The surveyors on Walsh Construction’s Ohio River Bridges Project are a critical part of the bridge building process. Without them the whole project would grind to a halt. By continually measuring and checking the installation of the foundation components these folks assure that everything goes into place exactly as called for in the plans.
This image is a three exposure bracket set that was merged and tone mapped in NIK HDR Efex Pro 2 before being returned to Aperture 3 for final adjustment. By using HDR techniques I was able to handle the wide dynamic range that was present due to the strong backlighting of the sun in the clouds behind the surveyor.
