Convert K25 to PHM

The K25 file extension stands for Kodak DC25 Digital Camera Raw Image. It is a proprietary format used by the Kodak DC25 digital camera, introduced in the mid-1990s. K25 files store unprocessed image data directly from the camera's sensor, preserving high image quality and allowing extensive post-processing. This format was pivotal in early digital photography, enabling users to manipulate images without significant quality loss.

The PHM file extension stands for Portable Float-map Image (16-bit half), a format used for storing High Dynamic Range (HDR) images with 16-bit half-precision floating-point values. This format is particularly useful in applications requiring precise color representation and extensive dynamic range, such as computer graphics, image processing, and scientific visualization. Originating from the Portable FloatMap (PFM) format, PHM was developed to provide a more efficient storage solution by utilizing half-precision floats, thereby reducing file size while maintaining significant detail and accuracy.
