Mail to me and I'll post a summary. We have done this without any extra equipment. We used a Kodak Ektagraphic slide projector, WITHOUT the lense installed. Our camera has a macro position on its lense -- we used that. OOOOOPPPPPSSSS! (occupational hazard - the following item COULD be considered EXTRA EQUIPMENT! Since we use it all the time, we become blase. :-) Sorry 'bout that.) We used a dissolve control unit to adjust the brightness of the projector lamp to achieve good contrast and to make the camera operate in the middle of its sensitivity range. Set up the camera with the macro setting on the lense and point it down the EMPTY lense barrel of the projector towards the slide. Adjust the projector lamp to partial brightness using the dissolve controller. Film. Grab. Change slide. Repeat. We got real good contrast and control with this setup, and the slides were very clear on S-VHS tapes. Luck. ______________________________________________________________ | Rick McCormack | IMAGISTICS BUSINESS THEATRE TECHNOLOGY | | Vancouver, BC | Information transfer - with a purpose. | | CANADA | ________________________________________ | | AOL: Rique | INTERACTIVE COMPREHENSIVE ENLIGHTENING | |________________|____________________________________________|

Greetings, In putting together a videodisc project, I have the need to scan large numbers of 35mm slides onto s-vhs tape. I have a scanner to do this, but I am wondering if it's possible to use my s-vhs camera and some sort of simple slide projector/adaptor. [Using the camera would offer more flexibility]. If anyone can supply information (manufacturers, capabilites, 1sthand experience, cost, etc), I'd be much obliged. Mail to me and I'll post a summary. Thanks! --Greg gf0c@andrew.cmu.edu

This sounds like a very good solution, especially since it avoids any mirrors or screens, or any other source of distortion. But one little thing I would point out is that if you do this, for the slide to appear correctly it must be inserted in the carousel *backwards*, ie; so that the side that says "this side toward screen" is actually toward the projector lamp. Otherwise the slides will appear mirrored about the vertical axis (left-to-right). Also I suppose at the same time you would rotate the slides so they appear right- side-up (normally of course the slides are inserted in the carousel tray with the image upside-down). Otherwise you would have to turn the camera upside- down as well. Dave
