FLASH

PROS for FLASH are adding light to dim light situations and freezing time and eliminating blur.
CONS for FLASH are disturebed subjects, ugly lightning, red eyes and also you get a dark background. It is a very good idea to take a picture with flash when you are gonna take a picture in the sunlight. Its a badly idea to take a picture with flash in the dark because your background turns dark. This picture is a great example of not using flash because if you had used flash the background would of been dark.
