The difference between various picture formats

Introduction to JPEG format
The JPEG format is all called Joint photograhic experts Group, with the extension jpg. JPEG is a file compression format that provides excellent image quality, and the photos taken in JPEG format are processed through the image processor inside the camera and can be directly out of the picture. Although JPEG is a lossy compression format, in general, as long as the image is not the pursuit of too fine quality, JPEG has many advantages to consider, JPEG usually compression ratio between 10:1 to 40:1, so you can save a large portion of memory card space, which greatly increased the number of pictures taken, and speed up the photo storage speed, and also speed up the continuous shooting speed, so widely used in news photography. Tip For most users and the average family, JPEG files with low compression (high quality) are a good choice.

JPEG has a good advantage in remote transmission, in order not to affect the viewing of the naked eye please do not compress the ratio of less than 8, if it is LAN transmission, please use JPEG lossless compression () or directly with TIFF.

Note: generally speaking JPEG and JPG are the same thing

Introduction to the Tife format
Tife is all called tagged Image File Format, and the extension is TIF. TIFF is a non-distorted compression format (up to 2-3 times the compression ratio). This compression is the compression of the file itself, that is, some of the duplicated information in the file is recorded in a special way, the file can be completely restored, can maintain the original color and hierarchy, the advantage is good image quality, compatibility is higher than the raw format, but occupies a large space. For example, a digital SLR camera captures a 2 million-megapixel raw format image that takes up almost 6MB of capacity, so the TIFF format is typically used for more professional purposes, such as book publishing , poster printing, and so on, rarely used on the internet.
