Tech techniques

After wading through two sections of Sunday Calendar filled with nothing but Summer Sneaks hoopla, it was wonderful to find the article on Chauvet cave [“A New Perspective on Art and Early Man,” May 9]. The photos of the cave art were stunning.

However, the article states that the art is documented by “taking high-resolution digital photographs of the works, which will be scanned into computers at the lab.” One does not scan digital photos into a computer, they are simply transferred electronically from camera to computer. Photos are scanned into a computer only when they exist as photographic prints; indeed, a major advantage of digital photos is the ease of camera-to-computer transfer, without having to make a print, then scan it.
