Hi all.

I have a question about the 16bit tiff image.  
[sample.tif](https://discourse.vtk.org/uploads/short-url/gw9RV2mdm8jT9OzMPmnVu6DqTrJ.tif) (144.7 KB)

If I load it on the ImageJ, the image shows from black to white value depends on the pixel value.

 ![imageJ](https://discourse.vtk.org/uploads/default/original/2X/6/64f3d16b40e05d79f80389695274044ed8b26f7d.png)

But if I load it on the VTK sample code, the image shows white regardless of the pixel value.

 ![sample code](https://discourse.vtk.org/uploads/default/original/2X/5/51cde6c6205c4add766043278d76b72cf7dcf4d1.png)

Sample code: [https://lorensen.github.io/VTKExamples/site/Cxx/IO/ReadTIFF/](https://lorensen.github.io/VTKExamples/site/Cxx/IO/ReadTIFF/)

Did I miss something on the code?

Could you give me an advice?

Thank you 🙂

Hi, Kim,

Have you tried other TIFs? For example the ColorCells.tif of the example?

Paulo
