While the D300 images are remarkable, my workflow is completely broken. While a codec for the Nikon RAW format of the D300 has been released for Windows, Apple has not yet released their system level support for these files.
At this point, I import into Aperture as usual, but then I copy the RAW files into a folder on the hard drive where I can browse them with Capture NX. I registered my trial version with the code that came with the D300, so I have a copy of Capture NX to use.
The control point interface of Capture NX works well with my style of post processing. For example in this image, I darkened the foreground dirt area to bring out the white of the grass in the lower 1/3 of the image. I boosted the saturation of the grass at the top right to help define the upper edge of the picture plane. The control point will work on changing the tonality of all of the green leaves. In Photoshop, I’d be doing a wider dodge and burn type maneuver and altering the tone of all of the area less selectively.
