How to shoot in sunlight.

First, use ISO 80, not 100. You up the ISO only in situations where you're not getting enough light.

Second, if you're not in manual, decrease the exposure compensation (Ev).

Third, consider a neutral density of polarizing filter. These act like sunglasses for your camera.

The display button in review mode gives good feedback. Overexposed areas will flash. Also, auto-exposure bracketing will take 3 shots in a row at various exposures, making it easier to decide.

Few more steps,
Change the Priority mode to Shutter speed priority if you are not very comfortable with Manual mode and select an higher shutter speed to reduce the amount of light that hits the sensor.
