Let’s take a look at several eras in computing that have driven the use of images to new levels.
This is the third post in a set of four which outline the nature of images, formats and applications. As the complexity of digital images has grown, new formats have appeared to enable these capabilities. In fact, formats have always largely been purpose-driven. They are created as standardized containers that facilitate saving particular types of
