I have some dubts about the function of a few kinds of filters and if you could explain to me it would be great!
I've tried to check online but i haven't found a clear explanation, maybe it's because my english is terrible!
So, how a Tiffen hot mirror works an which is the difference from a PV TIFFEN HOT MIRROR IRND (infrared and ND too?)
Why in digital cinematography is so important use IR filters and in which cases they works better?
And finally what PV means? I think something about the noise reduction for digital cinematography but I'm not sure! =)
Sorry for that kind of asks! I'm a noob!
Thank you very much!
