Landscape photography is another common application for this technique. Colorful leaves in an otherwise drab scene can breathe life into a photo. Of course the technique can be applied to any genre, but portraits and landscapes are the usual beneficiaries.
More recently, films such as Schindler's List and Sin City (film) have made use of the technique. Schindler's List is a Biographical film directed by Steven Spielberg and written by Steven Zaillian. Sin City is a 2005 film written produced and directed by Frank Miller and Robert Rodriguez.
Selective coloring is generally regarded as cheap or tacky by higher end clientèle and professional photographers.
