I shot this last night on the Big Four Bridge Ramp as the sun was setting. The evening was balmy and people were out enjoying the sunset and strolling along the bridge.

Processing was done on NIK HDR Efex Pro 2 and Aperture 3. There are three frames here that were merged at 100% anti-ghosting setting which eliminated the problem of shooting people moving during the three exposures. I also had to use the underexposed image as the reference image before I managed to get the people de-ghosted. I learned that when applying anti-ghosting it may take several tries before I can get the results I’m looking for. In this case I first used the  0 ev exposure at 20% anti-ghosting but it didn’t stop the ghosting. I then ran through the rest of the settings 40%,60%, 80% and finally 100% but there were still ghosted figures I then switched my reference image and that eliminated the problem.

Once the people started using the bridge on opening day it went from a static thing to a living structure. I was surprised how much difference I saw once people were walking on the ramp and bridge. Having that many people up there really helped add some scale reference to things. Before that moment I knew how big it was but without people on there it was hard to get a feel for what a massive structure the ramp and bridge really is.

This image is another bracket set of three frames shot at -2, 0, and +2 EV and merged in NIK HDR Efex Pro 2 then finished in Aperture 3.  I first tried the merger at 20% anti-ghosting and nearly all the figures were distorted so I returned it to the merge setting and boosted the anti ghosting to 60% which solved the problem and gave me the results I was looking for.



I shot this image last night just as a storm front was passing through Louisville. I shot seven brackets E.V. +2, +1, 0, -1, -2, -3, -4 in order to capture the full range of tonality in the scene. As I have said before I watch my histogram closely to be sure that I have no blown out highlights which for this scene required four stops underexposure.

I processed these frames in both NIK HDR Efex Pro and NIK HDR Efex Pro 2 and discovered that the later version, NIK HDR Efex Pro 2, is superior in it’s anti-ghosting capabilities as well as it’s tone mapping. I used the Realistic (Deep) preset and adjusted the tonality slider slightly while in NIK HDR Efex Pro 2. I then returned the image to Aperture 3 where I tweaked the vibrancy slider and then sharpened the image. After this morning’s experiment I am sold on the upgrade to NIK HDR Efex Pro 2 and recommend it for anyone wanting to process bracketed HDR images.
