I spent quite a bit of time photographing this old truck for 3 months at the beginning of this year (2011). The fact that it was parked right near where my RV was parked made it all the easier. The cloud cover was really quite striking this particular evening.
Equipment: Canon 5DmkII and 17-40mm lens, tripod
Processing: 6 photo HDR. Raws were processed in Lightroom. HDR Efex Pro was used for the HDR processing. I had to go back to one of the original RAW files to blend in the sky because the HDR software was not able to handle the ghosting due to the clouds moving between exposures.
