Set image resolution when exporting

You can set the image resolution you want for exported photos in the Image Export dialog in several ways: by specifying a dpi setting, by specifying a percentage of the original, or by specifying photo dimensions in inches, centimeters, or pixels. First you select an export preset, and then you specify a resolution for that preset.

Specify the dpi setting for exported photos in an export preset

Do one of the following:
- Choose Aperture > Presets > Image Export.
- Choose File > Export > Versions (or press Shift-Command-E), then choose Edit from the Export Preset pop-up menu.
The Image Export dialog appears.
Select an export preset or create a new one, then enter a dpi setting.
For more information on creating export presets, see Work with export presets.
Specify additional settings as necessary, then click OK.

Use this export preset when you need to export versions at the resolution specified in the DPI field. Create a new preset when a new dpi setting is required.

Create an export preset constraining photos to a specific size at export

Do one of the following:
- Choose Aperture > Presets > Image Export.
- Choose File > Export > Versions (or press Shift-Command-E), then choose Edit from the Export Preset pop-up menu.
The Image Export dialog appears.
Select an export preset or create a new one.
For more information on creating export presets, see Work with export presets.
Choose an item from the Size To pop-up menu, then specify the size of the photo by entering values in the fields that appear below it.
Specify additional settings as necessary, then click OK.

Use this export preset when you need to export photos at a specific size. Create a new preset when new dimensions are required.
