Use flash from a distance
Depending on the situation of light, you should decide whether or not using camera flash is a good idea. Most mobile cameras have auto flash feature but I would suggest that you dont rely on it. Sometimes, camera may decide not to flash even though there is not enough light. So, you should explicitly use flash. But, while using flash, keep camera away from your face. Strong and sudden light from flash lamp can blind you if it flashes too close to your eyes.
