Overexposed highlight areas blink on mini-photo next to histogram. No detail recorded. Referred to as “blown out” areas. Just a warning. May need exposure adjustment.
Histogram Graphic representation of exposure from dark (underexposed) areas on left side to bright (overexposed) areas on right. Mid-tones in middle. Vertical axis equals pixel quantity.
Location of Features
Canon Rebel Xti: Go to LCD Playback Mode. Press display button. Press twice to find histogram.
Exposure CompensationYour meter bases exposure on average reflectance of objects,
which is 18%
What do you do for non-average scenes?
1. Overly bright scenes—e.g. white bunny in snow Add +1 to +2 compensation
2. Overly dark scenes—e.g. black cat in coal binSubtract -1 to -2 compensation

EXPOSURE COMPENSATIONPLUS/MINUS Button
Feature DescriptionAdd compensation for brighter exposure. Subtract compensation for darker exposure. To use, press button and rotate main dial. Compensation appears in viewfinder and LCD monitor. Reset after use.
Bright SubjectsWhite Bunny in
Snow
Meter underexposes very bright subjects. So add compensation in increments to get correct exposure. White bunny in snow, add +2 stops of compensation.
Dark SubjectsBlack Cat in
Coal Bin
Meter increases exposure on very dark subjects. So subtract compensation in increments. Black cat in coal bin, subtract -2 stops of compensation.
Feature DescriptionAEB Camera makes three consecutive exposures: standard
(based on auto-metering), underexposure, and overexposure. You set exposure amounts in increments of 1/3 stops. For average use, try 1 stop increments.
AEB with Continuous
shooting mode
Set motor drive on continuous shooting mode. Camera takes three consecutive shots at three different exposure values automatically. Review in LCD. Make adjustmentsas needed.
For Digital Editing
For scenes with high contrast, take three exposures as described above. In editing software, combine multiple exposures into one master image. Use tripod.
