On a photowalk last weekend (see previous post) I shot some frames in hopes of stitching a panorama of the Austin Skyline as viewed from the SRV statue on Auditorium Shores. I bracketed my shots with a mind toward using HDR and/or compositing to capture most of the dynamic range. I had no intention of filling in the deep shadows of course — It was getting dark after all.
In processing I set off to try the HDR route (I believe this is my first ever pano in HDR) and based on advice from Dave Wilson I first tonemapped the separate frames (3 exposures used for each) using the same settings in Photomatix. I used something on the order of 60% “strength” and tried to keep the HDR look toned down (FYI, the original exposures really do have this much blue in them). I tweaked the perspective of the individual frames a bit in Lightroom then merged to a panorama in CS5 using the ‘cylinder’ setting for the stitch. I could write an entire post about my perspective and stitching issues but suffice it to say that using the ‘auto’ setting was giving me very skewed perspectives from my wide-ish angle frames (30mm on a full-frame body). The automatic blending of the exposures after the stitch usually does a bang-up job of matching colors and creating a seamless stitch but I did have to manually tweak one area to make it match. Hopefully it’s not too noticeable…I won’t point it out of course. The HDR was a bit too saturated for my taste (it still kind of is…can’t make up my mind how I want this to look) so I used the vibrance adjustment to tone it down. Curves adjustments were used in various places for some final tweaks. No original exposures were masked into the final image.
Sunday night I enjoyed an evening photowalk with Todd Landry and several of the local “HDR Mafia” in Austin (Atmtx, Dave Wilson, Jim Nix, and Pete Talke) . I played around with some framing under the First Street Bridge and liked the sideways ‘V’ formed by the shadows under the bridge and on the water. I shot lots of brackets for this but I only used enough to give a hint of light under the bridge. I started down the path of masking in some of a lighter exposure but in the end preferred the deep shadow and how it draws more attention to the skyline and its reflection.
I tonemapped 7 exposures in Photomatix and blended pieces of the original exposures back in. This was followed by a few curves adjustments masked in here and there, selective sharpening, and noise reduction in much of the image. I had some chromatic aberration issues which I couldn’t get to go away via Lightroom adjustments so I used a trick I learned a while back: duplicate the final background layer, do a gaussian blur of 10-15 pixels, change the blend mode to ‘color’, and selectively mask into the problem areas. Works great for the most part but can cause a little of that blur to show sometimes.
We walked over to the SRV statue on Auditorium Shores to take some panoramas of the Austin skyline just after sunset. I got some cool shots but am frankly unable to get a stitch with a decent perspective (so far). I’ll keep working on that. Meanwhile, I decided to post a couple shots I took while the guys were shooting the skyline. Both were taken with my 50mm f/1.4 lens but I experimented a bit. One image used f/1.4 in order to get extreme bokeh while the other used f/8 to tone the bokeh down and show the skyline better.
