Nikon tells me not to use Capture NX with OS X Leopard 10.5. It seems to be working fine for me, so I’m ignoring their advice, working only on copies of the original RAWs out of Aperture.
This is truly amazing for me. Nikon has provided the new D300 picture controls in Capture NX to be applied to any RAW image. Here’s a shot from last spring’s trip to Italy processed through Capture NX set to Vivid. The image is so much more vibrant than what I see in Aperture! The color and sharpness of the D80 are really very, very good. The D300 bests it for me in functionality, metering and Active D-Lighting, but I won’t hesitate to go light and fast with the D80.
