An overall 'headline' (v) score is awarded, but that is based upon an aggregated overview of a number of other very specific and detailed test attributes, although the actual weighting of those individual attributes is unknown.[1] DxOMark themselves stress that "the overall score is not a weighted sum of the sub-scores. It is a proprietary and confidential mapping of sub-scores into a combined score". DxOMark also highlight that they consult directly with the equipment manufacturers, with the objective of helping them make better cameras.[3]
