Re: Multi-Spectral Imagery to Detect Deterioration

[East75th <east75th@xxxxxxxxxxxxxxxx>]

Bill:
I hope you noticed the other theme of the story: that a truly objective 
method would result in images that are deemed to be flat and unappealing 
and thus unlikely to attract widespread commercial application.  His 
methods are likely to remain an academic pursuit.  The implication of the 
article is that current color reproductive processes are largely normative, 
perhaps unconsciously so, in that technicians produce images as they think 
they should appear, generally with boosted contrast and saturation, rather 
than how they actually appear.  To many of us, this is more confirmation 
than revelation.

It seems to me that digital cameras could omit these subjective biases, but 
I wonder if the designers deliberately program them into the software to 
make the results more acceptable if less accurate?
