What is a RAW file format?

A RAW file format is an unprocessed image file that captures all the data from a camera’s sensor without applying any compression or processing. This means that when you take a photo in RAW format, the image retains the maximum amount of detail and dynamic range, providing photographers with greater flexibility during post-processing. RAW files allow for significant adjustments in exposure, color correction, and white balance without sacrificing image quality, making it the preferred format for professional and serious photographers.

In contrast, high-compression image files often lose some data quality in order to reduce file size, which can limit editing capabilities. Automatic image formats typically refer to formats that are processed or saved with pre-set settings, which does not apply to RAW files. Standard JPEG image files are processed and compressed, resulting in a loss of some image data, which does not align with the unprocessed nature of RAW files. Therefore, the defining characteristic of a RAW file format is its unprocessed state, allowing for maximum flexibility in editing and preservation of image quality.
