A comment above got me thinking about white balance. Is it always appropriate to balance the sensors rendering to the color of the light so that we always get a rendering equivalent to daylight? Look at your kids as they peer into the wonder of the christmas tree, isn't part of the charm the warm color from the multicolored lights? Did you ever sit by a cosy fireplace romancing the love of your life? Would the effect be the same if lit by the midday north light?
I'm not saying we should not be aware of white balance, but is absolute technical accuracy always the best choice?
If we are touched enough by a scene to create an image of it, does not the effect of the light in it deserve to also be rendered accurately?
Just saying.
