Last Wednesday the Ironworkers placed a 12 foot diameter, 127 foot tall caisson in the pier near the Kentucky shore. It weighed over 170,000 pounds and was going in one of the deepest piers of the project. Watching them lift it from a horizontal position into a vertical position was amazing. It took two cranes to do it and the coordination required was incredible.

This HDR image is from a three frame handheld bracket set consisting of +2, 0 and -2 EV exposures. I took the three frames into NIK HDR Efex Pro 2 where I merged them and applied the Balanced preset. While there I set the Detail slider to accentuated and the Drama slider to deep. In order to suppress some serious halos that were showing up along the vertical elements in the sky I reduced the Method strength slider until the halos were gone. I then took the merged file back into Aperture 3 for final adjustments to colors, sharpening and contrast.

 

HDR Construction Images of a Morning in November 2013

Today’s post is rather long on images yet short on words. I decided that what I wanted to show my readers was a series of several HDR construction images from a morning in November 2013. I thought sharing these HDR images from a single morning shoot would help my readers see how busy things are on the Ohio River Bridges Project.

I am always amazed at the skill and expertise that is required to do the work of Heavy Highway and Bridge Construction. Ironworkers, Carpenters and Operating Engineers must choreograph so many moves into placing the pieces of a single pier. The skill and commitment  to safety that they use to get the massive components in place is a sign of their professionalism and dedication to their respective trades. Any miscalculation when handling these pieces could result in slowing or stopping construction or even worse the very real possibility of the loss of someone’s life. For that reason the attention paid to properly performing each element in the process is paramount to safely accomplishing the task at hand.

I hope these HDR construction images help reveal the size and scope of the Ohio River Bridges Project as well as the my admiration for the skilled tradesmen and tradeswomen who perform these critical tasks. I also hope that the next time you see a construction site or meet a construction worker you will see their contribution to our way of life and the valuable part they play in building the world. Maybe you’ll even have a little more understanding of the important role that organized labor plays in providing skilled professionals that construct safe and dependable infrastructure for our world.

One final note about these images. All of the images in this post were created from three exposure bracket sets of +2, 0 and -2 EV exposures. They were merged in NIK HDR Efex Pro 2 and finished in Aperture 3. I use NIK HDR Efex Pro 2 because it does the best job I have found of reducing, and in most cases eliminating, ghosting when working with active subjects such as the men and women in these images. I finish the merged images in Aperture 3 because it allows me to control all the other variables such as color, contrast, sharpening etc in a non-destructive workflow.

Howdy everyone. It’s been weeks since I last posted about my ongoing project to chronicle the progress of the Ohio River Bridges Project here in Louisville. I’ve been quite busy with several other aspects of my personal project of photographing the bridge building process and the men and women who are building it. When I began this project I had no idea how truly monumental and time consuming it would be.

The last bridge/construction project I worked on was much smaller and didn’t fully prepare me for the scope of a major civil engineering project such as the Ohio River Bridges Project. When I photographed the Big Four Pedestrian Bridge and the men who did it I was working with a crew that numbered less than thirty people. In contrast the Ohio River Bridges Project involves not only the main span across the Ohio River but also a complete realignment and reconstruction of the area known as Spaghetti Junction. A project of this magnitude requires hundreds of people to accomplish and really expands my personal involvement. In Spaghetti Junction there are over fifty bridges and overpasses that will be needed to connect the new bridge to the Interstates that converge in Louisville. While the downtown span will carry northbound I-65 it must also join I-64 and I-71in Spaghetti Junction.

I have had to learn how to pace myself and how to best record the progress being made. In addition to the photography challenges I face there is the need to catalog, process and organize the thousands of photographs that I have already taken. Over this past winter I discovered that I needed to greatly expand my storage equipment to accommodate the massive amount of images I am recording. I had to upgrade several hard drives and take control of the photos or face utter chaos as the project grew. I thrive on challenges and this project has been the largest challenge I have faced as a professional photographer.

I lost the first two months of 2014 to personal health issues that prevented me from getting out to the job site as much as I wanted. I also had to contend with the extreme weather that gripped Louisville and slowed the construction. That is all past me now and I’m back to shooting regularly. I have upgraded my storage media and improved my workflow to allow me to capture the images I need to tell the story.

This week I was able to get out on the river and survey the progress that has been made getting the piers drilled and in place. The northern tower is progressing well and the tower crane is being assembled on it. The two towers that make up the northern tower are already taking shape and it was possible for me to climb up the western one and get the image that begins this post. In the weeks to come I will be climbing higher on these towers to shoot the Ironworkers and Carpenters as they build them.
