This approach is used extensively in cinematography and is known to be much more robust than the traditional display-referred approach. If you have used other Raw software in the past (or darktable prior to version 3.0) you may notice some significant differences from what you are used to – darktable now uses a scene-referred approach for most of its processing modules. 🔗scene-referred workflow: a new approach As a general rule of thumb, it is safe to under-expose all images by 0.5 to 1 EV (by reducing the ISO sensitivity if possible) even if the in-camera preview looks darker than expected (the preview is not the raw data). Where possible, you are advised to use exposure to-the-right (ETTR) techniques to maximize the amount of data available for processing. Under- or over-exposure can be “fixed” by darktable to some extent but no software can recover information that is not present in the Raw image. Good image processing techniques start in the camera – a well-exposed image (without blown highlights or heavily crushed blacks) will always make post-processing much more straightforward. 🔗getting started 🔗take a well-exposed photograph You are advised to follow the guidelines provided below, up to the end of the image processing in 3 modules section and then choose other areas to learn as-and-when you need to use those techniques in your images. This section is intended to get you comfortable processing images in the darkroom view using a scene-referred workflow.
