I must live up to my url and offer how to tips. This is the first in a series of tutorials (see video below).
For my Digital Color Theory class at Colorado Mountain College, I had to create a duotone image. According to wikipedia.org, a duotone is “a halftone reproduction of an image using the superimposition of one contrasting color halftone (traditionally black) over another color halftone.” If you are not a graphic design or photography whiz, this probably sounds oogli-boogli. A simple way of thinking about duotones is to breakdown the word, which literally means two colors (tones). Essentially, a duotone photograph uses only two colors. Here is an example:
The only colors used in this photo are blue and black. By using software such as Photoshop, you can assign colors to tones (blue to lighter tones, black to darker tones) in a black and white photograph. Instead of being a black and white photograph, more accurately, this picture is now a black and blue photograph. This can be done to create subtle “cooling” or “warming” effects, and it can also be used for more extreme, illustrative-like effects. Here is a before and after duotone:
I’ve always seen duotones but have never understood how they are made…until now. Learn for yourself:
