And actually, this shot was done with the Nikon 990 at its widest setting, not with the wide angle adaptor, though I have one. It's the same model that should work with your 950, but different from the one they sell for the Collpix 5000, or 5700.
It's the Nikon WC-E63, and it has a multiplier effect of 0.63, meaning it will convert the equivalent of a 35mm view to a 22mm view (35 X 0.63).
