These Ironworkers are setting the rigging to pick this caisson and right it so that it can be lowered into the casing for final placement. To lift it two cranes must coordinate their actions so that the main crane can upright the assembly and transfer it from the barge to the pier casing. Photo Tip: Having the men in the photo helps give scale to the size of the structure.

Once more this is a three bracket set of exposures using -2, 0 and +2 EV to capture the broad dynamic range between the sky and the foreground I encountered. This is one of the most important reasons to learn and use HDR techniques so that in a situation like this there is a reasonable chance that there will be enough data to create a good image after merging the exposures.

I used NIK HDR Efex Pro 2 and Aperture 3 to merge and process the image.

This second image is not an HDR image. There was too much movement of the cables and hooks, between frames in the bracket set; for the anti ghosting to handle in NIK HDR Efex Pro 2. I decided to take the normal (0 EV) exposure into Topaz Clarity to see how well it would do with the wide dynamic range. All in all I am fairly pleased with the way that I was able to bring out some shadow detail and still hold the sky detail using a single exposure. I know some folks like to take the normal exposure and change the exposure value in subsequent copies for a faux HDR look but I don’t go that route since there isn’t any additional data captured as there is when a bracket set is used.
