I’d always been rather satisfied with Aperture 3’s metadata views until I started shooting the X100. Why? Because the EXIF data in Aperture doesn’t include Fuji’s proprietary film simulation info (available in JPEG mode). And while it was frustrating on the X100, it’s become more of an issue with the X-Pro1 since I tend to play with these a lot more, especially the two Pro-Neg simulations which I’ve become quite fond of. In fact, my studio preset is based on Pro-Neg Std (with raw as a backup).
