Which type of graphics is best represented by raster images?

Raster images are pixel-based graphics that are particularly effective for representing detailed photographs and complex images with subtle color variations. This is because raster graphics consist of a grid of individual pixels, each of which can be a different color, allowing for the intricate details and gradients found in photographs to be captured accurately.

When working with photos, the quality of a raster image is often determined by its resolution, which refers to the number of pixels in the image. Higher resolution images have more pixels, leading to greater detail and clarity, making them ideal for high-quality photographic representation. This level of detail is something that simple shapes, line art, and 3D models typically do not require or utilize in the same way, as those forms often rely more on mathematical precision or vectors than on pixel density.
