Long Exposure, HDR Images Of The Night Time Concrete Pour For The Plinth On Pier Four
This article is about using Long Exposure and HDR techniques to emphasize movement while taking advantage of high dynamic range photography.
Around The Ohio River Bridges Project – Abstracts and Closeups

These image are some closeups and abstracts that I shot last month while I was down shooting the Ohio River Bridges Project. Sometimes when I’m shooting construction I need to change my perspective by looking for abstract or closeup subjects. When I saw the concrete saws lying on a trailer I was intrigued by the pattern of the diamond cutting edges and the notches in the blades. The other image is from the tire tracks of a piece of rubber tired heavy equipment in sand.
I shot them in three frame bracket sets of +2, 0 and -2 EV exposures for later HDR processing. I processed the HDR images in NIK HDR Efex Pro 2 and Aperture 3. After completing the color versions I decided to use NIK Silver Efex to convert a couple of them to Black and White.

I-65 Southbound Section Was Nearing Completion
Click on the image to enlarge it in a separate window.
During the last days of construction of Phase One, Section One, of the I-65 Southbound Section, on the Ohio River Bridges Project the activity was fast and furious. There were areas that needed to be paved and concrete forms that needed building in order to stay on schedule and have it open for traffic by Sunday night.
In some of the following photos of the I-65 Southbound Section you will see areas that were almost completed and had the yellow and white traffic lane lines in place. In others the people were hard at work putting the finishing touches on their work.
Everyone was working long hours on the I-65 Southbound Section as the schedule was for 24 hours a day so the crews were constantly moving. In this group of photos you can see the amount of progress that was made in a single day. I was there early in the morning to catch the first light of day and returned in early evening to capture the progress and take advantage of the sunset light in the sky and clouds.
All the images in this post are HDR images from three frame bracket sets of +2, 0 and -2 EV exposures that were then merged in NIK HDR Efex Pro 2 and finished with Aperture 3. Using HDR techniques allows me to capture the broad dynamic range that exists at these times of day and to then use the tone mapping tools to reveal details in the shadows while also capturing the vibrance in the clouds and sky.

Sunset on the Ohio River Bridges
Click on the image to enlarge it in a separate window
Last night I decided to head down to the waterfront and shoot the Ohio River Bridges at sunset. The weather had been perfect all day and the forecast looked like there would be some clouds in the western sky around sunset. When I arrived at around 8:00 PM the sky was hazy and the clouds were still off to the west. I shot for a few minutes from Waterfront Park and then headed up onto the Big Four Bridge to watch the sun dip below the horizon.
Just before sunset the clouds moved in under the sun and I was able to capture the image above. By positioning myself on the Kentucky end of the Big Four Bridge I was able to frame the shot with the sun behind the tower crane for the Ohio River Bridges Project. I liked the way it was still above the Kennedy Bridge and the clouds created a beautiful orange glow across everything.
I shot with a tripod and captured a three frame bracket set of +2, 0 and -2 EV exposures. I processed the three frames into a single HDR image using NIK HDR Efex Pro 2 and applied the Balanced preset. I then returned the merged file to Aperture 3 where I adjusted it like I would normally. I boosted detail, added some contrast, adjusted color channels and sharpened it before cropping it to a wider format and adding a small vignette.

I was quite taken with the beauty of the colors in the sky and decided to shoot the Big Four Bridge while it was illuminated by the setting sun. The color of the light and the way it enhanced the rusted bridge really drew my eye. I also liked the way the sky and river transitioned from orange to blue and worked to strengthen that complimentary color scheme during processing.
I used the same techniques for this image as I did on the previous one which really saturated the colors and brought out the detail of the rusted ironwork and the reflections in the water.
