HDRIs capture real-world lighting conditions, including bright light sources such as the sun, artificial lights, or reflections. Bloom light extraction from an HDRI highlights natural light behavior, such as the softening and spilling of light around bright areas, creating a more realistic effect. Often, HDRIs are cleaned up by removing the sun and surrounding areas to use them as diffuse maps in 3D software. However, this approach is not ideal. Why Extract the Sun and Bloom? The sun in an HDRI has specific values, including its proper range and temperature, which correspond to the exact time and place of capture. These values are crucial for accurate rendering of reflections and refractions in a 3D scene. Similarly, the areas surrounding the sun also have distinct ranges that are just as important as the sun itself. By carefully extracting bloom, you can preserve these critical details and achieve more precise and realistic results in your renders. Here is another tool you can use for sun extraction: HDRI Sun Extract This tool is specifically designed to help extract the sun from HDRIs effectively. You can download it from Nukepedia. By using this tool, you can simplify the process of isolating and managing the sun in your HDRI workflows, ensuring better control over your lighting and rendering results.

If you truly want to achieve a realistic match with onset lighting in a 3D environment, it is crucial to extract the key light sources, such as the sun or other significant light emitters, from the HDRI and accurately position them within the 3D space using lights. The importance of extracting sunlight:- In particular, cannot be overstated. While it is common practice to paint out the sun and bloom areas from the HDRI and export the image for use as a diffuse and reflection map—which is indeed beneficial—this approach alone may not suffice for photorealistic rendering. The sunlight and other key light sources in an HDRI typically possess a wide dynamic range in terms of exposure and color information. By extracting and replicating these lights separately within the 3D scene, you can effectively recreate their intensity, direction, and color attributes, resulting in a far more realistic and accurate representation of the original lighting conditions. This process ensures that the lighting in your render has the depth, variation, and accuracy needed to achieve a truly photorealistic output.
