darktable 0.8 released with many major new features
At last darktable 0.8 is out with major new changes. For those who isn't familiar with dt, it's very much like Adobe Lightroom, but is free and runs on Linux.
For those who isn't familiar with dt, it's very much like Adobe Lightroom and Aperture, but is free, plugin-based and runs on Linux. This is not to say that those apps don't have plugins, on the contrary: there's quite a lot of plugins for Adobe Lightroom and some other commercial digital photography workflow apps. But darktable's architecture is based entirely on plugins.
One of the most exciting new features in this version is much faster loading and processing which is possible thanks to Rawspeed library (by Rawstudio project) and OpenCL (you need binary Nvidia/ATI drivers or Gallium 3D).
Light table mode has been improved: you can now use simple boolean (AND, OR, NO) operations to construct dynamic collections from filmrolls, tags, color labels and XMP metadata.
Another new feature is a basic metadata editor that simplifies work of a photographer who works for an agency or uploads his work to microstocks. You can easily create presets and apply them to selection of images. The editor is also available in the tethering mode.
Speaking of tethering mode, you can now shoot bracketed pictures there. Then, in light table mode, you only need to select them and click "Combine to HDR" button to get and HDR file that will automatically be non-destructively tonemapped with a modification of Durand's tonemapping operator.
Finally, some new filters were written instead of older, not so good ones, and some of them are also disabled by default, because they are unfinished.
A special note should be said about demosaic: this part was rewritten very nearly from scratch. No longer you have to reimport an image after you enabled green channel equilibration or automatic correction of chromatic aberrations. Now demosaic is a regular plug-in whose changes show up in the history panel. And CA corrections are a standalone plug-in as well. So handy!
