Fool's errand: the SD14 uses a WB correction matrix, no WBGain. CamToXYZ_Flash matrix follows so the chances of being able to transpose between the 2 cameras, well... it's beyond me

Sad to hear.

A point or three:

The transform from XYZ to sRGB is well known, if that helps. In other words, you could easily derive a cam-to-RGB matrix.

By the way, the WB correction follows the camtoXYZ, not the other way around, AFAIK. In other words, I think you must have XYZ values before applying an XYZ correction matrix.

The SD15 is no different to the SD14 when shot at 100 ISO - as far as the AFE is concerned.

Shame because I'd love to be able to have my SD1M render a la the SD14 for natural light photography too, ach well.

So you like a green cast, eh? Just kidding ...
