8. To take pictures requiring long exposures of 2 seconds or more, set the
shutter speed selector to "B". The shutter will remain open for as long as
the shutter release button is held depressed so that you can trip the
shutter when you want to.
5. EXPOSURE COMPENSATION:
Under normal conditions your pictures will be properly exposed without
exposure compensation, but if you are shooting under special lighting
conditions (against the light, etc.), or if you are taking intentional
high key pictures (overexposed pictures) or intentional low key pictures
(underexposed pictures), or if you are taking pictures under the
conditions shown in the chart, exposure compensation is mandatory.
The procedures for making exposure compensation are as follows:
Press in the Film Speed Selector Lock and move the film speed setting to
+1 or -1. Be sure to move it back to its original position after making
your exposure.
Exposure Compensation with the Camera on Manual (Refer to the Paragraph on
Manual Exposure, Page 33.)
After checking the correct shutter speed indicated by the red LED in the
Viewfinder, turn either the Aperture Ring or Shutter Speed Selector to
increase or reduce exposure by the desired amount.
Exposure Compensation with the AE Lock (Refer to the Paragraph on AE Lock,
Page 29.) Set the Shutter Speed Selector to AEL and use the AE lock to
make exposure compensation.
