Convert PBM to FL32

The PBM (Portable Bitmap) file extension, part of the Netpbm project, originated in the late 1980s to facilitate efficient and portable graphics file interchange. Primarily, PBM files are used to store monochrome bitmaps in a simple ASCII text format, ensuring easy compatibility across different systems and platforms. This format supports only black-and-white imagery, making it particularly useful in scenarios where simplicity and minimalism are prioritized, such as in Unix environments for bitmap manipulation and transfer. Its historical significance lies in promoting a standardized approach to bitmap graphics in early computer technology.

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.
