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.

Lowering the Caisson into the Pier Casing

This HDR image shows the 60 foot long caisson as it is being guided, by the Ironworkers and Carpenters, into place inside the pier casing. After placing the caisson the next step will be to fill the pier with concrete. The steel casing sits on the river bottom and then the caisson fits into a rock socket has been bored 30 feet below the casing into the bedrock of the river bottom. This makes the total length on the pier nearly 60 feet from the surface to the base. The iron cylinder is there to both guide the drill during drilling and to form a protective shell for the pier once the bridge is built.

This image is from a three frame bracket set using -2, 0 and +2 EV settings. I merged the bracket set in NIK HDR Efex Pro 2 and because the workers were moving quite a bit I had to apply 80% anti-ghosting to isolate them and remove the ghosts of their arm movement. After merging and some mild tone-mapping in NIK HDR Efex Pro 2 I returned the merged file to Aperture 3 where I completed my processing by adjusting contrast, alignment, sharpening and the individual color channels to achieve the look I wanted for the final image.

This image was taken from the Big Four Bridge looking west over Waterfront Park and the Ohio River in Louisville Kentucky. It was a busy morning on the river, the construction tug was moving barges for the Ohio River Bridges Project, the Belle of Louisville was headed upriver and a tugboat was pushing the largest size tow downriver, five barges long and three barges wide, that can go through the McAlpine Locks at one time. The Ohio river carries more traffic than any river in America delivering cargo from Pennsylvania in the northeast to the Mississippi River in the west and vice versa.

I decided to make this image Black and White after merging it in NIK HDR Efex Pro 2. I first took it into Aperture 3 after merging my three frame bracket set where I applied some additional contrast and a vignette to the HDR image before opening it in Topaz B&W Effects 2.1 where I chose the Platinum preset. I adjusted the paper tone slightly as well as adding some additional contrast adjustments that the Topaz B&W version seemed to need.

This image was captured looking west from the Big Four Bridge. The two cranes in the river are drilling sites where the towers for the Downtown Span will be built. The tugboat in the foreground was moving barges into place at the two drilling sites.

The image was created from a three frame bracket set of +2, 0 and -2 EV shot handheld. I merged them in NIK HDR Efex Pro 2 and applied the Balanced preset which I then tweaked to get the detail and realism I was looking for. I set the anti-ghosting at 60% which did a good job of rendering the moving tugboat. After merging and tweaking the image I returned it to Aperture 3 where I finished adjusting the color channels, contrast and sharpening.

The position of the hook and the man’s shadow on the rust colored sheet pilings really drew my attention. I processed this image with Topaz Clarity and Aperture 3 to enhance the texture and colors while maintaining the warmth of the early morning sunlight on the scene.
