Calibrating Your Monitor for Accurate Colors

Calibrating your monitor is crucial for ensuring accurate color representation in your images. Without a calibrated monitor, the colors you see on your screen may not be accurate, leading to incorrect adjustments and unsatisfactory results. For a more in-depth explanation, see our article on Monitor Calibration for Photographers. Relying on generic ICC profiles is not recommended, as they may not be suitable for your specific monitor. Instead, it is recommended to prioritize calibrating your own monitor.

To calibrate your monitor, you’ll need a calibration device, such as a colorimeter or spectrophotometer. These devices measure the colors displayed on your screen and create a custom ICC profile that corrects any inaccuracies. Once you’ve created a profile, load it into your operating system and Darktable for accurate color representation. If you have outdated ICC Profile Recommendations, create your own profiles. You may also want to check the monitor manufacturer’s website.

Configuring Hardware Acceleration (GPU)

Hardware acceleration utilizes your computer’s graphics card (GPU) to speed up image processing tasks in Darktable. This can significantly improve performance, especially when working with large RAW files.

To enable hardware acceleration in Darktable, go to Settings > Processing and enable the “opencl” option. Darktable will automatically detect your GPU and use it for processing. If you experience any issues, make sure your GPU drivers are up to date. For optimal performance, look for GPUs with good OpenCL support and sufficient VRAM (4GB+ for large RAW files). NVidia, AMD and Intel ARC integrated graphics cards will generally work.

Integrated GPUs can work well, but may be limited by shared system RAM. Reference benchmarks for hardware on sites like Phoronix. It is important to avoid relying on Outdated Hardware Acceleration Advice and instead focus on the latest trends.

Importing and Organizing Your RAW Photos

Importing your RAW photos into Darktable is the first step in your RAW processing workflow. To import photos, simply drag and drop them into the Darktable window or use the “Import” button.

A well-organized file structure is essential for managing your photo library. Create a system of folders and subfolders to categorize your photos by date, event, or project. Use descriptive filenames to make it easier to find specific images. Darktable Catalogs can help you to manage files, ratings, and metadata effectively.

Step 1: Basic Corrections (Exposure, White Balance)

The first step in your workflow should be to make basic corrections to the exposure and white balance of your image. Use the Exposure module to adjust the overall brightness of the image. Increase the exposure to brighten the image or decrease it to darken it. Use the Contrast slider to increase or decrease the contrast between the highlights and shadows. Adjust the Highlights and Shadows sliders to recover details in overexposed or underexposed areas.

Use the White Balance module to correct any color casts in your image. You can use the presets (e.g., Daylight, Cloudy, Tungsten) or make custom adjustments using the Color Temperature and Tint sliders.

Step 2: Tone Mapping with Filmic RGB (The Modern Approach)

Tone mapping is the process of adjusting the dynamic range of an image to fit the capabilities of a display device. In Darktable, the primary tool for tone mapping is Filmic RGB. As Outdated Tutorials (Darktable Version) will show, there was once Base Curve, but now there is Filmic RGB.

Filmic RGB offers several advantages over the older Base Curve module. It provides more natural-looking results, better highlight and shadow recovery, and greater control over contrast and dynamic range. Use the Filmic RGB module to control the overall look and feel of your image.

Step 3: Color Grading and Enhancement

Color grading is the process of adjusting the colors in your image to create a desired look and feel. Use the Color Balance RGB module to make precise adjustments to individual color channels. Adjust the Saturation slider to increase or decrease the intensity of the colors. Use the Vibrance slider to boost the saturation of muted colors without affecting already saturated colors.

Step 4: Detail Enhancement (Sharpening, Local Contrast)

Detail enhancement is the process of enhancing the sharpness and clarity of your image. Use the Sharpen module to sharpen the details in your image. Be careful not to over-sharpen, as this can create unwanted artifacts. Use the Local Contrast module to add depth and dimension to your image.

Step 5: Noise Reduction (Including AI-Powered Options)

Noise reduction is the process of removing unwanted noise from your image. Noise can be especially problematic in low-light situations or when shooting at high ISO settings.

Use the Denoise (profiled) module to remove noise without sacrificing detail. This module uses advanced algorithms to identify and remove noise while preserving the sharpness and clarity of your image. Noiseflow is an AI-powered noise reduction plugin for Darktable. AI-Powered Noise Reduction is rapidly improving, but it’s still in early stages.

Step 6: Exporting Your Final Image

Exporting your final image is the last step in your RAW processing workflow. Darktable offers a variety of export options, allowing you to choose the right settings for different output formats and purposes.

Use the Export module to export your image. Choose the desired file format (JPEG, TIFF, etc.), quality settings, and output size. You can also add metadata and watermarks to your exported image. Export files for printing, web or other purposes.

Filmic RGB: The Key to Modern Tone Mapping
