When it comes right down to it, do you know how a digital image works? Could you explain to a child how an image captured from the world can be digitally heightened or altered? Or how a computer-generated image is produced? Of course, you do not need to know. For all its advantages, the digital age has alienated us from the inner workings of everyday machines, devices and processes. Constructed digital images have come to look ordinary to us now, "the new normal." While most of us have played around with Instagram filters or Photoshop effects, a tiny minority understands the technology that underpins them. Research scientists in technology graphics labs are the high priests of our new visual reality. The keepers of the mysteries. The rest of us just sit back and let the images wash over us.
