Which is better, TIF format or RAW format?

TIFF is an uncompressed bitmap that supports multiple layers. After processing by the camera graphics processor, the image quality is the best in the bitmap.

RAW is not an image format. It is the original record of data from photosensitive elements, which has not been processed by graphics processor. It is the most original data and can provide the best adjustment scheme for photographers.

These two have their own advantages. TIFF can be used directly, of course, it can also be pressed into JPEG later, and RAW must be processed into a general image processing format that can be spread through PC.
