Exposures

When working on paintings from my digital photographs, I often take the photo, make a copy and overexpose it. The original picture I adjust to give me the best visual look of the photograph in general with nice rich darks tones. The copy is then overexposed allowing me to see important details in the dark areas that aren't visible in the first photo. The second picture makes a poor photograph but often gives me clues to details I otherwise would totally miss in the first photo.
