Important tips for better flash(闪光灯、闪光)photos

　　Don't stand too far back from your subject．The flash on most cameras will not cover any subject well over three metres away．Even in non-flash photos many photographers stand too far away from their subjects．As a result, the subjects are small with great areas of unimportant background．

　　Watch the background carefully and be sure there are no mirrors or shiny things to reflect(反射)the flash back to the camera lens(镜头)．

　　When taking pictures of people, ask them not to look into the lens but at a point over your shoulder, because it is very possible that the flash will reflect from their eyes and there will be red eyes in the photo．

　　Try to give the subjects an interesting background．If there is nothing for two metres behind the subject, the background will come out black or very dark．Of course, you don't want an untidy background, because it will take people's attention away from your subject．

　　If taking a picture of a baby, be sure the room is as light as possible so that the flash does not hurt his/her eyes．
