Having got some of that architecture out of the way, darktable is easy to use, as long as one realizes that there is usually more that one way to do something, but one way is easier and better than the others! It’s also heavily customizable. Sigmoid is a newer addition, easier to use (arguably) and I often prefer it, so I stick to that usually, although filmic rgb is considerably more flexible in some situations. They both do the same job, and can give very similar results. The current release of darktable, version 4.2, has two very good tone mappers – filmic rgb and sigmoid. In scene-referred, the last module in the pipe is the tonemapper (not to be confused with the nasty “HDR” style of tonemapping), which compresses the wide dynamic range into the output, in the way you want. Modern cinema editing is done this way, apparently. In effect, it’s the ultimate in non-destructive editing, because you have access to all the data you captured while you work on the image. That doesn’t affect the order in which you apply adjustments, but it does have an effect how adjustments respond. This just means that all (or most) of the adjustments on your image are done before the tone curve (or “tone mapper”) that translates the wide dynamic range captured by your camera into the the range that can be fitted into a jpg, or displayed on a screen. Going back to the pixelpipe, darktable, by default, works in a scene-referred workflow. I have a low-mid range Nvidia GPU which makes all the difference to speed and responsiveness with modules like diffuse and sharpen. It’s beneficial to have a GPU (graphics card) in your machine – some modules are quite computationally intensive, and darktable can use OpenCL acceleration. Of course, once you’re done editing, it will export to JPG, TIFF or whatever. a LUT, that would need to be present too. The only exception is if you used an external file, i.e. xmp sidecar file with the raw, and in almost all cases you have your complete edit. If you wanted to transfer to a different computer, also running darktable, you only need to ensure that you copy the. It is totally non-destructive, like all decent RAW processors, and the adjustments you make are saved in its database (like Lr) and if you want, also in a sidecar file, which means you don’t need to have access to the database to retrieve your edits. These are both a little more traditional in approach, and very good as well.ĭarktable is different in how it works: you have a concept called the pixelpipe, which consists of modules each of which have an effect on the image. For anyone who doesn’t like the way darktable does things, but does like the open source nature of it, I would suggest trying RawTherapee or ART (A Fork of Rawtherapee), a variant of it. It can be a bit divisive at times – many people love it, but there are also those who don’t like it. I used a Pentax 50mm f1.7 K-mount that I stripped and cleaned for this image. It’s available for Linux, Windows and Mac. However, and I must stress this, it is not a copy of, nor a direct replacement for Lightroom! Some would argue I shouldn’t even have made the comparison, but I thought it was the simplest way to describe what it does. Like Lr, its primary purpose is developing RAW images, as well as organizing them and so on. If you’re familiar with the ubiquitous Adobe products, darktable (often known as dt) is closest to Lightroom. It’s developed by a hard working team of volunteers, who I have enormous respect for. You can take the code to pieces if you want (and are able to…) and make your own version. Open source means it’s free, both in terms of cost (in this case and many others, but not all), and in terms of what you do with it. Darktable is open source image workflow software.
