  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Hot Mirror/IRND/Mirror ND Filter Matrix [Parts 1-4]

MX and IR??

MX and IR??

Thanks for posing this question TJ I was just wondering the same thing. I've been sending out my usual Formatt IR/ND combos with our MX Reds, but after looking at some of the footage, it almost seems to be too much correction now. Maybe time to just go back to using straight ND's?
Anyone do any in-depth testing on this subject?

This is a great thread. Has anyone done any research on the IRND filters and the new MX chip?

I don't use IR protection any more.
Anyone want to buy my Panchros?

Thanks Dylan for being so informative on this thread. I have been using the Tiffen Hot Mirror IRND .9 and IRND 1.2 with the Red Camera. After getting the MX upgrade I immediately noticed that filter drastically changes the colors of every clip. I then went back to standard Schneider filters without IR filtration and was much more pleased with the results. Ryan at Schneider Optics has always been so helpful with any filter question that I have ever presented and is a wealth of knowledge. I'm not sure that using just the regular filters is actually the correct solution. Ryan mentioned that ALL of the mirror/reflective IRND filters seem to be causing color shift changes and that Schneider is releasing the Platinum IRND cut filters very soon that will absorb the IR instead of reflecting the IR. I believe that the IR absorption filters may already be available from Tiffen. The problem is that the new sensors are so sensitive that in order to operate near the sensors sweet spot, it is nearly always necessary to shoot with ND filters in the mattebox. I hope to soon hear some of Reds input on this problem. Can we please get some support here?

Lonny,
I've never agreed with the work practice of a Hot Mirror (any brand) then being used with a varying degree of straight ND's. I've always felt you would be overcorrecting at ND 3-9 and probably under correcting at ND 1.2-2.4
I've always liked the Formatt IR/ND combo's and felt they were calibrated for the best results. I bought one of the first complete sets of Pancro IR/ND's on the market, and thought they were fine, my clients just never liked the mirror surface of them. They were prone to a lot of reflections and kick back. The MX is definitely trickier, as the built in IR cut seems to be more effective than the M model, but I still think it needs some help at ND1.2 or greater.
 
Anyone have experience using the Platinum series from Schneider? Filmtools only stocks it up to 1.2 ND strength, which is silly as that is when you only begin to need it. I suppose you could stack it with a normal ND .9 but for MX ND 2.1 isn't always enough. What to do... Seems the best solution for the moment is normal NDs with the Schneider Trucut but then you're going to be using three filters already and I've only got a three stage matte box, which means no room for diffusion.
 
Always rented filters but about to pull the trigger on my own set of IRNDs. My main concern being do the filters negatively effect camera's that don't necessarily need the IR filtering? I know it's hard to predict the future, but even with people saying they don't use IR on the MX, if I did would I be negatively effecting the footage or would it simply do nothing? (If I find out I'm wasting a few hundred dollars because it won't be necessary to IR filter in a few years thats not a big deal, but If I find out that these filters will be completely unusable because they wreck the image that's a different story!)

Adding to this, what happens to when you throw IRND's in front on film? (Can't find anything online!)
