Temperature: Changes the warmth or coolness of the image by adjusting the amount
of warm tones (red) or cold tones (blue).
Tint: Changes the overall color cast of the image by adjusting the amount of red or
green tones.
Sharpness: Sharpens or softens (blurs) the focus of the image.
Exposure: Changes the overall lightness or darkness of the entire image. When you
adjust exposure, every part of the image gets lighter or darker. Increasing the exposure
of an image can also reduce its color.
Histogram and Levels: Describes the total color information in the image, from the
darkest shadow on the left, to the brightest highlight on the right. The heights of the
peaks tell you how much color information falls in a given range.
To set the light level, drag the right slider toward the middle. Dragging the slider to
the left narrows the range of color and can bring more clarity to the highlights. The
position of the slider determines how much information is in the lightest part of the
image; any information to the right of the slider is omitted from the image. You may
want to drag the slider just to the point that the histogram line shows a noticeable
bump, signifying that detail is available.
To set the dark level, drag the left slider toward the middle. Dragging the slider to
the right narrows the range of color and can bring more clarity to the shadows. The
position of the slider determines how much information is in the darkest part of the
image; any information to the left of the slider is omitted from the image. You may
want to drag the slider just to the point that the histogram line shows a noticeable
bump, signifying that detail is available.
Enhance: Automatically adjusts the image by spreading the red, green, and blue tones
evenly across the histogram.

Creating Shapes
Pages provides a variety of predrawn shapes you can add to documents, including
circles, rectangles with square or rounded corners, stars, “speech bubbles,” arrows, and
more. You can also create your own custom shapes or alter the lines and contours of a
predrawn shape.
