Before when I used to look at this picture i would just think, whoa, that flash is pretty bright, but now due to physics, I can finally understand why it is so bright. In most cameras, there is a capacitor which is used for the flash. It stores energy and then unleashes it all at one time and in this picture, I was caught by surprise when the camera's flash was so close to my face and I had to lean back because of its immense brightness. A capacitor is defined by two formulas, C=Q/V and C=kE(electric constant)A/D.
