According to Wagner at Silicon Imaging, the truest curve is the linear curve with the black and white points pulled slightly towards the centre. All the others are to add a bit of punch and make a picture more like the way we've come to expect it to look on film ( - at least that's my simplified understanding of what he said!)


It's a shame Sinar don't include a "true" curve in their Standard Curve set. Since the colour calibration process involves shooting a known target (Macbeth 240 patch) you'd think it'd be possible to produce a file/curve where the readable values of the patches on screen correspond to their actual values on the chart.

How they came to produce the 3 "standard" curves and for what purposes is, I confess, a mystery.
