Convert RAW to PHM

The RAW file extension, standing for "Raw Image Data File", is used to store unprocessed image data captured by digital cameras or scanners. This format preserves the highest level of detail and dynamic range, allowing for extensive post-processing without quality loss. Originating in the early days of digital photography, RAW files have become essential for professional photographers and graphic designers who require maximum control over image adjustments such as exposure, white balance, and color correction. The format's ability to retain all sensor data makes it invaluable for producing high-quality, editable images.

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.
