Re: [APML] Orion's Sword on 400F

Matt,

I think you're correct, the 400F does lack red 
sensitivity at least to my eye. Too bad, I was hoping 
this film was better. Also, I didin't realize it was a 
transparency film. So thanks for posting this. I'll 
stick with E200 for now.

Too bad. The search continues.
