Convert NEF to PPM

The NEF file extension stands for Nikon Electronic Format, a proprietary RAW image file format used by Nikon digital cameras. These files capture all image data as seen by the camera sensor, providing greater flexibility for post-processing and higher image quality compared to compressed formats. NEF files are essential for professional photographers and IT specialists in photo editing due to their uncompressed nature, allowing precise adjustments in color, exposure, and detail retention. Nikon introduced this format to enhance image fidelity and editing capabilities, maintaining a pivotal role in digital photography since its inception.

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.
