Convert DNG to PPM

The Digital Negative (DNG) file extension, developed by Adobe Systems and introduced in 2004, is an open, lossless raw image format designed for digital photography. DNG aims to provide a standardized format for raw files, ensuring compatibility across various software and hardware platforms. It is based on the TIFF/EP standard and incorporates extensive metadata, making it suitable for long-term archival purposes. DNG files are widely supported by numerous camera manufacturers and software applications, facilitating efficient storage, sharing, and editing of high-quality images.

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.
