Of course I didn’t take these photographs. But I did color, or rather, colorize them. In most cases, I didn’t color parts of the image individually, but mapped colors to tonal values. Put more simply I mapped different colors to differing shades of of light and darkness in the black and white photos.
At times I cheated a little and actually “colored” – Josephine Bakers’ lips, for example. Flag & Gun Girl, if I recall correctly, was a color photograph so faded that it was nearly black and white. I think most of the others were all black and white.
These should all be fair use. I’m in the process of researching to determine the proper copyright owner if not public domain. I retain copyright for the particular colorization as derivative artwork.
