Convert OTB to FL32

The OTB (Over The Air Bitmap) file extension, developed by Nokia, is used for transmitting black and white bitmap images between mobile phones, particularly Nokia and Siemens models. These images, with a maximum resolution of 255x255 pixels, are often sent via SMS in either hexadecimal text or binary format. Historically, OTB files were popular in the early days of mobile communication for sending simple graphics, icons, and wallpapers when data transmission speeds were limited.

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.
