Understanding the Edge Sharpen Workflow
The Edge Sharpen adjustment in Aperture is a professional tool that’s used to sharpen
photos. Using the Edge Sharpen adjustment controls in conjunction with the following
workflow makes it easy to achieve professional results.
To sharpen an image:
1 In the Edge Sharpen area of the Adjustments Inspector or Adjustments HUD, set the
Intensity slider to the maximum value to see the effect of the operation.
2 Adjust the Edges slider so you can see which parts of the image are being sharpened.
If possible, adjust the Edges slider so that edges are sharpened, but noise and texture
in the image are not affected.
3 Adjust the Falloff slider so that the edge sizes you want sharpened the most are
accentuated.
4 Decrease the Intensity parameter value until the sharpening effect is appropriately
subtle. Values below 0.5 usually work best.
Working with Preview Images
Aperture 1.5 adds the ability to create JPEG previews of versions in the Library. These
preview images are used within Aperture and can be shared with other applications.
Previews are JPEG images generated by Aperture that represent the original master file
with any applied adjustments. You can control the size of previews, from a preview
image that has the full-size dimensions of the master file down to a preview image that
is 1280 pixels in the longest dimension. You can also control the JPEG compression
quality of the previews.
You can have Aperture create and maintain previews automatically as you add or
modify versions, or you can create previews manually whenever you need them.
Furthermore, if your workflows do not benefit from previews, you can configure
Aperture to not create them at all.
