|One of Aperture's main advantages is that the original files remain unaffected. You notice this if correcting pictures. You can go back a step easily and without loss of quality. The fact that changes are saved in small files and not via a copy of the photograph frees up a lot of disk space and enables you to work very quickly. Aperture asks a lot of the processor and memory. No problem with the latest Intel Macs. The program runs extremely quickly on the new Apple MacBook Pro and you won't have to wait long, especially if you have the new Mac Pro desktop computer! It also works well on an older Powerbook, with a 1,5GHz G4 processor. I recommend working with two screens, as this increases productivity considerably. Previews on one screen, StudioDisplay or the photo on the other. If you combine this with HUD, you will have complete control over what you are doing. Transforming RAW to TIFF gives you fantastic photos. You can still make the final fine adjustments to partial areas in Photoshop. If you use iWork, you will have to skip that step. You can also make a beautiful book or lively website straight from Aperture. Everything is possible. Apple is right; with Aperture working with RAW is just as simple as working with JPEG. Highly recommended!
