Cool colors. I need to try this.

With the Sigma SD1 Merrill, there is no live view and the Foveon red layer response is about 1 EV less than the green and blue layers.
So it is that RawDigger can be very helpful when checking a full-spectrum capture:
The blue bits at left in the review image are Low-Value warnings. In the log-log raw histogram, Ev0 is set to the clipping point of the Foveon levels - about 4080 in the SD1, so no raw clipping in this shot. There are no adjustments made to RawDigger review images: in the above, the Values are straight from the sensor with no color space used.
When opened in Sigma's proprietary converter SPP 5.5.3, we now see some color:
We see some Kodak-esque reds and nice blue sky a la full-spectrum.
Some adjustments in SPP gets us a bit more colorful:
The color adjustment circle uses Cyan/Magenta/Yellow (unlike the more usual RGB) thereby forcing the hapless User to think in opposites, for example: to get more red, move the dot thingy in the opposite direction of Cyan.
And then off to RawTherapee for more adjustment, mainly acutance:
Finally:
Comments invited.
Raw available here for those who would like to play ...

One good thing about the Sigma+Foveon DSLR's is that the UV/IR blocking filter is located in the lens mount and can be removed and replaced by the User, i.e. no camera modification is necessary and there is no CFA that gets left in place like on non-Foveon cameras and no real need for channel-swapping either..

I personally like this Kodak-esque rendering most :)
Sky is nicely contrasting with trees and at the same time their colors match in some twisted way.
On other images sky is a bit too pink and clouds are not so voluminous, also trees look overly bright. -
Agreed - I do have tendency to go over the top!

Wellington, New Zealand. Blue/IR filter on a full spectrum camera, 10 shot panorama stitch processed in Lightroom.

Gorgeous colors. The blue/IR works really well. Combining 10 images is a lot of work, but it was definitely what this picture requires. Well done.

Colors are less intense than other images, matching the subject well. Looks angelic and pure.
