Precautions on Long Exposure Shoots

1. Close the eyepiece shutter to block any light from entering the viewnder.

2. When using extreme long exposure more than 5 to 10 minutes outside

in daylight, please take relevant precautions, e.g. avoid having camera and

digital back in direct sunlight.

3. Cover your entire camera with a Phase One lens wrap or similar light proof

material to eliminate stray light.

4. Remember that when you make a long exposure, the digital back will make

a black calibration after the capture of the same duration as the exposure.
