Nikon NEF to Tiff

[brettdeegarrett]

I have a NEF file that I open in Nikon NX Studio and export using defaults as an 8 bit tiff
I am attempting to use Magick.NET to take the same NEF file and get a very close result as NX Studio exports. The image I get from Magic.NET is more yellowish and the black lettering of the words are not as black as what NX Studio exported tiff image.
I have tried a lot of different things based on searching the existing Discussions.
My Code:

public void ConvertNEFtoTIFFMagick(string inputFilePath, string outputFilePath)
	{
		MagickReadSettings readSettings = new MagickReadSettings
		{
			Format = MagickFormat.Nef,
			//ColorSpace = ColorSpace.sRGB
			//ColorSpace = ColorSpace.RGB
		};
		readSettings.SetDefine(MagickFormat.Nef, @"use-camera-wb", true); //true lightened up the image a bit
		readSettings.SetDefine(MagickFormat.Nef, @"no-auto-bright", false); //true darkened the background
		//readSettings.SetDefine(MagickFormat.Nef, @"use-auto-wb", true); //Not much effect true or false
		readSettings.SetDefine(MagickFormat.Nef, @"output-color", 2); // 0 Raw,1 SRGB, 2 Adobe RGB, 3 WideGamutRGB, 4 KodakProPhotoRBG
       // readSettings.SetDefine(MagickFormat.Nef, @"interpolation-quality",3); //-1 disabled 0 Linear, 1 Vng, 2 Ppg, 3 Ahd, 4 Dcb
		//readSettings.SyncImageWithTiffProperties= true;
		using (MagickImage image = new MagickImage(inputFilePath, readSettings))
		{
			// Set the output format to TIFF
			image.Format = MagickFormat.Tiff;
			//image.ColorSpace = ColorSpace.sRGB;
			image.Depth = 8;

			// Save the image as a TIFF file
			image.Write(outputFilePath);
		}
	}

Note: The image is captured using a "Nikon Custom" Picture Control. I have access to the c# object that was set the "Picture Control" on the camera and it includes a custom curve. I am trying to figure out if I need to somehow use this information to get the result I want.

3. testRawAllMagick.tiff

Those calls to SetDefine should not do anything. Have you tried to use DngReadDefines instead?
