Yeah, that turns it into colloidal silver. You can tell by the reddish tint the film takes. I've also found that in strong enough sunlight, Florida for example, you can do it with just straight water.

to eliminate the haze or scatter put it in a weak vitamin c bath and expose to a strong light, i got this on my full color holos and this helped alot and will help contrast so the blue will be stronger

I'm not sure that would work Tom. The scattered light is mostly blue, it would go right through your "filter".
