People shots taken at the middle of the day can have harsh and unattractive shadows across peoples faces. Oddly enough, a good way to tame these shadows is to use your cameras flash, a techinque known as 'fill flash'
- Another person.
- A sunny day.
- Activate the flash on your camera. Cycle the flash until it says something like "Flash - always fire"
- Take a photo and playback the result.
- Likewise, if their face has become too white, reduce the exposure compensation. If that doesn't work then just move away from the person, zoom in and take another photo.
- Likewise, if there's still too much shadow, try increasing the exposure compensation. If that doesn't work then just move closer to the person.
