If you want to have the best program to import, manage and improve your images and digital photos, Aperture is what you are looking for. This program developed by Apple is the reference in the field of image management and small modifications on Mac OS.
The official Apple image cataloger
With a well-kept interface, like all the ones that Apple has us used to, Aperture allows us to catalog any photo with tags and albums. Furthermore, it automatically detects people's faces and catalogs them, thus it will be very easy to find photographs of the same person. What's more, it allows you to geotag any photo thanks to its EXIF data and later see the exact location on a map. Something very interesting for photos taken during trips.
Aperture also offers you general editing tools, with several brushes, possibility to perform color or brightness adjustments. Furthermore, this software imports photos from any camera and allows you to choose the ones that are going to be saved and the ones that we want to eliminate easily.
Logically, Aperture also includes the possibility to create photo presentations, as well as exporting them directly to an iPhone or iPod via iTunes.
