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.

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. Specifying a value of 25% or higher may cause some image blurring.

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.

  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.

    Paint Overlay

    Applies the postcrop vignette by blending original image colors with black or white. Appropriate when a soft effect is desired but may reduce highlight contrast.

  3. Refine the effect by adjusting any of the following sliders:

    Amount

    Positive values lighten the corners, negative values darken them.

    Midpoint

    Higher values restrict the adjustment to the area closer to the corners, lower values apply the adjustment to a larger area away from the corners.

    Roundness

    Positive values make the effect more circular, negative values make the effect more oval.

    Feather

    Higher values increase the softening between the effect and its surrounding pixels, lower values reduce the softening between the effect and its surrounding pixels.

    Highlights

    (Available for a Highlight Priority or Color Priority effect when Amount is a negative value) Controls the degree of highlight “punch” in bright areas of an image, such as in the glow of a streetlight or other bright light source.

Dehaze

Adobe Camere Raw now lets you easily decrease or increase the amount of haze or fog in a photograph. Once you have made basic adjustments to the photograph, switch to the Effects panel and adjust the Dehaze slider control.

Adjust the Dehaze slider control

Amount

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

Radial Filter

Radial filters in Adobe Camera Raw direct attention to specific portions of the image. See, Radial Filter in Camera Raw.

Note: Dehaze is now available as a local adjustment. While working with the Radial Filter, Graduated Filter, or the Adjustment Brush, adjust the Dehaze slider control. For more information, see Make local adjustments in Camera Raw.
