Convert NRW to CALS

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 CALS (Continuous Acquisition and Life-cycle Support) Type 1 Image file format, developed by the United States Department of Defense in the mid-1980s, is a standard for storing raster (bit-mapped) image data, typically black-and-white. It ensures efficient data interchange and retention of orientation metadata. The format supports both uncompressed and compressed (using CCITT Group 4 compression) images. This standard was part of the broader CALS initiative aimed at improving electronic publishing and data management within the federal government.
