I'm guessing it's a fairly simple question, so please bear with me as I'm working my way round trying to understand the DNG format:
After the de-bayering step, are DNG camera profiles pure 3-channel mathematical curves? I know Adobe DNG editor allows for adjustments from the Color-checker patches & there's some hue sliders etc, but do these build into RGB curves, or is it some kind of additional mild LUT (or something else) applied over the top?
read here how DNG (dcp) profiles are guiding (or rather how info there is being used by a code) the color transform in Adobe converters = http://wwwimages.adobe.com/content/dam/Adobe/en/products/photoshop/pdfs/dng_spec_18.104.22.168.p dfутили
also Sandy Mc... utility is useful to peek inside dpc profiles data = dcptool.sourceforge.net
may be also the following link = Dcp or Icc Profile?
