How to take a image with a best intensity resolution?

I have a basler camara that it has a intensity resolution of 12 bits but when I use the function "getsnapshot" I get a uint8 image. What am I doing wrong?

You're probably using the wrong video mode. What video modes show up in imaqtool? Is there one that says something about 12 or 16 bits?

Hi! Thank you very much for your answer. My video mode show me this:

    InstalledAdaptors: {'matrox'  'winvideo'}
          MATLABVersion: '7.14 (R2012a)'
            ToolboxName: 'Image Acquisition Toolbox'
         ToolboxVersion: '4.3 (R2012a)'

Imaqtool doesn't show anything like 12 or 16, but on the other hand the basler software permits to change between 8 or 12 bits.

Contact Basler or the Mathworks to find out why the Basler adaptor doesn't show up in imaqtool. If it doesn't show up there first, then no matter what you do in your program, it's futile.
