Once you have measured the noise inherent to your image,

it is time to start reducing noise. You can choose from one

of two methods to reduce noise globally or selectively,

based on colors or objects found within your image.

Control Points

The ﬁrst method of applying noise reduction within Dﬁne

2.0, Control Points, is based on U Point technology. Each

Control Point can control the amount of Contrast and Color

noise reduction to apply to the object that it has selected.

In this manner, you can quickly add Control Points and then

indicate whether or not to apply Contrast or Color noise

reduction to each object, and how much to apply.

You can also control the amount of noise reduction applied

to the entire image using the global Contrast and Color

noise reduction sliders in the Control Points method

Color Ranges

The second method of reducing noise within Dﬁne 2.0 is

based on individual Color Ranges. This method is most

effective when affecting large objects or if you want to

uniformly reduce noise based on color.

Additional Controls Available for Each Reduction Method

Edge Preservation

This control lets you balance detail and noise reduction.

JPEG Artifact Reduction

This control reduces JPEG artifacts in the active image. (Use only on JPEG ﬁles.)

Debanding

The debanding control reduces banding artifacts, which appear as bands across an image.

Dﬁne 2.0 Noise Reduction Workﬂow

Select Dﬁne 2.0 from the Filter menu or the Selective Tool.

1. Measure the noise in the image with the different measuring methods.

2. Reduce noise using U Point powered Control Points, to selectively control

the noise reduction if desired.

3. Review the image in the Loupe.

4. Apply the ﬁlter.
