¡ If the exposure obtained in step 3 is underexposed or overexposed, a
correct white balance might not be obtained.
¡ If an image was captured while the processing parameter was set to [B/
W] (p.59), it cannot be selected in step 5.
Instead of a white object, an 18% gray card (commercially available) can
produce a more accurate white balance.
