A Duotone image is basically a monochrome photo that has another colour, or sometimes more in the shadows, highlights or midtones. It's an easy process that gives quick and interesting results.
Step 1: Turn your image to greyscale
To start you need to convert your coloured inmage to Greyscale by going to Image>Mode>Grayscale.
Step 2: Duotone
Your image should now be black & white. To add the colour you need to go to Image>Mode>Duotone. When the new window opens change the Type drop down menu to Duotone to give you two Ink boxes to work with. Unless you're creating an abstract image keep the first Ink box as black and click on the second box to select a colour you want to use. If the preview box is ticked your image will change as you cycle through the colours. Once you're happy click OK and you have your Duotone image.
