I'm having fun with this process. Now to figure out how to "shoot" for maximum effect when I do go out next. Less sky seems to be the important part of the equation as one doesn't get as much of the effect in sky as one does in the mid-tone ranges. Plus the blue skies are still too blue for the autochrome look to be successful...in real life autochromes the skies tended to white out more than I can do in CS5. Ah, the foolery one must do to make an authentic image.
I like this image still even if it does have too much sky detail in it.
