![]() So you will probably think, how can every pixel on a sensor capture all the colors if each pixel is assigned a specific color filter and can only register the intensity of one of these three basic colors? So how is it handling the two missing colors? So per pixel the RAW file contains the intensity of the light that was registered and because of the individual color filters on each pixel it contains the light intensity of a specific color per pixel. This is the information that is actually the foundation for the RAW file. The Bayer pattern is based on a distribution of 50% green, 25% red and 25% blue filters over the surface of a camera sensor.įor example, if a specific pixel has been assigned a red filter, this filter blocks the colors green and blue. For example Fujifilm uses, for specific reasons which I won’t discuss here, its own pattern called X-Trans. One of the most commonly used patterns is called the Bayer pattern, but there are other patterns as well. These miniscule color filters, being a red, green or blue filter, are placed in a specific pattern. To solve this problem, a method has been devised to place individual color filters over every single pixel on the sensor. So it is basically a black and white sensor and without additional technologies we would get a grayscale picture. It only can see differences in light intensity. ![]() The core problem is that a camera sensor actually can’t see color. RAW is a file format in which all image data that a camera sensor registers is actually stored in a … well … raw format. Technically, every digital camera always first captures a picture in RAW format. About RAWīefore we go deeper into darktable itself, it is good to first understand what the RAW file format means and what the advantages are compared to shooting in JPEG format. I don’t know yet how many articles I will be devoting to this series, but I expect that I will focus on many editing modules, and in addition, new functionalities will be added regularly by the developers, so this will hopefully be a continuously growing series. Hence the start of this new tutorial series. More and more I get questions or comments from readers about darktable for Linux and that is why I believe that many users who want to use their Linux system productively, would like to read about the possibilities of darktable on this website. ![]() It offers a great photo platform for both serious enthusiasts and professionals. For me personally, darktable surpasses the other software solutions because of the flexibility, adjustability, customizability, the enormous amount of selectable but also concealable high-quality editing modules and the many precision options for editing locally. I have tried all these applications to determine which software best fits my way of working and my specific requirements. A surprisingly large number of high-quality RAW editors are available for Linux, such as RawTherapee, GTKRawgallery, Lightzone and of course also darktable. However, when my interest in Linux was sparked, I started to look for usable open source alternatives to process my RAW photo files. My plan for this website is to get more and more focussed on timeless, in-depth Linux related articles and series of articles that can help people to use their Linux system more productively.īefore I made a full switch to Linux a few years ago, I used Adobe Lightroom on the macOS operating system to process my RAW files for both my personal photography and my professional photo work. My goal is to regularly come up with new in depth darktable tutorials on specific concepts and functionalities and slowly work towards an accessible, but quality reference on darktable. This article is the start of my new tutorial series on darktable. Why this new tutorial series on darktable ![]() Why this new tutorial series on darktable.In this first article in hopefully an extensive series, I will give a first introduction into darktable, as a general background and guidance for all upcoming more in-depth articles about specific darktable functionalities. And in my opinion the fulfillment of those needs is offered to us in the form of the powerful open source solution darktable. ![]() But we do have similar needs when it comes to serious editing of RAW photo files and associated workflow support. But as lovers of Linux and open source software, we do not have Lightroom. And I still think that Lightroom is a great and robust software solution to organize and edit RAW photo files on your macOS or Windows system, next to products like Capture One Pro or ON1 Photo RAW. Adobe’s Lightroom has been the de facto standard for professional and serious RAW processing for Windows and macOS for years. Before I came into contact with Linux, as a lifelong passionate landscape, and later portrait and wedding photographer, I had been using Adobe Lightroom on an Apple based system already for a long time. ![]()
