This HDR image of the Big Four Bridge in Louisville’s Waterfront Park was captured looking east over the Ohio River from the war memorial in Jeffersonville, Indiana. The morning was bitter cold and a weather front was moving in from the west just before sunrise. The clouds were a harbinger¬† Continue reading “Big Four Bridge Sunrise”

This image shows the Ohio River Bridges Project Downtown Span construction site looking south from the Indiana approach. The triangular form in the right hand side of the photo is the base for the western section of the north tower that will support the new bridge. Across from that form you can see the rebar structure that will also be formed and filled with concrete to build the eastern section of the towers. These two sections Continue reading “Ohio River Bridges Project Downtown Span Construction Site”

Yesterday morning was one of those mornings where getting up early really paid off. The temperature was 19 degrees with snow showers moving in from the west just before sunrise. The combination of the weather front and the cold temperature made for an incredible display of color as the sun rose. Continue reading “Ironworker’s Sunrise”

Yesterday morning I decided to shoot an overview of the Ohio River Bridges Project Downtown Span foundation progress. I wanted to show the entire river crossing foundation work that has been accomplished so far. I went up on the Big Four Pedestrian Bridge to get far enough upriver to capture the view from shore to shore where the bridge will cross the Ohio River. I knew I wanted a panorama so I shot with the final cropping in mind.

I used a three frame bracket set of +2, 0 and -2 EV exposures that I merged in NIK HDR Efex Pro 2 and finished in Aperture 3. Currently most of my HDR work is being sent back to Aperture after very minimal tone mapping in NIK HDR Efex Pro 2 using the Balanced preset as my starting point and then adjusting exposure, contrast, highlights and shadows in Aperture 3. I also adjust the individual color channels and sharpen in Aperture 3 as well as cropping the image to the final size proportions.

Concrete Pour Equipment

This image shows the concrete pump boom transferring concrete to a pier pour in the middle of the river. The concrete is first transferred from the delivery trucks to the concrete pump which is sitting on shore. The concrete pump then pushes the wet concrete through the large pipe on the boom to the concrete placement workers who direct it’s placement in the concrete form in the river.

I chose this composition to emphasize the length that the material must be transported in order to make the piers in the river. I shot a three frame bracket set of -2, o and +2 EV and then processed the final image by merging them in NIK HDR Efex Pro 2. After merging them and applying some basic tone-mapping adjustments I returned the image to Aperture 3 for final processing.

In this image the vibrator operator is using a control box he is wearing around his waist to vibrate the wet concrete and eliminate any air pockets that may have formed as the concrete was placed in the form. The metal rebar that he is standing inside will connect the next pice of concrete to this base after additional forms are attached as the tower base rises out of the river. This particular concrete pour required 53 truck loads of concrete, 537 cubic yards of material, and took nearly an entire workday to complete.

This image is also a three frame bracket set processed with NIK HDR Efex Pro 2 and Aperture 3.
