Save image as uncompressed 16 bit greyscale TIFF file

Question

It's my first time working with images and I'm trying to save in Image as 16 bit greyscale tiff file that should look like 1 from the attached picture.

I've tried using img.Save(".\\\\MyFile\\\\myImage.tif",ImageFormat.Tiff); but the result was 2 from attached picture.

I've changed the save to

EncoderParameters eps = new EncoderParameters(2);
eps.Param[0] = new EncoderParameter(System.Drawing.Imaging.Encoder.ColorDepth,24L);
eps.Param[1] = new EncoderParameter(System.Drawing.Imaging.Encoder.Compression,(long)EncoderValue.CompressionNone);

//var ei = GetEncoderInfo(ImageFormat.Tiff);
var ei = GetEncoderInfo("image/tiff");
img.Save(".\\MyFile\\myImage.tif", ei, eps);

and because color depth cannot be 16 I only managed to obtain the result 3 from attached picture. Is there a way to save the image as uncompressed 16 bit grayscale tiff file without using other libraries?

Use OpenCV like:

cv::Mat rawData( height_, width_, CV_16UC1, (void*)pPicData_);
cv::imwrite(fileName_.toStdString().c_str(), rawData);
