Some pixel dimensions are slightly different after upgrade to Aperture 3
Symptoms
The pixel dimensions for some RAW images in your library may be slightly different after you upgrade to Aperture 3.
Products Affected
Aperture 3.x
Resolution
Aperture 3 more accurately calculates the pixel size of RAW images for certain cameras. As a result, you may notice very small differences in image size after upgrading to Aperture 3, if you reprocess existing masters. If you have cropped the affected images, the crop may also be slightly affected. The difference is typically less than 8 pixels in one or both directions. With Aperture 3, RAW and JPEG masters will be identical in size in the cases where they were shot full-sized and uncropped.
