DNG

The DNG (Digital Negative) format is a royalty-free file format for raw images developed by Adobe. It serves as a universal standard that preserves the integrity of original raw images while allowing for easy editing and archiving. By supporting DNG, photographers ensure compatibility with a wide range of software and equipment, enhancing workflow efficiency and image preservation.

PPM

The Portable Pixmap Format (PPM) is a simple and widely-used image file format that stores pixel data in a human-readable format. Ideal for basic graphics applications, PPM files support RGB color encoding and are versatile for both software developers and graphic designers. Despite larger file sizes compared to compressed formats, PPM's simplicity makes it a preferred choice for image manipulation and teaching digital imaging concepts.
