Convert PEF to HDR

The PEF (Pentax Electronic File) is a raw image file format used by Pentax digital cameras. It contains unprocessed data directly from the camera's image sensor, allowing for greater post-processing flexibility and higher-quality images. Introduced by Pentax, this format retains more image information compared to compressed formats like JPEG, making it popular among professional photographers. PEF files can be opened and edited with various software, including Adobe Photoshop and Pentax's own Digital Camera Utility.

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.
