浏览Darktable 是一个非常全面的照片处理程序,可让您在数字暗房中编辑 RAW 图像文件。我们的想法是能够处理您的底片,并以非破坏性的方式轻松返回原始方式。该程序与 400 多种不同的相机型号兼容,让您可以通过无穷无尽的功能完整、专业地编辑您的照片。
在处理照片时,您可以从台式计算机或直接从您使用的相机导入它们。 Darktable 的伟大之处在于它提供了一个完整且可定制的导入系统。例如,它甚至可以让您将一系列照片变成延时摄影,以及其他选项。
darktable 是由摄影师为摄影师创建的。
将同时也是狂热摄影师的开发人员作为目标受众的一部分,有助于了解现实世界的问题、挑战和工作流程。
darktable 是一个摄影工作流程应用程序和原始开发人员。供摄影师使用的虚拟灯台和暗室。它在数据库中管理您的数字底片,让您通过可缩放的灯台查看它们,并使您能够开发原始图像并增强它们。
darktable 在整个流程中以非破坏性方式编辑您的图像。您的原始图像永远不会被修改。专业的色彩管理功能可确保打印过程的保真度,GPU 加速处理意味着您可以使用显卡加快工作流程。
目前darktable包含61个图像操作模块。许多模块支持强大的混合运算符,提供混合功能,适用于输入图像信息和当前模块的输出,或与绘制的蒙版一起使用。
darktable 4.6.0
December 21, 2023
Editing history is now periodically auto-saved (every 10 seconds) while editing images in the darkroom view. The auto-save interval can be changed (via a preference) or auto-save can be disabled entirely (by setting the interval to 0).
A new processing module rgb primaries has been added. This module can be used for delicate color corrections as well as creative color grading. It allows the red, green and blue primary colors to be moved around using “hue” and “purity” controls.
The underlying pixel operation is essentially the same as channel mixing.
In addition, the sigmoid module now includes a new primaries section, which can be used to gracefully handle difficult lighting situations (e.g. LEDs) and tune the overall look of the image. Modifying these parameters can provide pleasing sunsets, improved skin tones etc. This feature can only be used with sigmoid’s per-channel mode and is loosely based on ideas from Troy Sobotka’s AgX and related work in the Blender community. The included “smooth” preset should provide a good starting point for further corrections using this feature.
When working with the liquify and retouch modules, the full uncropped image is now always shown, with any crop indicated by displaying an overlaid rectangle. This allows for cropped-out parts of the image to be used without having to first disable the crop module and re-enable it when finished.
When panning or zooming in the darkroom view, a low resolution placeholder used to be shown until the image was fully recalculated for the newly-visible region. Now, if any part of the previous view is still visible, that part will be immediately shown in high quality, with only the remainder of the image being temporarily shown in low quality until the pipe has finished.
This has been achieved as part of a complete reworking of the darkroom image display, which has also removed some annoying jumps when replacing the low resolution placeholder with recalculated image data, or when switching between full and cropped view (when the crop, retouch or liquify modules are (un)focused).
Performance Improvements:
OpenCL is now initialized in the background immediately after launching the darktable UI, with progress indicated by a series of toast messages. Previously, this was done before the main UI was launched, which could lead to significant delays (sometimes more than a minute) between the user opening darktable and anything appearing on-screen, making it appear as though darktable had failed to start. Note that processing will be slower (since darktable will only use the CPU) until OpenCL is fully initialized.
An OpenCL code path has been implemented for lens correction using embedded correction metadata.
Image display speed in the map view has been increased by 25%.
Export speed has been improved for JPEG 2000 and B&W TIFF images.
The chromatic aberrations module is now approximagely 10% faster when run on the CPU.
