What does the resolution of an image determine?

The resolution of an image primarily determines the amount of detail represented in that image. Resolution refers to the number of pixels in an image, typically expressed as width by height (for example, 1920 x 1080). Higher resolution images contain more pixels, which means they can display finer details and provide clearer, sharper visuals. As a result, images with higher resolutions will show more intricate patterns, gradients, and textures, leading to greater overall clarity compared to lower resolution images.

In contrast to how resolution impacts detail, color depth pertains to the number of bits used to represent the color of each pixel, which affects how many distinct colors can be displayed but does not directly relate to the image’s detail. The file size depends on various factors including resolution, color depth, and compression but is not solely determined by resolution. The image format plays a role in how images are stored and can impact file size and quality, but it does not influence the detail captured in the image itself.
