Serious about slide duplication?

http://www.glennview.com/copy.htm Huge source, expert technical understanding.

I've duped thousands of slides using Bowens Illumitran and various chromes, mostly using Kodak dupe film or pre- flashed Kodachrome (Canon F1 body is as precise as pin registered Nikon)...I suspect the Beseler is even better...both cases with standard cassettes. I've also used a DIY system utilizing relatively heavy Durst focusing stand and daylight lightbox or strobe copy lights depending on requirements...great for small projects involving mixed format originals.

For high production versatility I've used Forox with motorized Nikon and polarized studio strobe lights (Balcar & Norman) for flat copy as well as a forgotten-brand, pin-registered long-roll 46mm camera ("super slides" used with Leltz mounts). Micro Nikkor easily covers 46mm format at macro distances.

The best by far for conventional 35mm slide dupes, assuming you need absolute maximum resolution to copy thousands (as I needed) is Sickles with Zeiss optics. Exceptionally rigid.

With the film choice of today, which way do you go?

Seem to be no wonderful film choices... Forced to dupe today I'd use slowest fresh E6 daylight film and would plan on pre flashing, perhaps 1/4 stop to reduce contrast without killing blacks...therefore using a camera that features precise frame registration (e.g. Canon F1 or pin register-modified-Nikon F series). Would take some testing to be confident in flashing and main exposure.

And I'd be very sure my E6 lab still ran a lot of pro film daily with replenished chemistry for consistency.. perhaps www.dwaynesphoto.com/newsite2006/slide-film.html or thedarkroom.com/e6-slide-film-processing If I was doing a large project I'd buy a lot of whatever E6 of the same batch in interest of consistency.
