[LargeFormat] Pre-exposure in the real world

[Bob Younger]

I think it was to allow the insertion of a ND filter; or to provide more
diffusion and less light; one is probably sufficient if your higher shutter
speeds are accurate; or you're not using the lenscap and hat approach. I've
not used pre-exposure in a long time as most of my work in the last decade
has been color transparency; so no recent experience. Others on the list I
think may provide more insight....

......and Les, I only went to the one workshop; can't claim to have "studied
under....." unfortunately.
