Whenever I’m on a job site I keep my eye open for interesting patterns and textures to shoot as closeups or macro images. On this particular day I was on the job site to capture a large crane that had been brought in for a pick that night. I was scouting for good vantage points to capture the crane at work that evening when I came upon these retaining wall straps in the material storage area. I was intrigued by the surface texture and the undulating pattern that they revealed so I took a few bracket sets to work with later.
I almost always work in HDR and I decided to merge three frames in NIK HDR Efex Pro 2 and experiment with them. For this first image I applied the Balanced Preset and then boosted the definition to enhance the texture of the oxidized steel and reinforce the pattern. I included the long shadow in the upper left of the frame and the short shadow in the lower right side to create a sense of depth and movement in the final composition. After returning the merged file to Aperture 3 I adjusted the mid-contrast and boosted the  saturation and luminance in the red and yellow color channels. I then applied sharpening and a small vignette to complete the image.

I used a similar workflow for this image of the same straps that had been opened up and stacked for use. In this case I also worked in the blue color channel to contrast the blue and orange colors.

The final image is a Black and White version I created using Topaz B&W Effects and a Platinum preset. I also applied a white vignette and a frame from the same software before returning it to Aperture 3 for final contrast and sharpness adjustments.
