Seven photos of 6-minutes at f/8 ISO 200 were stacked for a cumulative 42-minute exposure under a full moon at Paul’s Junkyard. A faint amount of light painting was used at an oblique angle down the side of the Volvo 122 on the left. The warm yellow of the desert sand against the cool cyan of the night sky was slightly enhanced using a curves adjustment in the LAB color space. This fast and effective Photoshop technique also helped bring out more hue variation in the green truck. Stay tuned for a step-by-step look at using curves in LAB.
