The amount of detail in an image. Digital images are measured by the number of pixels per inch (ppi). For printing, resolution is measured by the number of dots printed in a linear inch (dpi). The higher the resolution, the larger the file size.

The resolution of the left image is 60 pixels per inch (ppi). The resolution of the right image is 240 pixels per inch (ppi). To create more-detailed images, increase the resolution setting in your camera.
