Step 3 Go to Layer > New Adjustment Layer > Levels and reduce the black output level to 42. The idea here is to drop the contrast to give that washed-out look.
Step 4 Go to Layer > New Adjustment Layer > Color Balance. In Midtones, change the value for the magenta-green to -8. For the Shadows, change the three values to +25, -2 and -11, and the Highlights to +12, -21 and -25. Note that you’ve increased the red and magenta values, giving a warmer cast to the image.
Step 5 We don’t want the whole image to look this warm and bright; more contrast will make it look more dynamic. We’ll first dull it down and then bring some contrast back. Go to Layer > New Adjustment Layer > Hue/Saturation and change the Hue to 28, the Saturation to 37 and the Lightness to -10. Check the Colorize tickbox too.
