"Opacity" Natural Recordings by Native Speakers
The word "opacity" refers to the quality or state of being opaque, meaning that a substance, material, or medium is unable to transmit light or other forms of electromagnetic radiation and instead blocks or absorbs them. In other words, something that is opaque is not transparent or clear, but rather opaque or solid. In addition, the term is sometimes used metaphorically to describe the clarity or lack thereof in communication, writing, or other forms of expression, implying that the information or ideas being conveyed are unclear or difficult to understand.

Op-eds are often used to provide a platform for experts, politicians, or thought leaders to share their views on current events, politics, or social issues.
Opacified refers to something that has become cloudy or opaque, often due to the presence of a substance or particles. This term is commonly used in medical and scientific contexts to describe changes in the clarity or transparency of body fluids, tissues, or materials.

Opacify means to make (a liquid or gas) thick and cloudy by adding a substance that absorbs or scatters light, or to make something opaque by adding a material or substance that blocks or reduces light transmission. For example, "The painter opacified the paint with a white pigment to create a matte finish."

An opalotype is a type of early photographic printing process that uses a glass plate coated with a layer of collodion to produce a negative image. The plate is exposed in a camera, then developing solutions are applied to produce a positive print. Opalotypes, also known as wet plate collodion process, were widely used in the mid-19th century. They are characterized by their soft, dreamy quality and warm, brownish tones.
