Playing with Colorization

I’m trying out the colorization feature on Photoshop again, second attempt. Seems pretty banal, I’ll need to find its dials and get into the tweaking of it. For this exercise I scanned a copy of issue 32 and then added color to the original black and white image I’d shot of a Che Cafe show, then went back and flattened out the original into monochrome, then colorized that. Difficult to see much difference in the two colorizations but maybe there’s something I’m missing.

 

Again I’m curious to know how Photoshop knew what the original masthead color was red when I sent the black and whited version through. Maybe there was some sort of image rendering cookie function that memorized it beforehand. I don’t know. Too many questions.
