Stuart Allman Posted March 23, 2016 Share Posted March 23, 2016 Any recommendations on Formatt Firecrest ND filters vs. Mitumo TrueND filters? I'm never going to have Meryl Streep or George Clooney in front of my camera, but I am looking for an upgrade from my current set of Tiffen water white ND filters. I haven't found a direct technical comparison yet. I have a 4x5.65 matte box, so I can use either. BTW - the Tiffen 0.3-IR1.8 set is for sale. PM me if interested.

Premium Member Satsuki Murashige Posted March 24, 2016 Premium Member Share Posted March 24, 2016 I think it depends on what cameras you want to use them with and how each sensor sees IR. A lot of rental houses are providing Mitomo TrueNDs for everything, but Shane Hurlbut recently posted a test with the Red Dragon Standard OLPF where the TrueNDs came up green compared to non-IR Tiffen (I am assuming these are White Waters): https://www.hurlbutvisuals.com/blog/2015/11/reds-game-changing-olpf-filter-cinematography/. Still have not seen the Firecrests in person. Link to comment Share on other sites More sharing options...
Stuart Allman Posted March 24, 2016 Author Share Posted March 24, 2016 I mostly use Sony cameras, like the FS-7. I occasionally see a Canon camera, but that's about it. I don't plan on using the Red or Arri cameras. Mainly I'm looking for an opinion of whether the 2x price difference is really worth it for non-studio and non-broadcast work. I've seen plenty of favorable reviews of both products, but there has to be a gotcha somewhere, given the price difference. The Tiffen filters I have seem to work just fine with a custom white balance, but I feel like it might be time to upgrade to a more modern technology that handles color neutrality better.

Premium Member Satsuki Murashige Posted March 24, 2016 Premium Member Share Posted March 24, 2016 Do you normally use the internal NDs? I've only used the FS7 a few times, but I use the F5 and F55 a lot. With an internal 0.9 and 1.8, I only ever use my 4x5.65 White Water 0.3 and 0.6 anyway, so IR pollution is never an issue. Have never needed TrueNDs with internal ND cameras. Link to comment Share on other sites More sharing options...
Stuart Allman Posted March 24, 2016 Author Share Posted March 24, 2016 I use the internal ND's, but I noticed some magenta creeping into black fabrics last time we used tungsten lighting. It doesn't appear that the internal ND filters reject IR very well. Normally I use plasma or LED lighting, so it's not an issue, but we're back to using tungsten more often now. That's mainly why I'm interested in solving this issue with more modern ND filters. Trying to color correct excess red out of dark fabrics is very hard when your main talent is African-American with very dark skin. We do a lot of video production tutorials, so I might have the option of contacting the companies and asking for demo units if we do a video about them. Some companies are much more open and responsive than others. Stuart ---------------------------- illuma.blogspot.com Link to comment Share on other sites More sharing options...
Premium Member Satsuki Murashige Posted March 25, 2016 Premium Member Share Posted March 25, 2016 Interesting, it's true that I don't often use tungsten in combination with NDs. Generally it is HMIs. Some further testing is needed. If you do the test videos, please let us know the results! Link to comment Share on other sites More sharing options...
Stuart Allman Posted March 25, 2016 Author Share Posted March 25, 2016 If you take a look at our CRI tutorial you'll see that the HMI we were using doesn't have that much in the infrared spectrum. Tungsten has oodles of IR. Daylight has proportionally less than tungsten. https://vimeo.com/124724589 Stuart Allman --------------------------- illuma.blogspot.com Link to comment Share on other sites More sharing options...
