Apply a postcrop vignette
To apply a dark or light vignette for artistic effect to a photo, use the Post-Crop options in the Vignettes panel.
Applying a postcrop vignette adds black or white values to the edges of the photo. A postcrop vignette can be applied
to a cropped or uncropped photo.
1
In the Post-Crop area of the Vignettes panel of the Develop module, move the Amount slider to the right (positive
values) to lighten the corners of the cropped photo. Move the slider to the left (negative values) to darken the
corners of the photo.
2
Move the Midpoint slider to the left (lower value) to apply the Amount adjustment to a larger area away from the
corners. Move the slider to the right (higher value) to restrict the adjustment to an area closer to the corners.
3
Move the Roundness slider to the left (lower value) to make the vignette effect more oval. Move the slider to the
right (higher value) to make the vignette effect more circular.
4
Move the Feather slider to the left (lower value) to reduce softening between the vignette and its surrounding pixels.
Move the slider to the right (higher value) to increase the softening between the vignette and its surrounding pixels.

Reduce image noise
Image noise is extraneous visible artifacts that degrade image quality. Image noise includes luminance (grayscale)
noise, which makes an image look grainy, and chroma (color) noise, which is usually visible as colored artifacts in the
image. Photos taken with high ISO speeds or less-sophisticated digital cameras can have noticeable noise.
Moving the Noise Reduction Luminance slider to the right reduces grayscale noise (upper right), and moving the Noise Reduction Color slider
to the right reduces chroma noise (lower right).
1
(Optional) Zoom in on the photo to at least 1:1 to better see image noise and the effects of the sliders.
