The Web Export Presets dialog includes these controls:
 Image Format pop-up menu: Choose an image format to convert your images to,
such as JPEG or PNG, from this pop-up menu.
 Include Metadata checkbox: Select this checkbox to include EXIF and IPTC metadata
information in the image files.
 Image Quality slider: Choose how much to compress your JPEG files by dragging the
slider to a number. Setting the slider to 12 applies the least compression and results
in a higher-quality image; setting the slider to 0 (zero) applies the most compression
and results in a lower-quality image.
 Gamma Adjust slider: Gamma describes how your image distributes brightness. Drag
the slider to apply a uniform gamma adjustment to your exported images.
 ColorSync Profile pop-up menu: Choosing a ColorSync profile ensures consistent color
reproduction on other systems and in the printed image. Aperture provides a large
selection of profiles, as well as any custom profiles you’ve saved during calibration. To
apply a ColorSync profile to the images you’ve selected for export, choose a profile
from the pop-up menu.
 Show Watermark checkbox: A watermark is a visible graphic or text overlay that is
applied to an image. Photographers often use watermarks to indicate that images
are protected by a copyright and discourage others from inappropriately using their
images. To add a watermark to your images, select the Show Watermark checkbox.
After selecting the checkbox, you can select a file to apply as a watermark image. You
can place your watermark in various positions on your image.
