NEF
NEF, or Nikon Electronic Format, is a proprietary RAW image file format used by Nikon digital cameras. It captures unprocessed image data directly from the camera's sensor, allowing for extensive post-processing flexibility. NEF files maintain high image quality, retaining details and colors. Ideal for professional photographers and enthusiasts, NEF supports advanced editing workflows while providing superior image fidelity.
PNM
PNM (Portable Any Map) is a versatile file format for storing and manipulating images. It supports grayscale, black and white, and color images, making it ideal for various applications in graphics processing. PNM files are easily readable and widely supported by image editing software, offering a simple yet effective way to handle image data without loss of quality.
