<p>[QUOTE=&quot;davidh, post: 2883304, member: 15062&quot;]Digital pictures are made up of pixels, each of which is a colored point.&nbsp; If you quadruple the image size (double both the height and width) you&#039;re also quadrupling the pixel size.&nbsp; This means that a 2048x2048 pixel size picture for which the height and width are doubled will have an effective pixel size of 512x512.&nbsp; If the size is tripled in height and width, the effective pixel size is 256x256.&nbsp; Every time you enlarge the picture you enlarge the pixels and you lose resolution, so enlarging to see more detail doesn&#039;t work; you still have the same detail, it&#039;s just blockier.[/QUOTE]</p><p><br /></p>
