low-res

Having a low density of pixels or dots that compose an image, resulting in a poor, unclear image quality. Short for "low resolution"; sometimes styled as "lo-res." I remember how impressed we were when our crappy little flip-screen phones started coming with built-in cameras, but the low-res pictures those things took look positively ancient compared to the brilliant pictures modern smartphones are capable of producing. The defendant's legal team successfully argued that such a low-res image could not be used to reliably identify place him at the scene of the crime without a shadow of a doubt.

lo and behold

What a surprise! Can you believe it! The very old word lo, which means “look” or “see,” today survives only in this tautological imperative, which dates from the mid-nineteenth century and is nearly always used lightly. As Edward Bulwer-Lytton wrote (Night and Morning, cited by the OED), “The fair bride was skipping down the middle . . . when lo and behold! the whiskered gentleman advanced.”
