Photoshop maestros give us a glimpse of how our vintage photography would look if they were taken in color.  Some of the more advanced digitizers find a known color in the photograph and use digital analysis of color values to determine the rest of the items.  Some use descriptions written about the image and others just make it up. Even if they are not 100% accurate, we enjoy seeing them in a new light.  We hope you do too.  Images via http://www.rsvlts.com/2012/08/10/adding-color-to-the-most-iconic-photos-in-history
