off' every other image editor out there. Unless the NY Times has changed its policy everybody has 20 free articles a month before they must subscribe. With luck this excellent essay should come up on your screen. "Blind photographer" turns out to be not as wild a joke as I originally thought. But that problem seems to have stabilize so it is unlikely you will ever see an image of me sprawled on the the sidewalk next to a stack of blurry prints, an old can and a sign saying 'please support this near blind photographer.' And partly because of a real medical condition effecting my eyesight brought on by, among other things, being too friendly with a high powered UV laser during my misspent youth. It's partly because of the press of other commitments, also known as procrastination.
