Etymology: Overexposing is a plain formation: the prefix "over-" (meaning "excessive" or "too much") attached to "expose," which itself came into English in the late 1500s from Latin "exponere," meaning "to put out" or "set forth," built from "ex-" ("out") and "ponere" ("to place"). The sense of "exposing" to light is a much later extension. Photography was invented in the 1820s and 1830s, and the image-making sense of "expose" as "to let light fall on a sensitive plate" developed in the following decades, when photographers needed a way to describe timing the shutter. The "over-" part carries the meaning here. Photographers used "exposure" in the sense of the amount of light reaching a plate or film, and an exposure that let in too much light washed the image out to a pale, detail-less blank. Overexposing therefore describes both the action and its result: the film or sensor receives more light than it can usefully record, so highlights bleach into white and fine detail disappears.
