Add and edit images
You can add photos and graphics to any sheet, then change their appearance in a number of ways.
Numbers provides many predesigned image styles—which include coordinating borders, reflections, and shadows—that are designed to match a spreadsheet’s template. You can quickly edit an image by applying one of these styles to it, or you can customize its appearance by applying your own border, shadow, and more. You can also crop an image by masking out parts you don’t want, and make adjustments to its background and exposure.
Add an image
To add an image, do any of the following:
Click Media in the toolbar, then select an image from your Aperture or iPhoto library. Drag the image to the sheet.
Drag an image from the Finder, or from a webpage, to the sheet.
Choose Insert > Choose (from the Insert menu at the top of your computer screen), then select an image to add it.
Click in the bottom-right corner of an image placeholder, then select the image you want to add.
Image placeholders are used in templates to give you examples of object spacing and layout.
Mask (crop) a photo
You can hide unwanted portions of an image without cropping the image itself. Use the mask controls to frame just the parts of the image you want to be visible.
Double-click the image.
The mask controls appear. The default mask is the same size as your image.
Use the controls to change which parts of the image are visible.
You can change the mask at any time by double-clicking the image to reveal the controls. Or, you can select the image, then click Edit Mask in the Image pane of the Format inspector.
Remove background and other elements from a photo
Use the Instant Alpha tool to make parts of an image transparent. This feature is useful for removing an unwanted background or color from an image.
Select the image.
In the Image pane of the Format inspector, click Instant Alpha.
Click the color you want to remove, then drag slowly over it.
As you drag, the selection grows to include areas that use similar colors. Click and drag multiple times to remove multiple colors.
Remove all instances of the color (even in other parts of the photo): Hold down the Option key while you drag.
Add colors back to the image: Hold down the Shift key while you drag.
Adjust exposure, saturation, and other image settings
Select the image.
In the Image pane of the Format inspector, use the controls to make adjustments:
Exposure: Changes the overall lightness or darkness of the entire image.
Saturation: Changes the richness of color in the image. Dragging to the right makes the colors richer or more vibrant.
Enhance: Automatically adjusts the image by spreading the red, green, and blue tones evenly across the histogram.
To see the image histogram and adjust more advanced features like levels, gamma, temperature, and tint, click .
To restore the original settings, click Reset Image.
