SD14 full spectrum to mono and mention of a cat . .
2

. . . as in "there are many ways to skin a cat".

Inspired by Gary Radford's recent full-spectrum shots and WB advice, I pulled the dustcover out of the SD14 and went testing. The results were less than encouraging at first:

converted in RawTherapee

As implied by the histogram - a seriously flat and boring image.

Then I thought of mono, not that I'm a great fan. Since SPP won't split the layers for the SD14 (like it does for the SD1M), I went to RawDigger and exported the best-exposed layer which was . . . (hmm, guess what):

Raw Red Layer extracted by RawDigger - as is.

The black border is masked sensor pixels.

Still looked a bit flat, so off I went to FastStone Viewer in order to tart it up a bit with Levels:

I allowed the chicken's highlights to blow so as to get more mid-range contrast - Curves might have been "better".

The histogram looks lower because of the black masked levels spiking at left - oops, should have told RD to just show the "effective pixels"! Still, the improved contrast comes from how much wider the curve is compared to the first histogram.

Not sure what the point of this post is except perhaps that relying on SPP to do everything is limiting and that alternative methods can be rewarding.

Here's a sky shot opened four different ways:
