- Description
- The PNM (Portable Any Map Image) file format is a subset of the broader Netpbm format, designed for storing various types of digital images. It acts as an umbrella term for three specific types of grayscale, color, and black-and-white images, represented by PBM (Portable Bitmap), PGM (Portable Graymap), and PPM (Portable Pixmap) formats respectively. PNM files are known for their simplicity and ease of conversion to other image formats.
- Raster image or digital photo saved in HDRsoft's High Dynamic Range (HDR) image format; used for enhancing the color and brightness range of a digital image; can be processed to fix dark shadows or washed out areas of a picture.
