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.

Yesterday morning was one of those mornings where getting up early really paid off. The temperature was 19 degrees with snow showers moving in from the west just before sunrise. The combination of the weather front and the cold temperature made for an incredible display of color as the sun rose. Continue reading “Ironworker’s Sunrise” →

In the HDR image David Figueroa and Billy Baughman are monitoring the progress that David Morse is making on the drilling of this pier. They are close to the final depth and are clearing out the debris in the hole before taking measurements to determine if they are deep enough into the bedrock.

In this HDR image David Morse is measuring the depth of the drill shaft as his assistant and Oiler, David Figueroa , looks on. David is using a tape measure fitted with a weight, known as a plumb bob, that allows him to probe the bottom of the hole to attain accurate measurements. Once they are satisfied that the depth is correct they will clear the rest of the mud and rocks from the drilled shaft and turn it over to the Ironworkers who will place a caisson in the shaft in preparation for filling it with concrete.

Bothe of these images are three frame bracket sets using -2, 0 and +2 EV exposures which were merged in NIK HDR Efex Pro 2 and finished in Aperture 3.

Black and White Circles

I thought I’d try a little B&W Effects from onOne to see how this image would turn out. It was composed to capitalize on the idea of circles but the color version was just too flat due to the lighting that day. I applied an antique process preset but I don’t recall which one I used. I like the way the mood of the image conveys another era of photography while containing contemporary subject matter.
