Convert DCR to PHM

The DCR (Digital Camera Raw) file extension is used by Kodak digital cameras to store uncompressed, lossless image data exactly as captured by the camera's sensor. This format retains more detail and allows for greater post-processing flexibility compared to compressed formats like JPEG. DCR files contain metadata such as camera settings and image dimensions. Historically, Kodak introduced this format to provide photographers with high-quality images for editing and archival purposes.

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.
