An Overview of the Viewer

When you select images in the Browser, the Viewer immediately displays a detailed view of your selection. You can display one image at a time, three images at a time, or any selection of multiple images.

When rating or adjusting images, you can set the Viewer to compare two images at once. You select an image to compare against and then display other similar or related images next to it for inspection. You might use the Aperture comparison feature to select images from a series or compare versions of adjusted images to see which is best.

You can use the software Loupe to magnify part of an image, perhaps to see the effect of removing blemishes or sharpening. You can position the Loupe over different portions of an image and see the magnified view.

Depending on the size of your display and Viewer, images may be displayed at a reduced size to fit in the Viewer. Aperture can display your images at full resolution, pixel for pixel, which can create images larger than can fit on your display’s screen. Displaying an image at full resolution allows you to examine the image exactly as it was recorded and see the precise effects of your adjustments and changes. In addition, you can zoom in to and out of the Viewer incrementally to check details in the image, such as sharpness.

Using two displays with your Aperture system is an excellent means of viewing your images. Aperture can show your images on both displays, allowing you to dedicate one display to enlarged views. When your system uses two or more displays, Aperture provides two Viewers, called the Main Viewer and Secondary Viewer. Just as you can with a single Viewer, you can set the Secondary Viewer to show one, three, or multiple images at a time.

You can also set metadata options that determine the amount of information that appears with each image. For example, you can display images in the Viewer with their keywords and other information, such as IPTC or EXIF metadata.
