Under the Post Processing tab, you can adjust several exposure settings (e.g., brightness, contrast, gamma, and exposure) as well as adjust the luminosity curve. And in the Color Management section, you can specify a color profile and a color space (refer to Color Management in digiKam for more info on color management). Using the options in the Corrections section, you can choose to apply one of the supported noise reduction algorithms to the image as well as enable the chromatic aberration correction option and adjust its settings. The under- and overexposure buttons at the bottom can identify under- and overexposed areas of the photo in the preview pane, which can help you to adjust exposure settings. Besides white balance, you can also enable and adjust the Exposure Correction option and manually tweak exposure compensation settings. And if you want LibRaw to automatically adjust brightness, tick the Auto Brightness check box. To process highlights more accurately, enable the Correct false colors in highlights option. LibRaw offers several algorithms for restoring highlight clippings - Solid White, Unclip, Blend, and Rebuild - and you can view their brief description by using the Shift + F1 keyboard shortcut. In the White Balance section, you can adjust white balance settings and specify how the system should handle highlight clippings (overexposed areas in the photo). This option also prevents the image from stretching to its correct aspect ratio. When this option is enabled, the image is titled 45 degrees, so that each output pixel corresponds to one RAW pixel. The Do not stretch or rotate pixels option is there specifically for Fujifilm’s cameras with the Super CCD sensors and cameras using sensors with non-square pixels. Enabling the Interpolate RGB as four colors option can fix that. Due to the way certain algorithms process green pixels, the resulting image can contain undesirable patterns and artifacts. If you choose to work in the 16-bit mode, it’s recommended that you enable and configure color management options in the Color Management section to prevent dark rendering of the image in the editor. The 8-bit mode is faster, but the 16-bit conversion is by far the best way to go, as it provides better tonal range. The preview pane displays an image that will be imported in the editor, and you can use the zoom slider at the bottom of the window to zoom in on the image for closer examination.īy default, digiKam converts RAW files into 8-bit color images, but you can choose the 16-bit mode instead by enabling the 16 bits color depth option.

Select the algorithm you want, and press the Update button to preview the result. But the best way to see the differences between different algorithms is to try to apply them to the currently opened RAW file. You can use the Shift + F1 keyboard shortcut to view a brief, and rather technical, description of each algorithm. digiKam (or rather the LibRaw library) supports several demosaicing algorithms, including Bilinear, VNG, AHD, LMMSE, and others. To better understand what demosaicing is and how it works, you might want to check the Understanding Digital Camera Sensors article.

The RAW Decoding section gives you access to settings that let you tweak demosaicing, white balance, noise reduction and chromatic aberration correction, and color management settings.ĭemosaicing is a process of reconstructing a full color image from the raw output of an image sensor.

The RAW Import sidebar contains three tabs: RAW Decoding, Post Processing, and Info.
