The ISO arithmetic speed has a useful property for photographers without the equipment for taking a metered light reading. Correct exposure will usually be achieved for a frontlighted scene in bright sun if the aperture of the lens is set to f/16 and the shutter speed is the reciprocal of the ISO film speed (e.g. 1/100 second for 100 ISO film).

Shortly afterwards, a minor revision was published — JFIF 1.01. [3] For nearly 20 years, the latest version available was v1.02, published September 1, 1992. [2] In 1996, RFC 2046 specified that the image format used for transmitting JPEG images across the Internet should be JFIF. The MIME type of "image/jpeg" must be encoded as JFIF.
In 2019, libjpeg-turbo became the ISO and ITU endorsed reference implementation for the JPEG format. [ 14 ] In April 2024, Google introduced Jpegli , a new JPEG coding library that offers enhanced capabilities and a 35% compression ratio improvement at high quality compression settings, while the coding speed is comparable with MozJPEG.

Adobe's DNG SDK provides a software library for encoding and decoding lossless JPEG with up to 16 bits per sample. ISO/IEC Joint Photography Experts Group maintains a reference software implementation which can encode both base JPEG (ISO/IEC 10918-1 and 18477-1) and JPEG XT extensions (ISO/IEC 18477 Parts 2 and 6-9), as well as JPEG LS (ISO/IEC ...
