I picked this information in the news a few days ago: A scientific team (french, I think) have found an additive (silver by-product) which, when added to the ph otographic emulsions (at1/10.000), makes them 10X more sensitive without affecti ng the grain! They said the technology will be applied to X-Rays films at first and then to photographic emulsions by the next three years. Mmh... freezing move ments (water falls, wind, people etc.) at 1/500 f22 on fine grain sheet films, s ounds nice! Has someone heard of too? (No, it's not a late fools'day hoax!)

In all seriousness I think I have heard about this somewhere as well, but is it not some thing to do with ants saliva or something connected with them?

It is an ant saliva product but is only in preliminary development. I think I recall there were questions about emulsion stability and being able to produce a synthetic version which could be manufactured in quantity.

The company developing the additive is Agfa, I think. An article in the Chicago Tribume reported on this. Imagine 8x10 landscapes at 1/250 at f64. Wind, What wind? If only we all love long enough!

Um, if that URL didn't work for others (it didn't for me), go to www.photo.net/photo > Original Q&A > Older messages > Film > "What is the story on 10x speed film?" (You'll have to scroll down a ways; it was posted on 12/23/99 and they're in reverse chrono order.)
