Convert NEF to PHM

The NEF file extension stands for Nikon Electronic Format, a proprietary RAW image file format used by Nikon digital cameras. These files capture all image data as seen by the camera sensor, providing greater flexibility for post-processing and higher image quality compared to compressed formats. NEF files are essential for professional photographers and IT specialists in photo editing due to their uncompressed nature, allowing precise adjustments in color, exposure, and detail retention. Nikon introduced this format to enhance image fidelity and editing capabilities, maintaining a pivotal role in digital photography since its inception.

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.
