Description
The CRW file format is a type of raw image file created by Canon digital cameras. It stands for Canon Raw CIFF (Camera Image File Format), which is a proprietary file format developed by Canon for capturing all the image data recorded by the camera's sensor when a photo is taken. Unlike JPEG or other compressed image formats, CRW files contain uncompressed and unprocessed data, offering photographers a higher degree of control over image adjustments such as exposure, white balance, and color corrections during the post-processing.
The Flexible Image Transport System (FITS) file format is a digital file format used primarily in astronomy for storing, transmitting, and analyzing scientific images and data. Developed in the late 1970s, FITS was designed to provide a standard for the interchange of astronomical data, facilitating the sharing and analysis of data among astronomers and researchers worldwide.
