What Does VGA Mean When Talking About Photography?
VGA or ‘Video Graphics Array’ refers to an image resolution size of 640 x 480 pixels (0.3MP) at an aspect ratio of 4:3. The use of VGA to describe a specific resolution began in the early 1990’s when VGA, or 640 x 480 resolution was the standard video resolution output of the graphics chips onboard many home PCs. VGA was superseded in around 1996 by SVGA, or ‘super video graphics array’ which features a resolution on 800 x 600. The VGA resolution is now extremely out of date, but serves as a useful landmark when considering exactly how far graphical imaging technology has progressed over the last 25 years.
