Beyond the BackyardCircle B Bar ReservePhotography Tips

Order Matters

Lately I’ve been playing with Photomatix and HDR.  I went back to a sunrise panorama that I did at Lake Hancock at the Circle B Bar Reserve.  Each portion of the panorama was bracketed for HDR.  When I first processed it with Photoshop, I did the HDR on each frame individually, taking care to apply the same settings to each frame.  When I stitched them together as a panorama, the colors weren’t right.  The sunrise circles weren’t right around the trees.  When I reprocessed it with Photomatix, it did the same thing.

So I tried again, this time doing the panorama merge with each exposure level, then applying the HDR.  The images didn’t line up perfectly with the second method, but Photomatix corrected it well.  The light distribution was better with the second way.  I definitely liked the Photomatix result better than the Photoshop one, and I think for sunrise and similar shots, where the light level is variable, it is best to stitch the panorama at each exposure level before applying the HDR.
