Carlos Herrera Posted May 13, 2019 Share Posted May 13, 2019 Hello friends! I was offered an awesome deal on a set of IRND filters, 180 bucks for a set of six 4.5.65's. However I noticed they weren't neutral, they tinted green on the image. Are these filters salvageable? Is there any hope of correcting the green tint with a LUT? The price is attractive, but I want to make sure I'm not buying junk. Thank you! Link to comment Share on other sites More sharing options...
Guillaume Cottin Posted May 13, 2019 Share Posted May 13, 2019 Any idea what brand they are? Link to comment Share on other sites More sharing options...
Bruce Greene Posted May 14, 2019 Share Posted May 14, 2019 Tiffen IRND filters had this effect. And it's not so easy to color correct them. Each density of filter has a different amount of greenish tint, and it seems that this green does not effect every color the same way. Maybe Tiffen has better IRND technology now, but I don't know. For a recent tiny project that we shot with a Sony A7RIII camera, I purchased IRND filters from https://breakthrough.photography/ And they were quite good, without a color cast. Though, in general, I do prefer to use a camera that has built in IRND filters matched to the camera sensor, such as the Alexa mini. I would conclude that the expense of color correcting these filters will be more expensive than the "bargain" on the used filters... Link to comment Share on other sites More sharing options...
