Late-Breaking News About Aperture 1.5.2
Aperture 1.5.2 provides performance, reliability, and compatibility enhancements.
Note: Aperture 1.5.2 is designed to run natively on both PowerPC-based and Intel-
based Macintosh computers.
Suppressing Preview Generation When Opening Aperture
When Aperture is opened, it begins updating previews for those projects whose Maintain
Previews setting is enabled. (For more information about maintaining previews, see
“
Controlling Previews with the Project Action Pop-Up Menu ” on page 13.) This can cause
problems if a project contains damaged files or images in unsupported file formats. In
Aperture 1.5.2, you can suppress preview generation when opening Aperture, allowing
you to more easily identify the damaged image files. To do this, press the Shift key while
opening Aperture. You can also cancel the current preview maintenance operation using
the Background Task List window. For more information, see “
Viewing Preview
Generation Progress in the Background Task List Window ” on page 17.
Note: If you have canceled a preview maintenance operation, the previews are not
updated until another change is made to the image. To force Aperture to update the
preview for an image, see “
Controlling Previews with Shortcut Menus ” on page 14. The
next time you open Aperture, automatic preview maintenance resumes.
Scaling Watermarks
Aperture 1.5.2 provides the ability to turn watermark scaling on and off. Aperture
allows you to scale a watermark by the same amount as the exported image. For
example, if the image is exported at 50 percent of its original size, the watermark is
also scaled to 50 percent of its original size to maintain the watermark’s visual
appearance in relation to the image as a whole. However, you can keep watermark
scaling turned off when it’s important to maintain the size of your watermark
regardless of the size of the exported image.
To export images with scaled watermarks:
1 Select the images you want to export.
2 Choose File > Export > Export Versions (or press Command-Shift-E).
3 In the dialog that appears, choose Edit from the Export Preset pop-up menu.
4 In the Export Presets dialog, select the export preset you want to use to export your images.
