Sorry, my mistake. While you may not have mentioned color film, it seems to have been taken that way by those involved in the discussion; and they just ran with it. I based my statement on a characterization of the entire explicit discussion as it evolved. Like you, the only color lantern slides from the period in question that I actually have seen were few in number and hand colored so I also did not think of color until some one proposed using color film to do the copying. When the proposal was made I questioned it given the assumption that the original slides were in black and white so there would be no point in using color and the use of color would raise archival questions to boot. >I've noticed on this list that some have problems and some don't. Maybe >it doesn't need to be silver based, just my first thought and for archival >use I would have thought safer. Like you, I have made the same noticings and come to some of the same conclusions regarding archival safety, which is why I would shy away from chromogenic B&W films even though they tend to scan batter and easier without many of the problems encountered or said to be encountered by the silver halide films. I was merely attempting to indicate that scanning silver halide films may not be as simple as your post seemed to imply ( even if that was not your actual intent or meaning). >Maybe, but I would suspect a modern camera with exposure control >should cope for much of this :-).

Here I'll admit I don't >know if these films are still available. I evidently do not have the faith that you do in the modern camera's when it comes to such things as exposure controls sans any testing by the user on the subjects at hand; but in some cases one might need to use filtration to get rid of things like stains on the slides or reflections off the slides from stray light or refraction. Here again, sometimes one has problems like this and sometimes one does not; but with the older lantern slides, unexpected problems may very well arise which would not take place with standard film based transparencies or negatives, which would only be known via testing and whose solutions would only be worked out via testing. As for your comments on contrast control, I agree; but the variety of films and developers available and easily accessible in pre-packaged form are few in number for starters; but also the current 35mm films on the market for camera as opposed to lab use tend to be on the contrasty side to begin with and often require some pre-flashing which in turn requires some testing. >I thought this was for a charity with little money.

I think that I was not so much suggesting the use of 4x5 Pro Copy as pointing out that unlike it current camera films do not have the same properties for controlling contrasts and the like as does Pro Copy which is intended for that purpose and not from general photography in normal contrasty environments. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Charles Stirling Sent: Saturday, February 09, 2002 6:44 AM To: [EMAIL PROTECTED] Subject: [filmscanners] Re: [film scanners] Re: Scanning old Lantern Slides ** Reply to note from [EMAIL PROTECTED] Thu, 7 Feb 2002 22:35:02 -0600 ...SNIP ---------------------------------------------------------------------------------------- Unsubscribe by mail to [EMAIL PROTECTED], with 'unsubscribe filmscanners' or 'unsubscribe filmscanners_digest' (as appropriate) in the message title or body
