I'm not sure that I fully understand your explanation, so let me double check some things.

Are you saying that only rem jet backed films can be *fully* opaque, and that other films (developed or not) will always be slightly transparent?

Also, does higher turbidity equate to higher opacity?
Only rem jet backed films are totally opaque. Light does not pass through.

Other films are translucent or near opaque. They vary from a color such as the post by Duncan to varying degrees of being "frosted" in appearance to "passes light but no apparent image". You can see shadows through these films at the minimum.
