EBarnacle - That's not an effect of digital - that's an effect of the ISO, or "film" speed, that you are using in combination with your shutter speed. Slow films, such as an ISO 100 or 200, could not get enough light without having an extremely long shutter speed. If you've got a point and shoot type camera, it probably has a set shutter speed of about 1/125 of a second. A camera or film with an ISO of 1600 or even 3200 would be able to get enough light with a relatively short shutter speed. Or he may have been using long shutter speeds - in excess of one second. Was he using a tripod, by chance?
