I forgot to mention that It all depends what file format your outputting. If your outputting to dpx or tiff then set the decode colorspace/gamma curve the same as RedcineX but in the write node set the colorspace to "linear". While working with the R3d though, the viewer will look different from RedcineX unless you set it to linear. After reading back in the dpx/tiff, then you can set the viewer back to srgb and it will look correct.
If your outputting to Exr from RedcineX then you need add a colorspace node with in:sRGB and out:Linear (Read node settings all should match RedcineX). While this is technically incorrect but it will give you the equivalent of burning the grade into the EXR. People here are mentioning using Half Linear Float which does properly linearize the curve form the chip when going to EXR. You would need to extract a lut between the linear R3d and your director's color to use as a viewer lut and use that in the write node. -deke On Tue, Dec 20, 2011 at 00:15, Ron Ganbar <[email protected]> wrote: > Thanks for this Deke. > The settings are all the same, but looking at the Nuke Viewer set to sRGB, > I see a very washed out image - what I would normally consider a Cineon > looking image.
