The Web Export Presets dialog includes these controls: Â Image Format pop-up menu: Choose an image format to convert your images to, such as JPEG or PNG, from this pop-up menu. Â Include Metadata checkbox: Select this checkbox to include EXIF and IPTC metadata information in the image files. Â 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. Â Gamma Adjust slider: Gamma describes how your image distributes brightness. Drag the slider to apply a uniform gamma adjustment to your exported images. Â 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. Â 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. For more information about adding watermarks, see "Adding Watermarks to Webpage Images" on page 559. 556 Part IV Distribution and Backup
