Judging the effect
As you’re applying the tilt-shift effect in Camera Raw, you can enjoy using non-destructive blur effects. This enables you to fine-tune your tilt-shift effect to perfection. Click on a Graduated Filter’s control points at any time and drag them to change the strength and location of the blurred area. You can also click the Adjustment Brush’s pin and experiment with less extreme Clarity or Sharpness settings in the Adjustment Brush panel.
