RE: [APML] To push or not to push

["Scott Hammonds" <capella@creatorsview.com>]

Matt, Robert,
Thanks for your input. Since there seems to be an argument for both
sides, I'll just test for myself and see the results. But it sounds like
pushing 1-2 stops may be my best bet for scanning the slides. 
Thanks to all who responded to my post.

push makes the slides MUCH easier to scan.  There seems to be some
genuine speed increase with the wide-field piggyback shots I do with
Nikon 35 cameras.  I have not measured the speed gain specifically
against unpushed E200, but I think my one-stop E200 is better than
non-pushed E200.

Pushing one stop is supposed to yield ISO 320. I think many scanners
have a tough time with dark slides, and pushing can help with the faint
stuff, but I suspect that it burns out the stars more. Slide film
already has a couple stops of dynamic range less than print film.
Anyway, I think pushing one stop often does more good than harm.
