Simulate film grain
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.
For a video tutorial about using the Grain effect in Camera Raw, see The new Grain feature in CS5 by Matt Kloskowski or Black and white film
grain in Photoshop and Lightroom by Dan Moughamian.
No grain applied (top), grain effect 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, the image may appear slightly blurred.
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.
Apply a postcrop vignette
To apply a vignette to a cropped image for artistic effect, use the Post Crop Vignetting feature.
For a video tutorial about creating postcrop vignettes in Camera Raw, see Vignetting in Camera Raw CS5 by Matt Kloskowski.
1. Crop your image. See Crop images.
2. In the Post Crop Vignetting area of the Effects tab, choose a Style.
Highlight Priority Applies the postcrop vignette while protecting highlight contrast but may lead to color shifts in darkened areas of an
image. Appropriate for images with important highlight areas.
Color Priority Applies the postcrop vignette while preserving color hues but may lead to loss of detail in bright highlights.
