Photography has undergone a massive change in the last decade or so as it embraces the digital medium almost completely. People take more mangakalot photographs than ever before and most of them will only ever be displayed on a screen. The most common format for storing images is the JPEG format. Anyone anywhere can store a photo in this format and be sure that it will be displayed on the internet correctly as well as work with almost every photo editing software out there.
However, this format is not without its disadvantages. The biggest one being that every time the image is opened, edited and saved, it gets compressed and loses a bit of its quality. Ordinarily, this compression is an advantage as it keeps the file sizes low, but in certain situations you want to use the best possible quality available. Such situations demand the use of some different formats.
