#Darktable editing series#
When this is done, you can measure the brightness and chromaticity of a control sample, preferably located on a non-moving surface that is consistently lit across your series (and appearing in all the frames). Next, proceed with the filmic rgb white and black relative exposures, as well as the contrast setting. What remains to complete this stage is to adjust the exposure setting to match the overall brightness that you expect. Your primary color-grading should already be handled by the profile used in the color calibration module (in conjuction with the input color profile module). See the documentation in the color calibration module for more information.Ĭhoose a reference image that was taken in the lighting conditions closest to those of the color checker image that served as your profiling reference. Note: this process only works with the modern chromatic adaptation workflow, which assumes hard-setting the white balance to a D65 ( camera reference) illuminant. This step needs to be repeated for each camera and lighting setup. This profile can then be applied to all images shot under the same lighting conditions with the same camera by copying and pasting the development history stack in the lighttable view. You will first need to extract a color calibration profile from the image(s) of your color checker. For example, if a non-neutral white balance is expected in the series, it is much easier to re-introduce non-neutrality in color balance rgb (using the same color shift) on fully-neutralized images, than to fine-tune the primary color-grading individually on each image, especially if several different cameras were used. In a nutshell, the whole purpose of the primary color-grading is to ensure the repeatability of the secondary color-grading between images. If and only if the primary color-grading was successful at perfectly neutralizing all images to the same ground-truth, copying and pasting the secondary color-grading steps between images should have exactly the same visual effect on each image, no matter if the images were shot with a different camera or under slightly different lighting conditions. This is where all the artistic expression happens, with modules such as color balance rgb. Secondary color-grading happens next in the pixel pipeline and in the editing workflow. Primary color-grading is not about artistic intent or expression, but simply about preparing a sane and consistent basis for the next stage. This stage aims at making all images look similarly boring by removing any color cast and ensuring a perfectly neutral white, and is particularly important if your series uses different cameras. Its purpose is to normalize each image to the same neutral ground-truth, in terms of overall brightness, color accuracy and white balance. Primary color-grading is performed first in the pixel pipeline and in the editing workflow, with modules such as exposure, input color profile and color calibration. The post-processing needs to be split in 2 fully separated parts: In terms of post-processing, any variation means that individual adjustments will be needed on each image, which will hinder your productivity.
#Darktable editing manual#
If possible, shooting in manual mode with constant exposure settings will help to remove some variability in the series. Shoot a new image of the same color checker every time your lighting conditions change. This means that you won’t have to worry about light color temperature and intensity changes between images. If possible, use controlled artifical lighting to maintain consistent lighting over the series of images. The image of the color checker can be quickly used as a color reference in the post-processing workflow to neutralize any color cast – Datacolor and X-Rite color checkers (24 and 48) are natively supported. Shooting a color checker on-location can save a tremendous amount of time during batch post-processing of a series of images. It can be a tedious, frustrating and unexciting task, so darktable includes functionality to help make it faster and more reliable.
It features live preview of the styles with four different sample images.Batch-editing is the process of developing images in a semantically-related series that are expected to have a consistent final look, often with the intent of publishing the images in catalogues, magazines or books.
