Mark Galer, Philip Andrews · 2004
The images to the right have the same pixel dimensions (300 × 300) but different resolutions. The large image has a resolution half that of the small one. A digital image can be made to appear bigger or smaller without changing the total number of pixels, e.g. a small print or a big poster. This is because a pixel has no fi xed size. The pixel size, and therefore the resulting document size, is determined by the resolution assigned to the image by the capture device or image editing software. Increasing the resolution of a digital image decreases the size of the pixels and therefore the output size of the fi le.
