Slugger Field Section of I-65 is Moving Along Well

These images are of the construction around the Slugger Field Section of I-65 for the Ohio River Bridges Project in Louisville, KY.

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.

This shot is looking east with the Big Four Bridge in the background. The iron structure the ironworkers are building will be placed inside one of the steel cylinders that are in the righthand side of the image. There is a completed one on the barge behind the one where they are working. The hexagonal piece on the end is a jig to align the steel rebar while they assemble it.

This image is a single frame that was edited in Aperture 3 and Topaz Adjust. I wanted to capture the early morning fog and the light as the sun was coming up. The early morning on the river is a peaceful quiet time before the sun gets up in the sky and the temperature starts rising.

Topaz Adjust will be 50% off ($24.99) from September 9th through September 30th with this promo code: septadjust Topaz Adjust is one of their most popular plug-ins and doesn’t go on sale very often so if you haven’t tried it yet this will be a great opportunity to get it and save some money as well. Topaz Adjust is one piece of software that I find indispensable in my work and have been using for years now.
