Setting the Shutter Speed

When you set the shutter speed in the shutter speed-priority AE mode, the
camera automatically selects an aperture value to match the brightness.
Faster shutter speeds allow you to catch an instantaneous image of a

to shoot without a flash in dark areas.
If the image would be underexposed (too dark) or overexposed (too bright)
and the correct exposure cannot be obtained, with the shutter button pressed
halfway, the aperture value display on the LCD monitor turns red. Turn the
multi control dial to adjust the shutter speed and display the aperture in white
