For example, in a photo where you want an otherwise too bright sky to have more blue, you can use a blue graduated filter to increase the blue of the sky without affecting the lower part of the photo. This lets you adjust the color in a specific area of the photo. Graduated filters often consist of a single color that fades to transparent. You can apply a color gradient to your photos to simulate the effect achieved by using a graduated filter on your camera lens.
