Apply a postcrop vignetteTo 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.
- 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.
- 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 grainThe 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.  No grain applied (top); grain applied (bottom). - Amount
- Controls the amount of grain applied to the image. Drag to
the right to increase the amount. Set to zero to disable grain.
- Size
- Controls grain particle size. At sizes of 25 or greater,
blue is added to make the effect look better with noise reduction.
- Roughness
- Controls the regularity of the grain. Drag to the left to
make the grain more uniform; drag to the right to make the grain
more uneven.
