When taking pictures of people on a bright sunny day, try to put them in a shady location to avoid harsh shadows.
If you have no choice but to shoot in the bright sun, then arrange your subjects so they have their backs to the sun.
This way you will avoid people squinting.
You will now be shooting into the sun, so use your hand to shade your lens from the direct sun.
As a bonus, when using this method on females you should have a soft light on your subject’s face and a very nice rimlight around the hair.
