Convert NRW to PBM

The NRW file extension stands for Nikon Raw Image, a proprietary raw image format used by Nikon digital cameras, particularly the high-end COOLPIX models. NRW files store uncompressed, unprocessed image data, allowing for greater post-processing flexibility and higher image quality compared to compressed formats like JPEG. Introduced to support Windows Imaging Component (WIC) functions, NRW files enable photographers to adjust color, brightness, and other image attributes with precision. Compatible with various image editing software, including Nikon ViewNX2 and Adobe Photoshop, NRW files are essential for professional photography.

The PBM (Portable Bitmap) file extension, part of the Netpbm project, originated in the late 1980s to facilitate efficient and portable graphics file interchange. Primarily, PBM files are used to store monochrome bitmaps in a simple ASCII text format, ensuring easy compatibility across different systems and platforms. This format supports only black-and-white imagery, making it particularly useful in scenarios where simplicity and minimalism are prioritized, such as in Unix environments for bitmap manipulation and transfer. Its historical significance lies in promoting a standardized approach to bitmap graphics in early computer technology.
