Convert ARW to PHM

The ARW file extension stands for Sony Alpha Raw, a raw image file format used by Sony's Alpha series digital cameras. ARW files contain uncompressed, minimally processed data directly from the camera's sensor, allowing photographers to achieve higher-quality images and more precise edits. Introduced with Sony's Alpha DSLR series, this format is based on the TIFF specification and requires specialized software, such as Adobe Photoshop or Sony's Imaging Edge, for viewing and editing.

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.
