Here's a black and white photo of Mom (right) with her older sister, my Aunt Jean. It was taken sometime in the 1950s at the farm near Virden, Manitoba. Jason Antic's image colourization software. Colourizing black and white imagery is nothing new, of course, but I'm pretty impressed by the results given how easy it is to use the software; just upload your photo and the algorithm spits out its best guess.
And here they are in colour.
Say what you will about the wisdom of colourization, but for all its flaws I find the process fascinating, and I imagine the colours will achieve greater fidelity and believability as the technology improves.
