alt Hacker NewsGrayscale cameras are not that much cheaper than color cameras. And if you decided to use a grayscale camera on purpose, you probably do not care about the color information (which would be totally "made up" by the colorizing algorithm).
Also, if there are only grayscale photos of you, you were probably born before 1900, and all your friends or your children (who might want to colorize your photo) are probably dead, too.
What does the existence of a color photograph of my grandmother as an old woman have to do with my desire to colorize a grayscale photo of her as a child? Or colorize the photos of her wedding?
It's a very strange argument to make: there exist some photos therefore other photos may not be colorized!
