RAW files are approximately how much of the file size of a non-compressed TIF image?

RAW files are often larger than non-compressed TIFF images due to the way they store data. Typically, a RAW file is designed to contain all the unprocessed image data captured by a camera sensor, which includes a greater bit-depth and additional information for post-processing adjustments. A non-compressed TIFF image, while still high quality, represents a fully processed image that has undergone some form of compression or conversion, resulting in a smaller file size.

The estimate that RAW files are approximately 1.3 times the size of a non-compressed TIFF reflects the additional data and detail contained within the RAW format. This implies that while both formats maintain high image quality, the RAW file's capabilities for extensive editing and lack of compression contribute to its larger size compared to a TIFF file. This understanding is key for photographers who want to manage storage space effectively, especially when deciding how to save their images after shooting.
