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.

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.

The Ironworkers and Carpenters have been very busy over the winter and the North Tower of the Downtown Span is progressing well. In this first image you can see the tower base as it stands today. The Ironworkers are tying the rebar for the next section and as soon as that is done the Carpenters will form that section for the next concrete pour.

I regret that I was under the weather for the first two months of this year and unable to get out to the Ohio River Bridges project very often. In looking back at the images from the end of 2013 I can see that there has been a great deal of progress. I’m back on the job now and will be posting on a regular basis as I did throughout the end of summer and into fall.

All of these images today are HDR images processed in NIK HDR Efex Pro 2 and Aperture 3. As is my standard practice I shot everything handheld in three frame bracket sets of +2, 0 and -2 EV exposures. I applied 60% anti-ghosting during the merging of these three exposures and used the Balanced Preset as my starting point. After merging them and applying the preset I went back into the tone mapping settings and changed the Detail slider to Accentuated and the Drama slider to Deep. That is all I did in NIK HDR Efex Pro 2 before returning the merged file to Aperture 3 where I adjusted the color channels, sharpening, contrast and applied a small vignette.

In this image the Ironworkers are working with the crane Operator to lift more materials onto the tower scaffolding. They have to communicate with the Crane Operator using hand signals and radios to safely manage material transfers. I am always amazed at the skill of these crane operators to place everything from a small bundle of steel reinforcing to massive concrete forms on the job with pinpoint accuracy.

In this HDR image the concrete form is being removed from the angled surface of the eastern side of the eastern pier of the North Tower. The carpenters have unbolted it and rigged it for the crane Operator to lift it and transfer it to a waiting barge until it is needed again. Seeing the Carpenters alongside these forms gives scale to their size. Once again the Crane Operator and the Carpenters are working through radio and hand signals to safely move this massive piece of concrete form.

For this HDR image I chose to shoot the removal of the concrete form in a vertical format to better capture the cranes and the upward momentum that the project exudes as it progresses.

This HDR image shows both bases for the North Towers of the Ohio River Bridges Project Downtown Span. The progress that is being made really comes out in this HDR photo. The concrete forms have been removed from the base of the western side of the towers and scaffolding is surrounding the transition point as the base morphs into it final cylindrical shape which will be approximately 150 feet in the air when it is completed.

This HDR image shows a cooling manifold being lifted into place. It is used to distribute cooling water through the concrete as it cures. When concrete cures there is a lot of heat inside it; this is due to the catalytic reaction of the materials that are used to make concrete. Without cooling this reaction would cause the concrete to overheat and lose it’s strength. The cooling process goes on until sensors built into the structure provide the information to show that it is safe to stop cooling the concrete and allow it to finish curing.

I’m really glad to get back to shooting the Ohio River Bridges Project and posting my work again. I hope that small hiccup at the beginning of the year won’t be repeated and I can complete my project of documenting the Ohio River Bridges Project and the men and women who are doing it.

HDR Images of a Winter Day in The Parklands of Floyd’s Fork

This image is an HDR image captured in The Parklands of Floyd’s Fork in Louisville Kentucky. The trees and landscape were covered in ice which was creating a magical prismatic sparkle when the sun shown on them. I wanted to capture those colors and in making that attempt learned just how difficult that is.

As I reviewed the images back in my studio I could see faint hints of the colors that were being reflected as the suns rays diffracted through the ice but nothing was as spectacular as what I saw in person. I realized that my human experience was much more intense than my camera could record. Even with that discovery I’m still happy with these HDR images that resulted from that shoot.

I especially liked the way the sun was illuminating the tree line while a cloud was shading the foreground in this image. The reflections on the ice around the vegetation are a nice way to bring the light forward in the scene while still reinforcing the sense of cold in the photo.

This image is also HDR and I think it really shows how extending the dynamic range through shooting brackets for HDR, with a strongly backlit subject, can capture a broad enough dynamic range to render the scene.

When I’m shooting landscapes I like to include man made structures in the scene to show how they can exist in harmony with the natural environment. This bridge abutment with it’s strong geometric forms contrasts nicely with the flowing water of Floyd’s Fork. The bridge itself forma a frame to the sunlight’s reflection on the water. The railing along the top contrasts and reinforces the ice coated branches rising above it too.

This too is another case where the use of HDR technique in shooting, a three exposure bracket two stops apart, and HDR processing allowed me to capture information in the shadows as well as in the highlights. The extremely wide dynamic range of this scene could not have been captured as easily, if at all, with a single exposure. That is the main reason I totally embrace HDR photography even when I’m striving for strong realism in my images.

I liked this landscape because the sun was filtering through the trees creating a starburst of light while casting strong shadows across the landscape. As in several of these HDR images the HDR techniques of shooting and processing allowed me to capture the feeling of cold while gathering enough detail to make the image interesting.

I like the contrast of the complimentary colors of oranges and blues that are a major component of this composition. As in all of today’s images the use of HDR was the determining factor in the success of this shoot.

In closing today I’d like to say that whatever your feelings about HDR photography it has a place in photography. If you haven’t explored high dynamic range photography you are missing a valuable method that can open new vistas and expand your vision. Go on give it a try you too may find it is a wonderful tool that will allow you to express yourself in ways you have never before found possible.
