Final answer:
Cassie is likely working on the aspect of photography that involves controlling light exposure to manipulate shadows, brightness, and the overall mood of her images by adjusting shutter speed, aperture, and ISO sensitivity.
Step-by-step explanation:
Understanding the Impact of Light in Photography
Cassie is focusing on a critical aspect of photography: controlling light exposure to achieve the desired artistic effect. The direction of light is essential in forming shadows, giving a three-dimensional appearance, and setting the photo's mood. The mastery of lighting is what allows a photographer to create compelling images that convey a story or emotion. This is not just about how much light there is, but also about its quality and the way it interacts with the subjects and the surrounding environment.
Exploring Light and Shadow Interactions
By experimenting with the amount of light entering a camera, Cassie can produce different results in terms of shadows and brightness. This exploration is not only about achieving the correct exposure but also about how shadows can become a defining feature of the composition. For instance, shadows can be used creatively to draw attention or to become the subject themselves, potentially altering the narrative within the photo.
Technical Aspects of Exposure
Three main things affect a photo's exposure: shutter speed, aperture, and ISO sensitivity. Adjusting these settings can help prevent photos from becoming overexposed (too bright) or underexposed (too dark). Cassie will need to understand the role each of these settings plays to control the light adequately, whether she's using a digital camera with manual settings or a smartphone with pre-set scene modes.
