Vignette, grain, and dehaze effects
Apply a postcrop vignette
To apply a dark or light vignette for artistic effect to a photo, use the Post-Crop Vignetting options in the Effects panel.
A postcrop vignette can be applied to a cropped or uncropped photo.
Lightroom postcrop vignette styles adaptively adjust the exposure of the cropped image, preserving the original image
contrast and creating a more visually pleasing effect.
1 In the Post-Crop Vignetting area of the Effects panel of the Develop module, choose an option from the Style menu:
Highlight Priority Enables highlight recovery but can lead to color shifts in darkened areas of a photo. Suitable for
photos with bright image areas such as clipped specular highlights.
Color Priority Minimizes color shifts in darkened areas of a photo but cannot perform highlight recovery.
Paint Overlay Mixes the cropped image values with black or white pixels. Can result in a flat appearance.
2 Adjust the sliders:
Amount Negative values darken the corners of the photo. Positive values lighten the corners.
Midpoint Lower values apply the Amount adjustment to a larger area away from the corners. Higher values restrict
the adjustment to an area closer to the corners.
Roundness Lower values make the vignette effect more oval. Higher values make the vignette effect more circular.
Feather Lower values reduce softening between the vignette and the vignette’s surrounding pixels. Higher values
increase the softening.
Highlights (Highlight Priority and Color Priority only) Controls the degree of highlight contrast preserved when
Amount is negative. Suitable for photos with small highlights, such as candles and lamps.

Simulate film grain
The Grain section of the Effects panel has controls for creating a stylistic effect reminiscent of particular film stocks.
You can also use the Grain effect to mask resampling artifacts.
Together, the Size and Roughness controls determine the character of the grain. Check grain at varying zoom levels to
ensure that the character appears as desired.
