Which camera notation indicates a move to a close-up of the subject?

The indication of a close-up shot in camera notation is typically represented by abbreviations that specify the movement and the framing of the shot. In this case, "DR" signifies a dolly or track movement, and "ZI" refers to zoom in. Together, they indicate that the camera is not only moving closer to the subject but also zooming in to achieve a close-up (CU) composition.

This notation conveys to the crew that the intention is to create an intimate perspective of the subject, focusing on details such as facial expressions or objects of significance. Close-ups are essential in storytelling as they enhance emotional engagement and draw viewers' attention to critical elements within the scene.

In contrast, the other choices suggest different types of movements or shots that do not specifically culminate in a close-up. Details about those expressions and movements illustrate a range of techniques, but only the choice indicating a combination of dolly and zoom specifies the transition to a close-up effectively.
