12. Click the assassin layer at the very bottom of the layer stack, and then add a Hue/
Saturation adjustment layer. Lower Saturation to -85 so that the model matches the
background more closely.
Note
The assassin layer is a Smart Object, so we could lower the saturation of the
model by double-clicking the thumbnail and going into the Camera Raw filter. We
used a Hue/Saturation adjustment instead so that it would be easier to judge how
much the saturation needed to be lowered. I did not want to remove the color
completely.
Add a Moveable Vignette
Now we'll darken the area around the model with a vignette. This technique creates a
moveable vignette that we can reposition at any stage.
1. Click the background scene group at the top of the layer stack, and add a Levels
adjustment layer. Drag the midtone point to 0.30 ( Figure 11.52 ) so that the entire
image is darkened.
