The difference between RAW format and TIFF format:
1. TIFF is a lossless compression format, while RAW is simply the original unprocessed format;
2 , TIFF can be opened by general software, but RAW can generally be opened by the software provided with the machine. RAW contains more information than TIFF;
3. TIFF cannot be exposed, while RAW cannot be opened. Exposure adjustment can be performed;
4. TIFF tone exposure may be lossy, but RAW tone exposure is lossless.
First, TIFF is a photo format, that is, Tagged Image File Format (TIFF). It is a flexible bitmap format mainly used to store photos and artistic images. images included. It was originally developed by Aldus Corporation in conjunction with Microsoft Corporation for PostScript printing. TIFF joins JPEG and PNG as a popular high-bit color image format. The TIFF format is widely supported in the industry, such as Adobe's Photoshop, The GIMP Team's GIMP, image processing applications such as Ulead PhotoImpact and Paint Shop Pro, desktop printing and page layout applications such as QuarkXPress and Adobe InDesign, scanning, faxing, Word processing, optical character recognition, and other applications support this format. Adobe, which acquired the PageMaker printing application from Aldus, now controls the TIFF specification;
2. The original meaning of RAW is "unprocessed". It can be understood that a RAW image is the raw data in which a CMOS or CCD image sensor converts the captured light source signal into a digital signal. RAW files are files that record the original information of a digital camera sensor, as well as some metadata (Metadata, such as ISO settings, shutter speed, aperture value, white balance, etc.) generated by the camera shooting. RAW is an unprocessed and uncompressed format. RAW can be conceptualized as "original image encoded data" or more vividly as "digital negative". The full name of RAW format is RAW Image Format, which is called original in programming.
