I’ve known for years that there are numerous file types that you can use to Save / Output your Digital Artwork – all specifically engineered by Computer Programmers / Software Designers in consultation with Graphic Design / Photography Experts from all over the world to give the best Quality results when displaying / printing certain types of images. There are file types that should be used when you want to preserve all the Layers in an edit in case you want to re-edit it later and to avoid image compression / degradation to a certain degree. There are also file types that are best for outputting / displaying Graphics, or displaying Photographs.
The most widely used image file type is called a .jpg or JPEG and it was developed by the Joint Photographic Experts Group. It’s a form of Digital Image Compression that was created to enable Web Page load times to be kept to a minimum. But the fact that JPEG Compression discards digital information to minimize file sizes and produce images of an ” acceptable ” visual quality for display on the web means that there is a certain degree of spoiling or degradation that occurs as a result.
I knew a lot of the critical facts when it comes to preserving as much image Quality as possible when working with .jpg image files, but I have recently found an extensive list of some facts that I wasn’t aware of until reading it. It’s a great Article – make sure to read the second page as well !
