What panel do you use to make adjustments to an effect once you have applied it?

The Effect Controls panel is the primary interface for modifying effects that have been applied to a layer in Adobe After Effects. Once an effect is added to a layer, this panel allows users to see all the properties of the effect, enabling them to fine-tune parameters such as intensity, blur amount, color adjustments, and any other customizable features that the effect includes.

This panel is pivotal because it not only displays the applied effects but also provides sliders, numerical fields, and various controls that facilitate dynamic adjustments in real-time, allowing for precise control over the visual characteristics of the effect. By manipulating these properties, users can create and refine complex compositions with intricate detail.

In contrast, other panels like the Layer Properties provide general layer settings, the Timeline Panel focuses on timing and sequencing of layers and animations, and the Composition Settings manage the project settings such as resolution and frame rate. None of these panels are designed specifically for adjusting effects like the Effect Controls panel is.
