One of the colorists is a very young woman from Brazil named Marina Amaral. In my opinion she is the best out there.
I know how to restore antique / vintage photos like she does. But what she can do with color is amazing.
She recently colorized a number of Auschwitz photos of children which were astounding.
I follow her on Twitter and always look forward to her updates. She does work for people who want their family photos restored and colored.
Interesting to see these old photos colorized. Ive seen others of old New York. It definitely gives the images far more life.
