Using the Effects tab

In traditional photography, the faster the film speed, the larger and more apparent the grain. As an intentional effect, you can simulate this grainy texture via the Grain controls in Camera Raw. Choose a photo that won’t suffer aesthetically when its details lose definition.

To add a grain texture to a photo:

  1. Click the Effects tab, c0084-01.jpg and double-click the Hand tool c0057-02.jpg to fit the image in the preview. A

    A This photo is a good candidate for the Grain effect because we won’t mind if the details are softened and it contains muted colors.

  2. To create a noticeable grain, under Grain, choose an Amount value of around 50.
  3. To emulate the fine grain of slow film or the coarse grain of fast film, do as follows:

    Set the Size value for the size of the grain particles. B When this value is greater than 25, a small degree of blurring is also applied, to help blend the grain with the imagery.

    B The first settings we chose were Grain Amount 50 and Size 80 (we left the Roughness control at the default value of 50). The food textures are beginning to blend with the soft background.

    Reduce the Roughness value below the default value of 50 for a more uniform grain, or increase it for an uneven, coarse grain. C Zoom in to examine the grain, then readjust the Amount value, if needed.

    C We increased the Amount to 75, the Size to 60, and the Roughness to 65. The coarser grain unifies the highlights and background with the food textures even more. Please pass the Parmesan…

Using the Post Crop Vignetting controls, you can apply a light or dark vignette to a photo (lighten or darken the outer areas). If you crop the photo subsequently in Camera Raw, the vignette will reconform to the new dimensions.

To apply a vignette to a photo:

  1. Click the Effects tab, c0084-01.jpg and double-click the Hand tool c0057-02.jpg to fit the image in the preview. A

    C We lowered the Midpoint value and raised the Feather and Highlights values.

    D When we cropped the image, the vignette readjusted automatically.

    Choose Style: Highlight Priority.

    Choose a negative Amount value for a dark vignette or a positive value for a light vignette.

    Adjust the Midpoint value to expand the vignette inward or outward.

    Adjust the Roundness value to make the vignette shape more oval or more like a rounded rectangle.

    Adjust the Feather setting to control the softness of the transition to the nonvignetted areas.

    Adjust the Highlights setting to control the brightness of the highlights within the vignette area.
