Convert X3F to HDR

The X3F file extension, associated with Sigma Digital Camera Raw Image File, is a proprietary format created by Sigma Corporation for cameras with Foveon X3 sensors. X3F files store raw image data, capturing full-color information at each pixel for enhanced color accuracy and detailed post-processing. This format includes metadata, thumbnails, and preview images, offering photographers comprehensive control over their images. While primarily processed with Sigma Photo Pro software, X3F files are also supported by plugins for popular photo editing software like Adobe Photoshop.

HDR stands for High Dynamic Range, and in the context of Radiance, it refers to a file format used for storing high-quality images. The Radiance HDR format was developed as part of the Radiance rendering system, which originated in the late 1980s at the Lawrence Berkeley National Laboratory. Its primary use is in the field of computer graphics, where it captures a wider range of luminance levels compared to standard formats, enabling more realistic lighting effects. This format is particularly beneficial for tasks requiring precise light measurements and accurate visualizations, making it indispensable for professionals in fields such as architectural visualization and visual effects.
