How to: Use Selective Colour in Photos

1 Adjust a colour channel

Open a photo with greenery and a sky in the Photos edit view. Scroll down to Selective Colour. Select the green colour channel, and drag Hue all the way to the left. Notice how this shifts the greens towards red, making for an autumnal look.

2 Amend the range

Use the Range slider to adjust the range of colours over which your adjustment is applied. Nudge it left to soften the effect, or right to increase it. Experiment with Saturation to amend the intensity of the colour selection.

3 Use a custom hue

If you want to alter a specific colour, select it with the eyedropper tool, and then adjust settings accordingly. Click on the sky and maximise Hue for a freaky alien purple sky. (Perhaps be subtler on your own pics!)
