Chapter 5: Develop Mode

Luminance

Drag the slider to the right to reduce the visibility of lighting noise. Apply a setting that is proportional to the

noise in the image and refer to the preview window to ensure that you balance the level of noise reduction with

loss of detail. Hold down the ALT key while using the slider to see the remaining noise in the image.

Strength

Drag the slider to the right to control how aggressively to reduce noise. Prevent the loss of detail by balancing

Luminance with Strength.

Color

Drag the slider to the right to remove color noise from the image. Hold down the ALT key while using the slider

to see the remaining color noise in the image.

View the effects of your changes in the Preview Window, located at the top of the Detail pane. Move the overlay square on

your image to change the area the Preview Window displays.

Correcting Chromatic Aberration

Chromatic aberration is a lens artifact that can result in fringes in high contrast areas of some photos. The camera lens can cause

different wavelengths of light to focus differently, which appears in photos as colored fringing or colored lines on the borders of

high contrast areas. Purple fringing can also occur when there is a bright spot of light in front of the lens.

This zoomed-in image shows an example of blue/yellow fringing.

You can use the Defringe and Chromatic Aberration tools in Develop mode to reduce the appearance of colored fringes. This can be

especially useful for photos with architectural details. For best results, it's recommended that you use the Chromatic Aberration

sliders first, and then the Defringe sliders.

You can save your settings as a preset for future use.

To reduce fringing in your image:

1. In Develop mode, select the Detail tab.

2. In the Chromatic Aberration group, adjust the sliders as described below.

You can right-click a slider to reset to the default value.
