In-Depth Information
To create a new preset, click the Add button (+) in the bottom left. Select a preset to change its
options, and if you change a built-in preset, you can click Reset Preset to restore it to its default state.
We cover adding watermarks to a preset in the next section, but here are the different options
available for each preset.
Image Format.
Use this pop-up menu to select the image's file type, whether it's JPEG,
PNG, TIF, or PSD. TIF and PSD also have higher-resolution 16-bit options available.
Include Metadata.
If you select this check box, Aperture embeds your image's metadata
into this exported version. Sometimes, such as when posting an image to the Web, you
might not want to have your metadata embedded into an image, especially GPS meta-
data. Note that this option is not available for PNG images.
Image Quality.
When you select JPEG for the preset's image format, use this slider to
adjust how much compression the image will have. Lower numbers mean a more com-
pressed/smaller but lower-quality file.
Size To.
Choose whether this preset exports the image at its original size, scaled to fit
within a specific dimension that you type in (specified either in pixels, inches, or centi-
meters), or scaled to a percentage of the original image size.
DPI.
Specify the dots per inch resolution at which to export your images.
Gamma Adjust.
This option lets you apply a gamma curve to your image to adjust the
midrange brightness. In general, we recommend using a color-calibrated workflow and
making adjustments to your image rather than relying on this setting. However, if you're
creating an export preset for a specific purpose and find that the midrange brightness of
your images is consistently off for that purpose, the Gamma Adjust slider lets you add a
correction to the preset.
Color Profile.
This pop-up menu allows you to select the color profile that Aperture
embeds into this version. We typically recommend ProPhoto or Adobe RGB (1998) for
most display or print purposes, and sRGB for Web or e-mail.
Black Point Compensation.
Selecting this check box causes Aperture to scale the black
and white values in your image to fit within the export color space. This prevents
shadow areas from becoming solid black and highlight areas from becoming solid white,
but it might also cause subtle tonal changes throughout your image.
