Re: [APML] RG200 Alert

Oh Gawd, this is depressing isn't it.  The OIII was poor before, now 
they've made it even worse.  The Ha was good before, now they've flushed it 
down the pan.  Looking at these curves, I think they've re-jigged the 
formulations for pure aesthetics - good skin tones, etc.  There seems to 
have been no attempt to make the film respond accurately to the visible 
spectrum.  Notice the way they have cut the red at around 630nm - that must 
be to do with skin tones - removing blotchiness, etc.

Anyway, thanks again Joe for the good presentation, even if it is mighty 
gloomy :(
