DIGITAL PHOTO NOV ''22 In a recent edition of the sunday time there was large colour photo somewhere between A3-A4. The square blocks caused by JPEG compression made the photo look like it had beeen made from coloured. Whatever camera it was shot on ( and the suspicion is that it was Camon 5D) What the resolution effered by a camera actually is has been a matter for debate for some time, but things are about to become clearer.
