These drill heads are used in the installation of the bridge piers that will support the two towers for the Downtown Span of the Ohio River Bridges Project in Louisville KY. The steel caissons behind them will be placed in the river and filled with concrete to create the foundation for the bridge.

I created this image from a bracket set of three frames shat at +2, 0 and -2 EV. The dynamic range was pretty wide due to the effect of shooting through the caissons to capture the Louisville shoreline. Using HDR shooting techniques and NIK HDR Efex Pro 2 I was able to create a high dynamic range image that shows the shoreline as well as the interior of the caissons.

Final Assembly of the Pier Reinforcement Structure

This image shows the pier reinforcement structure that will be taken out to the drilling platform in the background and installed inside a steel caisson  that has been drilled thirty feet into the bedrock under the river. The men are making their final assembly before rigging it to be lifted and inserted into the caisson the next day.

Once again I worked with a single frame from my bracket set in Aperture 3. I created a preset that I can apply to most of my shots from this day which will greatly speed up my processing for the entire shoot. Once I have my basic settings adjusted to suit my vision for the photo I create a preset that I can then apply to other images from the shoot and then adjust to fine tune a particular image.

This image is from the work barge where the ironworkers are constructing the reinforcement frameworks that will be placed inside the bridge piers before the concrete in poured. I processed it in Aperture 3 without any additional plug-ins.

This HDR image is a three frame bracket set +2,0 and -2 EV. I merged it in NIK HDR Efex Pro 2 and finished it in Aperture 3. The flares around the lights are from the f8 aperture which adds a star burst to almost all artificial lights; the way around it is to shoot with as wide an aperture as possible which will reduce it greatly.

This HDR image was created using the same procedure as the first. I was shooting from the Big Four Bridge looking  south west from a vantage point close to the Indiana side of the Ohio River.

Ironworkers Assembling an Iron Caisson

Ironworkers known as “Rod Busters” are seen here assembling a steel rebar caisson for the Ohio River Bridges Project in Louisville Kentucky. There is also a completed caisson in the background on the work barge. These caissons will be inserted into the steel cylinders that are in the right hand side of the image when those cylinders are placed in the river to build the piers for the new bridge. It was early in the morning and a fog bank was coming in from the east which diffused the light and lent an ethereal quality to the morning sunlight.
