Adjustment tools.

Fine tune and manually adjust your image with global or selective adjustments to get the exact result you are looking for. Start with a Preset , then make selective adjustments or begin in the Adjust Panel to take full control over your image with hundreds of powerful options available.

Noise Reduction.

Digital noise most often is classified as either Color noise or Luminance (light) noise. This noise shows up as color or light speckles in your image, often most visible in non-textured (smooth) areas. Noiseless provides control over each type of noise as well as special controls over smooth areas.

Color. Reduces color noise in the image. Moving the Amount slider to the right increases the amount of noise reduction. Moving the Smooth slider to the right adds additional color noise reduction on smooth surfaces.

Luminance. Reduces light noise in the images. Moving the Coarse slider targets light noise patterns in the image to keep details. Moving the Fine slider cleans light noise in smooth areas.

Smoothing. Sometimes noise patterns can form patterns in an image and this becomes especially visible in smooth surfaces. Increasing the Area slider applies the Color and Luminance noise reduction set previously to larger non-textured areas. The Strength slider increases or decreases the amount of Color and Luminance noise reduction applied to the smooth area.

Structure.

Reducing noise in photos has typically meant “softening” the image so that the noise and details making up the image are blurred, giving the illusion of noise removal. Noiseless solves that challenge using proprietary detail enhancement technology.

The Structure control will find edges and avoids adding contrast to edges but rather affects surface areas between edges. Introducing Structure will produce an increase of perceived texture. Removing Structure decreases perceived texture.

Amount - Controls the amount of Structure that is applied to the image or decreased.
Radius
- Controls the size of the surface areas and edges affected by Structure.
Protection
- Removes the effect of the Structure amount slider from the bright values of an image.

Details.

The Detail control is not present in the standard version of Noiseless, only in Noiseless CK. It is designed to retain edge detail in your image that might otherwise be softened by aggressive use of noise reduction. It’s a nice complement to de-noising that results in a naturally crisp look.

Amount - Controls the overall strength of the effect.
Protection - Removes the effect of the Detail slider from the bright values of an image.
Masking - The dynamic masking feature allows you to reveal details only in important areas and can also help to fight noise or halos in your skies. In effect, it protects the smooth areas of your image.

Filter.

After applying Noise Reduction and Structure & Details as part of a top-to-bottom workflow, it can be helpful to lessen those effects based on tonal range.

Highlights - Noise control of the brighter values in the image, basically affecting the tones on the right side of the histogram independently from the darker values.
Midtones - Noise control of the tones lying within the middle of the histogram.
Shadows - Noise control of the darker values in the image, basically affects the tones on the left side of the histogram independently from the brighter values.
Details - After decreasing the strength of previous adjustments, this slider allows you to re-introduce detail into the image.

Opacity. Decrease the overall filter effects on the image
