A bit of an excuse. Also a bit of safety. I'll be using 1.5 mm chisels on buffalo horn in a work field 3 cm x 1 cm x .5 cm deep. A loupe has a focal lenght of under a couple of inches. Do I really want my eye ball within a couple of inches of the tool and the work? A really good large magnifying glass is about the same price as a medium grade digital camera. I know that my Nikon film SLR and macro lense works. I would think that there is no inherent reason why any digital camera with an LCD real-time viewer couldn't be capable of this. Whether they actually put that capability into the camera is a different story best answered at the camera shop. The only question then will be if there is a driver in the linux kernel that will work for the camera. The Nikon Digital SLR is, I think, an 18 MP camera with good depth of field; don't know if it can hook up with a USB as a webcam. The Panasonic 8 MP cameras with a macro funcition built-in have an adequate depth-of-field; ditto. Doug. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
