FrontFlash app uses iPhone 4's display as a flash for its front camera. It enables you to take better photos in low light conditions or even complete dark.

How it works?
• Use your screen as a viewfinder to frame the shot
• Tap anywhere to start timer and move your fingers off screen to get more light from it
• When timer goes off, entire screen will flash with warm light color that will light up your face or other objects and take a photo, then automatically save it to your Camera Roll

For best effect, turn off Auto-brightness in Settings/Brightness, and adjust it manually to higher setting before using FrontFlash, but make sure to set it back later to preserve battery life.
