Setting Up the Viewer for Onscreen Proong
Photos displayed on your computer screen may look dierent when displayed on computer
screens that use dierent color technologies. Your photos may also reproduce dierently in print
depending on the type of printer, the paper used, and the color prole of the printing device.
To see what a photo will look like when you print it or view it on a dierent display, you can
have Aperture adjust your display so that your photos resemble the nal results. To adjust
your computer display, you choose a proong prole that matches, as closely as possible, the
characteristics of the nal output device. For example, if your photo will be printed on sheet-
fed coated paper, you can choose a proong prole for sheet-fed coated paper to see a close
approximation of what the printed photo might look like. Aperture provides several dozen
proles that match the characteristics of many printers, display devices, and color spaces.
After choosing a proong prole that matches the nal output of the photo, you turn on the
onscreen proong feature, and the photo changes to show the expected results.
Onscreen proong alters the look of photos in the Viewer and in Full Screen view.
To choose a proong prole
m Choose View > Proong Prole, then choose the prole you want from the submenu.
To turn onscreen proong on or o
m Choose View > Onscreen Proong (or press Shift-Option-P).
