What does 'resolution' indicate in relation to image quality?

Resolution refers to the level of detail an image contains, which directly affects the clarity and sharpness of the image. High resolution means that an image has more pixels, allowing for finer details to be displayed. This is particularly important in graphic communication, as higher resolution images provide a better visual experience and allow for larger print sizes without losing quality. When discussing image quality, resolution is a key factor because it defines how much information the image can portray; the more pixels, the more detail and clarity are achievable.

In contrast, color accuracy relates to how closely the colors in an image match their intended appearances, which is a separate aspect of quality. Lighting conditions affect the brightness and visibility of the image, rather than its detail, and while file size can influence an image's resolution, it does not directly define what resolution means in terms of image quality.
