Vignette, grain, and dehaze effects in Camera Raw

The Grain section of the Effects tab has controls for simulating film grain for a stylistic effect reminiscent of particular film stocks. You can also use the Grain effect to mask enlargement artifacts when making large prints.

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.

Controls the amount of grain applied to the image. Drag to the right to increase the amount. Set to zero to disable grain.

Controls grain particle size. Specifying a value of 25% or higher can cause some image blurring.

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.

Apply a postcrop vignette

To apply a vignette to a cropped image for artistic effect, use the Post Crop Vignetting feature.

Dehaze

Adobe Camera Raw allows you to easily decrease or increase the amount of haze or fog in a photograph. Click  in the Adjustment panel on the right to view the Basic panel and adjust the Dehaze slider control.

Controls the amount of haze in a photograph. Drag to the right to remove haze; drag to the left to add haze.

Radial filters in Adobe Camera Raw direct attention to specific portions of the image. To know more, see Radial Filter in Camera Raw.
