NEF metadata

[aleyandre]

Hi,
I am trying to extract data from a NEF (Nikon RAW) file.
Using imagemagick command-line :
magick identify -verbose myfile.nef
I get detailed metadata such as:

Image:
  Filename: myfile.NEF
  Format: NEF (Nikon Digital SLR Camera Raw Image File)
  Class: DirectClass
  Geometry: 4644x3084+0+0
  Units: Undefined
  Colorspace: sRGB
  Type: TrueColor
  Base type: Undefined
  Endianness: Undefined

I am mainly interested in the properties part; exposure, fnumber, and iso.
Is there any way to get these data from Magick.NET ?

Thanks

You should be able to do this: image.GetAttribute("dng:exposure.time").
