I recently shot a commercial of the week in McAllen and was lucky enough to get some early samples of the new Panavision IR ND filters. I tested them here on both the Alexa and the Ursa Mini 4.6K.
You can see the Ursa Mini 4.6K is much more susceptible to IR pollution in this torture test under tungsten lighting.
I also compared the Schneider IR filters and you can see in the above link they really don’t measure up, whereas the Panavision IR’s look really great and were very consistent across their range. I went onto use the Panavision IR ND filters for the movie and I thought they were great and really consistent.
Up until using them on this film, I’ve pretty much only used the wonderful Mitomo TRUE ND’s, but as some will know these are obscenely expensive and hard to come by.
Well, I recently discovered, much to my pleasant surprise, that you can now BUY the Panavision IRND filters, because they’re made by Lee, and Panavision own Lee. And they’ve just started to sell them to us the general public !
Lee call these “ProGlass Cine IRND filters”.
Here’s the official page from LEE.
And here’s the official Panavision page.
And just to make sure they’re the same filters I checked by camera testing them!
So here’s a quick exterior IR filter test. I shot using the Alexa Mini, shooting ProRes 4444 Log C 1920.
I shot the Panavision IR filters, my new LEE IR filters (which should be the same) and some Tiffen IRND’s as a comparison, along with the Alexa Mini’s own internal ND.
Below is a little edit of the 2.1 ND in all situations, so you can compare. I was surprised how well the Tiffen did actually, as I’ve seen them be a lot worse. The 2.1 ND is a real test because at that density you generally see lot’s of variation in colour and consistency. As an extra check I’ve also shot using no filters at all.
