Mr. Moose (couldn't resist), I am having some trouble digitizing with Digi-View. I am able to get some photos with decent result s, unless there is a fair amount of dark content. Although this seems to me a reasonable limit to the system. I am however using a great amount of line-art for newsletters and cagalogs. This is where things fall apart. A straight line .03mm dark and crisp will show to be between 4-6 pixels wide, and in soft grey tones using Dpaint (or anything else). To retrace a simple drawing tak ees me about 6-6 1/2 hours of clean-up. (No joy here). I have an Amiga 1000,Panasonic WV-1410, C-mounted Vivatar 28mm lens, 2 Co ol white circular lamps @ 22W each. And a decent copy stand. I can move the lights wherever I choose, but that doesn't seem to make much of a difference. I also have a Polarizing filter, and that seems to buy little help as well. I have tried stopping the lens down, to see if I was throwing too much light on the target, with only poorer results. I have also tried setting the levels on the control screen, to very little improvement. I have checked out my cable, camera, software at my local computer shop, and have replaced the cable. (I couldn't get a sharp image at all with the old cable). Switching lenses does not give improved image with line-art subjects. I have also tried to take the image in the Line-Art mode, and you cannot tell what the subject was to begin with. In the B&W mode, I have a lack of crispness. Any help would be very much welcome!! Thank-You in advance, Bob Felts, 72767,642 P.S. I have uploaded a Digi-Pic to the AmigaArts forum that does your product some justice, you may wish to check it out, Viking lzh on New Uploads. Hope to hear from you soon, Bob

Hi Bob, I also am having some of the same problems you have experienced and am interested in some tips on improving my Pics. I do have a question for you though…. You said you have a C-Mounted Vivitar lens mounted to your camera. I have a Canon 35mm Camera with an assortment of len's. I have heard that using 35mm camera len's with the Panasonic camera improves the quality of the digitized pics. I have not been able to find a C-Mount adapter for the Canon lens. Do you know where I could get one? The local camera stores in my area have not been to helpful. Ray

Ray – Try looking through the phone book for Video Equipment – Dealers. Find a Panasonic dealer who advertises he serves the commercial or educational market. Chances are that he'll have the adapter. They were running about $50 (as I recall) last time I looked into it in this area. Bill, K3OZM

Bob, I had to digitize some line art for the first time a few weeks ago. I was thinking: "Boy, this will be impossible with a video camera and Digi-View". I was wrong. Needless to say, you need lots of light on your image. After that, you can try digitizing line-art, although a good portion of the image may look like mud using the default settings. For a clean line-art rendering, try elevating the BRIGHTNESS and CONTRAST settings… Real high, like in the teens or higher. I forget, but you'll want one higher than the other (I think it's BRIGHTNESS). Good luck!
