.RAW
A .RAW file is an unprocessed, raw form of a digital image file. It is a file format used in digital photography and stores the raw sensor data captured by a digital camera. Unlike other common image formats such as JPEG, TIFF or PNG, a RAW file is not compressed and contains all the raw data captured by the camera without any processing or compression.
The main feature of a RAW file is that it offers photographers a greater degree of control and flexibility when editing their photos. Because it contains all the original data, photographers can adjust exposure, white balance, color correction and other settings afterwards without losing quality. This makes it a valuable format for professional photographers and serious amateurs who want to edit their images in minute detail.
Disadvantages of the RAW file format in digital photography
The disadvantage of RAW files is that they are generally larger than compressed formats such as JPEG, so they take up more storage space. In addition, they cannot be displayed directly in many standard image viewing programs and require special software for viewing and editing. It is generally recommended that you shoot in RAW if you plan to perform extensive post-processing, but it can be convenient to also save a JPEG version of your photos for quick viewing and sharing.
