even if you don't subscribe to the social criticisms, Lena simply isn't representative of imagery nowadays. The colour balance is wrong, its from film and the dynamic range is limited.

You're better off montecarlo sampling 20 images from instagram using different geolocations.

Please please no, we'd end up having max hdr and saturation as a reference. If anything, we need to dial down these, not up.

I'm not really talking about HDR, as that a bit well, subjective.

I'm talking about using an image that that was captured by a device that can have 12-18stops of dynamic range. Something better than film, something better than 70's film rendered in magazine print and scanned in later.

or more succinctly, something that would capture the whole range of a colourspace.

I completely agree on dynamic range, and on the fact that we should use a reference image (or images) more inline with modern camera equipment. I don't believe though that _random_ instagram content would provide a good, balanced reference :-)
