Capture One introduced HDR merging in one of their recent releases [0].&lt;p&gt;It does raw in &amp;quot;raw&amp;quot; out. You get a DNG out which is demosaiced. I have not yet looked to see what it&amp;#x27;s doing under the hood, and how the result compares to EXR. (But in my experience, it seems to struggle with large exposure differences, even when on a tripod).&lt;p&gt;[0]: &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;support.captureone.com&amp;#x2F;hc&amp;#x2F;en-us&amp;#x2F;articles&amp;#x2F;4410014730257-HDR-merging-overview&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;support.captureone.com&amp;#x2F;hc&amp;#x2F;en-us&amp;#x2F;articles&amp;#x2F;44100147302...&lt;/a&gt;</text></comment>
