It was 20 years today, Photoshop taught the band to play...
Photoshop really was first marketed in February 1990. The Sgt.'s Pepper in those days were brothers Thomas and John Knoll. Thomas remained among the Photoshop developers until the current version, CS4. John moved into graphic effects in the movie industry, says Wikipedia.
Whatever advantages Potoshop has given us, even Lars van den Brink, a photographer who likes to play with Photoshop to tell his stories ("Sometimes, it's like I summarise an hour in a single picture"), and who was interviewed for the NRC's Cultural supplement last Friday, admits in the end: "Real life is so surprising; you cannot beat that with Photoshop."
That's a quote I like!
