The art of noticing what everyone else walked right past.
means The process of discovering or uncovering something that is hidden, hard to find, or not meant to be found.
from From Latin detegere — 'de-' (undoing) plus 'tegere' (to cover, as in 'tegula,' a roof tile) — literally 'to uncover.' The same root that shelters you in 'protect' and 'tegument' gets flipped here: instead of covering something up, you're ripping the roof off.
