What's the point with ISO 125?

B&W Processing and film forum from Photo.net - photo.net
Ehm... maybe I haven't understood the whole ISO metric

system (100, 200, 1600, 6400, and so on...) very well,

but... what's the deal with 125 films?!

<p>

I mean, there's an obvious difference between, say,

100 and 400 (grains, speed, and more), but what big a

difference could there be between 100 and 125? It's not

so much faster that you can clearly see a difference

in the grains or so. So... what's the point? Am I missing something?

I've tried using Kodak's 125 film, with not so positive

results compared to Tmax 100 or Fuji's Neopan SS, so...

does anyone know the "secret" behind 125 films?

<p>

Thanks.
