Marcel Zyskind Posted May 19, 2005 Share Posted May 19, 2005 Hi I have raised this problem before, but I'll try again, maybe someone got the answer now that this camera has been used for some time. I like to use nd's in front of the lens, but I've had this problem with the colors going off, the blacks going dark red or purple when using heavy nd's in front of the lens. It is not correctable in telecine. I have also seen this on the xl1 some time ago. I have never seen it on the pd150 though. I have been using tiffen filters. Someone suggested that I should try Schneider filters, but I have not have had time to test them yet. I have also heard of mirrored nd's, but have not had the chance to try these either. I would like to source this problem, since I start production on a film soon, where we will be shooting in harsh sunlight and I would like to use nd's in front of the lens. Many thanks Marcel Link to comment Share on other sites More sharing options...
Premium Member David Mullen ASC Posted May 19, 2005 Premium Member Share Posted May 19, 2005 I've never had that problem so I can't help you. You shouldn't have problems using ND.30 to ND1.2 filters, even if they don't use "water white" (or is that "white water"?) glass. Any heavier, or stacking them, you may start to have problem.

Premium Member drew_town Posted May 20, 2005 Premium Member Share Posted May 20, 2005 I've never had that problem either. I've shot with a wide range of Tiffen ND's (from slight to heavy and stacked) with many different XL1s's, XL2's, PD-150's, and 170's. I can't think of what would cause that either. I've never used a DVX100 personally but know a handful people who have. They all use Tiffen filters, too. Might be an issue with the camera, something Panasonic or Tiffen needs to address. Does the camera work well otherwise? Link to comment Share on other sites More sharing options...
J. Lamar King IMPOSTOR Posted May 20, 2005 Share Posted May 20, 2005 I've ran into that problem and with Schnieder ND's. In my case it turned out the filters did have a magenta cast to them. If I white balanced, then pulled them guess what? A green cast to the picture. The DVX-100 did seem to be extra sensitive to that color shift and I don't quite know why.

Marcel Zyskind Posted May 20, 2005 Author Share Posted May 20, 2005 Hi Thanks for your replies! I've had a look at these water white nd's next to regular nd's and on the grads you can really see a difference in the glass, the water whites are much "cleaner" and the regulars have a slight green tone to them... Maybe that's where the problem lies. All the best Marcel Link to comment Share on other sites More sharing options...
Premium Member David Mullen ASC Posted May 20, 2005 Premium Member Share Posted May 20, 2005 The "green" problem is exaggerated and would barely be noticeable if at all. Link to comment Share on other sites More sharing options...
