title: Creating tiff 16 bit images and jpg thumbnails from it
body: <p>I'm using magick++ to create 16 bit tiff images. They are monochromatic, so all three channels have the same values. Once the image is completed I create png or jpg thumbnails from it.</p>
  
  <p>I can visualize the tiff and png images in Imagej perfectly. The jpg images can be visualized in Imagej but they lose a lot of color levels.</p>
  
  <p>However, all the images (tiff, png and jpg) are black in another viewers like Gnome, Firefox, Imagemagick viewer or Shotwell.</p>
  
  <p>Why? How can I see the images correctly in every viewer?</p>
