Bright, clear — the seeing instrument's own word, from camera lucida: the prism that lays what is seen over the paper so a hand can trace it. Not a copy made for you, but a method made traceable. Latin.
Latin lucida, feminine of lucidus (bright, clear, full of light), from lux (light). Its use here is from CAMERA LUCIDA — "light chamber" — the drawing instrument patented by William Hyde Wollaston in 1806: a prism that lets an artist see a scene and their own paper at once, so the hand can trace what the eye sees. Named in deliberate contrast to the older camera obscura.
A camera lucida for human–AI collaboration: trace the method onto your own paper. The instrument's whole virtue is the distinction it draws — it does not make the drawing for you, it makes YOUR hand able to. Nothing is copied; a way of seeing is made available.
