The adjusted exposure value will appear as shown below.
Once you adjust the exposure, the setting will remain the same. You 
may need to change the exposure value later to avoid overexposure 
or underexposure. 
If you cannot decide on an appropriate exposure, select 
AEB (Auto 
Exposure Bracket). The camera will take 3 consecutive photos, each 
with a different exposure: normal, underexposed, and overexposed.
