Description

nomacs is a free, open source image viewer, which supports multiple platforms. You can use it for viewing
       all  common  image  formats including RAW and psd images.  nomacs includes image manipulation methods for
       adjusting brightness, contrast, saturation, hue, gamma, exposure. It has a pseudo  color  function  which
       allows  creating  false  color  images.  A  unique  feature  of nomacs is the synchronization of multiple
       instances. With this feature you can easily compare images by zooming and/or panning at the exactly  same
       position  or  even  by  overlaying them with different opacity.  nomacs is licensed under the GNU General
       Public License v3 and available for Windows, Linux, FreeBSD,  and  OS/2.  It  is  free  for  private  and
       commercial use.
