duo tone

Duotone is a image made up of only two images (traditionally black and another colour). Normally used to bring out middle tones and highlights of an image, most common colours that are used are blue, yellow, browns and reds. Now because of digital manipulation programs such as photoshop, duotones, tritones and quadtones can be very easily created.
To create this image I used the presets that are on the duo tone.

Click on the colour box to decide what colour and shade you want .

Add more colours to create a tritone or quadtone.

Next to the colour box there is a graph click on this if you want to change the contrast of that colour.
