 The rest of this tutorial describes generating high quality output using command-line

 something like this:
 # Take [[bracketing|bracketed]] shots of your scene.
-# Merge bracketed shots to [[HDR]] with [[qtpfsgui]], pick either [[RBGE]] radiance .hdr output or 32bit floating-point [[TIFF]].
+# Open bracketed images in Hugin. Align - let's say - the middle exposures together and set the stacks in the ''Images'' tab.
-# Stitch the panorama with [[hugin]] and [[enblend]].
+## If your stacks don't align (shot hand-held, sloppy panohead, etc.), set some control points inside stacks and align them too.
 # Optionally tonemap the result with [[qtpfsgui]].
