To fully control where a viewer's attention is drawn to on a photo, highlight the subject of the image. Some filters that create a vignetting effect help you achieve that purpose. However, such filters require the main subject to be in the center of the photo.
Radial filters in Adobe Camera Raw 8.0 direct attention to specific portions of the image. For example, you can use the Radial Filter tool to draw an elliptical shape around the subject, and increase the exposure and clarity of the area within the shape to bring more attention to the subject. The subject can be off-center, or anywhere in the photograph.
This is the main workflow to modify a photo with Radial filters:
- Open a photo in Adobe Camera Raw.
- Identify one or more areas where you'd like to attract the viewer's attention.
- Set up:
- (Optional) A Radial filter to weaken focus on the background
- A Radial filter to highlight the subject
- Additional Radial filters, if you have more than one subject to highlight
Do one of the following:
- To create a Radial filter, click and drag across the region, and draw a circular or elliptical shape. This shape determines the area affected or excluded from the alterations you are about to perform.
- To edit a Radial filter, click any of the gray handles on the photo. When selected, the handle turns red.
Adjust the size (width and height) and orientation of the Radial filter added. Select a filter and:
- Click and drag the center of the filter to move and reposition it.
- Hover the pointer over any of the four filter handles, and when the pointer icon changes, click and drag to change the size of the filter.
- Hover the pointer close to the edge of the filter, and when the pointer icon changes, click and drag the edge of the filter to change the orientation.
Use the Mask option to enable mask visualization. Alternatively, press Y to toggle the Mask setting.
For more information, see The Radial Filter in Camera Raw in Photoshop CC.
You can modify Radial Filter masks using brush controls. Once you've added a mask, to access brush controls, select the Brush option next to New/Edit. Alternatively, press Shift+K.
As appropriate, use the + and – brushes.
