Converting a digital color photo into black and white goes beyond simply desaturating the colors, and can be made to mimic any of a wide range of looks created by using color filters in black and white film photography.

Converting a Digital Color Photo into Black and White

Conversion which does not take into account an image's color and subject of interest can dilute the artistic message, and may create an image which appears washed out or lacks tonal range. This section provides a background on using color filters, and outlines several different black and white conversion techniques — comparing each in terms of their flexibility and ease of use. Contrary to what one might initially assume, traditional black and white photographers actually have to be quite attentive to the type and distribution of color in their subject. Color filters are often used in front of the lens to selectively block some colors while passing others (similar to how color filters are used for each pixel in a digital camera's bayer array).
