In the realm of digital art and graphic design, understanding how to properly save HDR (High Dynamic Range) images in Blender is crucial to preserve the intricate details and wide dynamic range that distinguish HDR images from their standard counterparts. Saving HDR images allows artists to retain the full spectrum of colors and lighting, resulting in a more realistic and visually captivating final product. This comprehensive guide will provide a step-by-step walkthrough of the essential techniques for saving HDR images in Blender, ensuring that your creations are showcased at their optimal quality.

Before delving into the specifics of saving HDR images, it’s essential to understand their unique characteristics and advantages over standard images. HDR images capture a broader range of colors and luminance levels compared to traditional 8-bit per channel (8-bit/ch) images. This expanded range allows artists to depict scenes with extreme contrasts, such as a cityscape at dusk where both the bright city lights and the dark night sky are simultaneously visible with remarkable clarity. Additionally, HDR images support a higher bit depth, typically 16-bit/ch or 32-bit/ch, which enables even more precise and nuanced color transitions within the image.

To successfully save HDR images in Blender, several key settings must be configured within the software. First, ensure that the “Scene Linear” option is enabled in the “Color Management” panel under the “Scene” settings tab. This setting ensures that Blender uses a linear color space, which is necessary for accurately representing and preserving the wide dynamic range of HDR images. Next, select the desired file format for saving the HDR image. Blender supports various HDR formats, including OpenEXR (.exr), Radiance (.hdr), and LogLuv (.lwl). Each format has its strengths and limitations, so choose the one that best suits your specific requirements. Finally, adjust the “Output > File Format” settings to match the selected HDR file format and set the bit depth to 16-bit/ch or 32-bit/ch depending on the desired image quality.

How to Save HDR in Blender

Saving HDR images in Blender is a straightforward process that can be completed in just a few steps:

  1. Render your image as usual.
  2. In the Render Properties panel, find the “Output” section and change the “File Format” to “OpenEXR (.exr)”.
  3. In the “Color Depth” field, select “16-bit Half”.
  4. Click the “Render” button to save your image.
