Convert PPM to FL32

The Portable Pixmap (PPM) file extension, an image format within the Netpbm family, stores simple, uncompressed images. Introduced in the late 1980s, PPM supports RGB color and grayscale images, making it suitable for basic image processing and conversion tasks. Its plain text encoding simplifies debugging and data manipulation, although its lack of compression results in larger file sizes compared to modern formats. As such, PPM finds limited use in contemporary applications, mainly in educational and experimental settings where ease of implementation and readability are prioritized.

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.
