Mono images don’t just have to be grey. By adding a colour tint to your image, known as Duotoning, you can add another layer of mood to the photograph, whether it’s a warm, yellowy sepia look for a nostalgic feel or a blue to add coolness to the shot, for instance. Here’s how to create two popular duotones that you can then adapt if you wish.
SEPIA
With your image converted to mono along with any other adjustments to contrast applied, select the Hue/Saturation Adjustment icon and in the dialogue box, tick Colorize. From the Presets, select Sepia. At the moment, this is a little too intense, so we’ll reduce the Saturation to 18 and Lightness to +6.

CYANOTYPE
Just as with the Sepia toning effect, once you’ve converted your image to mono select the Hue/Saturation Adjustment icon and in the dialogue box, tick Colorize. This time from the Presets, select Cyanotype. Again, this is too intense, so knock back the Saturation to 12 and increase the Lightness to +7.
SPLIT TONING
Split-toning takes toning one stage
further, introducing an additional colour, and was a popular darkroom
technique. Thanks to a clever mix of processing chemicals, tones in the
image would literally be split, which would result in a colour shift in
the highlights and shadows.
One great way to achieve a split-tone effect with digital images is to create a Gradient Map. While this may sound like it’s quite complex, once you’ve created your first Gradient Map, it’s very easy and you’ll then be able to start creating your own split-tone mixes.
1 SELECT GRADIENT MAP
Once you’ve converted your image to mono, bring up your Layer palette (F7 ) and at the bottom, click on the Create new fill or adjustment layer icon at the bottom of the palette. From the drop-down menu, select Gradient Map.

2 MAKE A COLOR STOP
Click on the Gradient to bring up the Gradient Editor dialogue box. From the Presets, select Black, White. Click a quarter of the way along so the Location is 25% to create a Color Stop. Click on the Color, and pick a dark colour from the Color Picker and hit OK.

3 SAVE GRADIENT
Now click three-quarters along to add another Color Stop – Location should be about 75%. Click on the Color again and select a light tone for the highlights and hit OK. Now hit New to save the Gradient in the Presets so you can use the gradient on another image.

4 ADJUST OPACITY
The effect will probably look too strong, so – making sure you have the Gradient Map layer selected – we can use the Opacity control to vary the intensity of it, in this case taking it right back down to an Opacity of 20% to produce some subtle tones.
