Hi John, Hope you're still around. I'm still trying to decide what to do about output. I wish I could see an example of "industrial quality" video using a commerial VCR and a Targa 64 or comparable. If you have a VHS you could send me I will pay the C.O.D. charges. My address is: 700 S. Lewis Ln. #1700 Carbondale, IL 62901 Please call me collect if you have any questions at 618-549-3387. I read in one of your msgs. to someone that you use the internet to do file transfers and stuff. I just got an account with the University here, I'm an ulumnus. Is it really possible to connect to this forum using my local internet node number? I may have misunderstood you. Do you have any experience shooting 35mm slides off your screen? I use to do that alot when I only had ACAD r10 and a 287 with a 14" EGA monitor. Now I'm doing a little better in the way of hardware and software including an SVGA 20" monitor. I have a photographer friend with a 17" SVGA who will do it for me (one of the reasons I wanted a GIF viewer) if I can just give him the files. It would be alot easier for him than trying to come to my place. He's also a CompuServe user. Does sceen size make a difference? I was all ready to buy a CD ROM so I could get "Texture Universe" until I was told that it only works with 3DS r3. Always a catch eh? I hope I'm not being a nuicence. So far, you're the only real connection or "friend" I've made on this network. I'm not a real hacker and I'm always going out of town for one reason or another. Thanks again. -Tim

Of course you're not being a nuisance. This is a public forum, and if I didn't want to be here, I wouldn't log on <g>. I can't send you a tape, but you can contact your nearest Autodesk Multimedia dealer, and ask for a 3D Studio demo reel. This will have a lot of stuff on it, and will give you an excellent point of reference for 3DS content and ouput. I don't think you can access any Compuserve stuff without a Compuserve account. This is, after all, a corporate run (H+R Block), for profit information service. I haven't shot anything off screen. I usually take image files to a service bureau for still images. This will definitely get you better image quality than a screen shot. And if you want a 3DS screen capture, there's an undocumented feature that allow you to do this, but I can't remember the exacte 3ds.set parameter. I think it's in this month's 3D Artist. If you're set on photographing the monitor, then be prepared for second rate image quality, although I would do this if I was going for the "raw video" look, like in an industrial/artsy sort of peice. Naturally, the bigger the monitor, finer the display (smaller dot pitch), and higher refresh rate, the better the photo will come out. John Tissavary (LUNA cie)

Timothy Bulson Just thought I'd come in on this one for you. In my college lab, photographing the screen is often the only economical way to get an image for the student budget. While it does not give the best quality, this kind of image does work well enough to get the point across and works well as a "portfolio" review catalog. Some things to keep in mind. 1. Set the shutter at under 1/10th second (this assures no refresh band shows) 2. Use the lowest speed film you can find (slide film, professional quality Ektachrome, Fugichome, or the like) 3. Make a shield to block side light or turn all the lights off in the room 4. Expose for the highlights a. meter a white screen (this give best exposure for white, prserves highlight detail) b. give two stops more exposure (if you expose based upon the white screen settings, all white things will appear gray or dull, this is because all light meters give an average of the light enetering the metered area and indicate the best average exposure). for example: if the meter says f16 @ 1/4th second, use f8 @ 1/4th c. You may want to set up a test screen with a portrait, color bars, gray scale, etc… and bracket the exposures by 1/2 stops 3 stops +/- best guess. d. Use a longer focal length lens, 50mm – 80mm (this gives less edge distortion). e. Use an 85b filter over the lens. (a computer monitor gives a bluish light from the phosphor coating inside the picture tube which our eyes correct for, but the film will show) the 85b orange filter is the complementary color to the blue shift and absorbs that blue color Good luck Greg

PMJI, but I've done some 35mm screen shots but I can't say that I'd recommend it for serious reproductions. Here are some guide lines if you want to try: First, you want to be shooting the FLATTEST monitor you can find. Next, you want it at the fastest non-interlaced sync possible (say, 70 hz). Next, you want a video card that can do true color (24-bit) at the highest resolution possible (ideally 1024×768). The size of the monitor really doesn't matter that much. Ok, so much for computer hardware. The larger the lens the better – an ideal canidate would be a 200mm macro (negating any screen curvature). A good tripod, ideally with levels (a small level attatched to the flash shoe can work too). Try F5.6 @ 2 seconds and bracket each way for starters (your light meter will not be of much help I'm afraid). You may easily get a blue cast to the images and may want to try experimenting with an amber or orange filter or other films. Of course the easiest way is to send the images to someone with a film recorder – perfect every time. – Phil p.s. don't forget to make your images correspond to a 3:2 ratio if you want them to be full frame.

Tim – Yes, you can get access to this forum via Inet. You still must have a CIS account, but you avoid the standard connect-time charges; surcharges still apply. I have included below some lucid instructions sent to me by Mike King, 73710,1430, a sysop of the new Internet+ forum. They worked perfectly, first try, dialing University servers from off-campus (I am also in Illinois); I, however, am not a hacker, and found running a session in terminal mode, (after using WinCim for Forum sessions) a bit daunting. I asked him for very short, VERY simple instructions. <<It would be difficult to give you a short answer and make it simple. However, what you need to do is get to your account that offers Internet access, then enter telnet Ensure the settings for telnet are as follows: Enable binary Disable escape Enable CRLF options Set terminal type to VT100 Set line mode However, since there are differences between telnet programs, I'm going to refer you to your system adminstration to determine how to do so. After you've done this, enter open compuserve.com The "host" you want is "CIS." Then choose a baud rate; that'll determine your billing for the session. Next, log on, entering your user id and password. When you get a prompt of some sort, enter GO ASOFT. From that point, everything is pretty well documented within CompuServe. Type "help" for help with most topics inside the forum. If you've also got dialup capability, I think you'll find that option to be the best for accessing CIS. Mike>> Hope this helps.
