the dimension you can't see in a photograph but feel in a person
means The distance downward or inward from a surface — and, by extension, the quality of having complexity, intensity, or profundity rather than shallowness.
from From Middle English depthe, built from the adjective 'deep' (Old English dēop) plus the noun-forming suffix '-th' — the same suffix that turns 'wide' into 'width' and 'long' into 'length.' 'Deep' itself traces back to a Germanic root for hollow or sunken things, related to words for diving and dipping. So 'depth' is literally 'the quality of being deep,' a measurement word that drifted, over centuries, from oceans and wells into souls and minds.
