Apple is showing an updated version of its professional photography workflow application, Aperture at the Photography Marketing Association (PMA) show in Orlando, Florida. In addition to being Intel-native, Aperture 1.1 also boasts significant speed increases on both the PowerBook G4 and the Intel processors.

Kirk Paulsen, Apple's senior director, market development professional applications, told Macworld on Sunday that Aperture is being shown on the new MacBook Pro and iMac. While Aperture includes a significant number of improvements, the performance of the application on existing PowerPC- and Intel-based machines is impressive.

According to Paulsen, using a Lift and Stamp operation in Aperture 1.1 on a PowerBook G4 shows a 2x increase in speed from the older Aperture 1.0 on the same machine. Using the same operation on the Intel-based MacBook Pro nets another 2-3x speed boost.
