Black & White, Monochrome or Duotone?
March 3, 2011
Post & Photo by Joe Farace
In the world of four-color (Cyan, Magenta, Yellow and black aka CMYK) printing, duotone is the name given the process of multiple tone printing using two, three or four different color inks. This process requires the press be set up with special inks instead of the standard CMYK inks that are used for four-color printing. Typically the paper is first printed using a dark base color and then a second lighter color is overprinted to fill in, tint, and tone the photograph and, more importantly, add depth. When two colors of inks are used it’s call duotone, when three inks are used it’s a tritone, and when four are used it is a quadtone.
Probably the most sophisticated way to achieve great tints in your monochrome pictures is to use the Duotones feature. Convert your image to Greyscale – Image > Mode > Greyscale, then convert it to Duotone – Image > Mode > Duotone. You can only convert a Greyscale image to Duotone. A Duotone palette opens, from here you can select Monotone, Duotone, Tritone, or Quadtone. Select Tritone and then click the Load button, this should take you into a set of preset values supplied with Photoshop. Navigate your way to the Presets Duotones/Tritones/ Pantone Tritones folder and select the Bl 172 orange Bl 423 grey file. On the left side of the palette are a set of curves, click on one to open up the Curve for the corresponding colour and adjust to taste, click on the colour swatch to change the colour – remember to keep the lightest colours at the bottom.
A duotone is a type of image which is printed in two colors. Duotones have been in existence since the early days of photography: most consumers are familiar with sepia toned prints, for example, which use various shades of brown. A duotone is also called a monochrome print, because the image appears to be comprised of variants on a single color.
The look of a duotone is favored over plain black and white photography in some cases because the duotone has a more saturated, compelling appearance.
Compare the color image in this series to the other two images. One is a grayscale image. The much more dramatic image is an infrared image.
Several compact digital cameras offer an IR effect, and several Photoshop plug-ins offer an IR filter, including nik’s Color Efex Pro mentioned above. Personally, I believe the most realistic IR images are produced by IR-only cameras that have been converted by the IR Guy (www.irdigital.net).
How to Select the Best “film” for a Specific Image
with both Film and Digital Capture
The first thing to keep in mind about film choice (or raw converter choices as we will see in a short while) is that these choices start with seeing. Photography is about seeing, as I explained in the first article in this series. All the articles in this series are not only related to each other but related to seeing as well.
What you see before you take a photograph influences all the decisions you will take later on regarding this photograph. In regards to film choice you need to ask yourself:
— do I see this scene in color or in black and white?
— if I see this scene in color do I see it with low saturation or high saturation?
— if I see this scene in black and white do I see it with high contrast or low contrast?
— if I see this scene in black and white do I see it as straight black and white or as a sepia (or other tone) print?
8 — Duotones, tritones and quadritones
I also encourage you to explore the alternative to pure black and white offered by Photoshop. Namely: duotones, tritones and quadritones. These are images in which more than one tone of ink is used to create a subtle hint of color. In pure black and white, and when printing with ink, only black ink is used, either pure black or different shades of black and light black. In duotones, tritones and quadritones, Medium gray may be replaced with magenta and white may be replaced with yellow, resulting in a sepia image. In a duotone, two colors of ink are used. In tritones a third color is added and in quadritones a fourth one as well. The combinations are endless and open a wide field of experimentation for creative endeavors. This is certainly an area worth exploring if you are so inclined. A set of predefined duotone, tritone and quadritone curves is provided with Photoshop. You can alter each of these curves to your liking and create your own set of curves. Sepia is only one of many possibilities.
