Regarding the processing. So far I have been using the JPEGs, not the RAW files. I hate having to go through another step when processing, as Aperture does not support the RAW files yet.
I set the camera to standard film simulation (Provia) and DR to 100, sometimes DR200 if especially contrasty scene. I set Highlights to -1 and Shadows to +1 to have a little bit to play with in PP. NR to -1 and sharpening to -1. JPEG fine of course.
In Aperture I first convert to B+W. The standard settings are Red +30, Green+59 and Blue +11. I tend to bring down green a bit and increase red for landscapes, but leave more or less alone for most other types of images. You can of course simulate colour filters by bringing one or more channels way up or down. I then adjust contrast by using the histogram view, rather than curves, by re-setting white and black points, and adjusting gamma, and 1/4 and 3/4 gamma until I get a tonal spectrum I am happy with.
I sharpen to 0.75 or 1.00 radius and 1.00 intensity. But may on occasion sharpen just parts of the picture selectively. I also dodge and burn on occassion when I want to protect other areas from blowing or blocking. As with the bath house above, the house came out a shade too grey, whilst the rest of the whites were white enough. So I dodged the house rather than bring up the highlights in general.
And since I often shoot with B+W in mind I use grad colour filters to increase contrast between sky and clouds, no matter that it ruins any chance of a good colour capture.
