Once the input images are loaded, the interface presents you with a 100% preview of the result. The selected pixels from each input image are painted with a different color. You can then pan the result to inspect it.<\/p>\n<p>This tool also offers a bottom toolbar that allows to remove &#8216;ghosts&#8217; from the resulting image. Once the preview is satisfactory, the Save HDR option of the File menu generates the output DNG file.<\/p>\n<p><b>Install HDRMerge in Ubuntu 14.04:<\/b><\/p>\n<p>Press Ctrl+Alt+T on keyboard to open terminal.
