Many years ago a controversy over colorization of classic movies erupted. Movies such as Miracle on 34 Street and It’s A Wonderful Life were colorized. Did it ruin or improve the movie? Well depends on your perspective. Some movies were designed to take advantage of black and white and loose some of their character when colorized. It is not an easy thing to do to put color in and make it look natural. Some movies look odd as a result. Miracle on 34 Street is pretty good and the Santa suit (the one the toy manager compliments Kris on) really looks good. Anton Logvynenko decided to use modern technology to render Titanic photos in color.
And the result is nothing less than spectacular. Images most everyone has seen of Titanic now have crisp color to them. It is remarkable what he has done. You can view his work at Titanic In Color.
