18-year-old Artist Mads Madsen has an amazing skill for colorizing old black and white photographs. Even beside their original counterpart the results are impressive, bringing a new dimension of realism to historic images. An American Civil War buff, Madsen’s 450+ portfolio of images can be seen on minus.com.

Madsen says it takes him about 20-30 minutes for a portrait but that the outdoor shots and images with lots of people and background take substantially longer. For a video tutorial of the process involved, you can check him out on YouTube.
