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.
