Enhancing photos selectively with Tintii
Tintii, a modest image-processing program, transforms color images into black-and-white pictures then enhances specific areas with eye-catching colorizing effects.
Important objects can be highlighted in a picture by blurring the background, cutting out the subject, removing the color from unimportant areas, or adding color to important features. An example of the last variation is Schindler’s List , filmed by Steven Spielberg entirely in black and white, except for one scene showing a child wearing a bright red coat in the otherwise monochrome shot. A similar technique was used in the film Pleasantville  by removing color, then adding it back in selectively.
