Note: This hint will only apply to photos taken on an iPhone running iOS 4.1 or higher, and requires you to be using iPhoto '09 or newer.
This is a revisit of my previous hint for making a smart album in iPhoto to keep track of only your new iPhone 4 photos. With the release of iOS 4.1, apple has changed the camera model to 'Apple iPhone 4' making it much easier to filter these photos into smart albums. In addition to that, we can use the camera aperture metadata to filter between front and back camera photos.
The front (FaceTime) camera:
- iPhone 4 Front Camera Smart Album:
- Match - all - of the following conditions:
- Camera Model - is - Apple iPhone 4
- Aperture - is less than 2.6
- iPhone 4 Back Camera Smart Album:
- Match - all - of the following conditions:
- Camera Model - is - Apple iPhone 4
- Aperture - is greater than 2.6
