Convert PFM to FL32

The Portable Floatmap (PFM) file format, also known as Portable FloatMap, is an image file format designed to store High Dynamic Range (HDR) images using floating-point values. Developed in the spirit of the Portable Pixmap format, PFM files contain image data with resolutions and byte order specified in the header. This format is particularly useful for applications requiring precise image data, such as computer graphics and image processing. PFM has been widely adopted in the IT industry for its ability to handle a wide range of pixel values beyond the standard 0-255 range, making it ideal for HDR imaging and other advanced visualizations.

The FL32 file extension stands for FilmLight Floating-point Image, used primarily within the Baselight color grading and finishing platform developed by FilmLight. This format supports high dynamic range imaging by utilizing 32-bit floating-point precision, ensuring accurate color representation and extensive post-production flexibility. Introduced to meet the demanding requirements of professional film and video production, FL32 files facilitate advanced color correction and visual effects workflows, maintaining high fidelity throughout the editing process.
