Using the Color Meter and Displaying Camera Information
Aperture provides a built-in Color meter you can use to sample the color values in an
image and display them as RGB, Lab, CMYK, HSL, or HSB values. When you place the
pointer over an image or thumbnail, the color values are displayed in the Adjustments
inspector or the Adjustments pane of the Inspector HUD. You can also use the Loupe for
a more accurate pixel selection and see the color values displayed within the magnified
area of the Loupe. When the pointer is moved away from the image, the color values are
replaced by basic EXIF metadata values for the image, such as ISO setting, f-stop, shutter
speed, and focal length.
To display camera and color information
