Convert NEF to CAL

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 CAL file extension, known as CALS (Continuous Acquisition and Life-cycle Support) Type 1 Image, is a 1-bit black-and-white raster image format developed by the U.S. Department of Defense in the mid-1980s to standardize graphics data interchange for military documentation. It is primarily used for storing and sharing monochrome images while retaining orientation metadata. The format supports both uncompressed and compressed (using CCITT Group 4 compression) images.
