Flash as a Fill in during day time


Bright sun can cause harsh light on faces, with deep shadows around the eyes or under hat brims. This shows up even stronger in the resulting photographs.

There is a solution, something that you can do immediately whenever you are faced with harsh shadows on a nearby subject. Nearly all digital cameras allow you to force the flash to fire in these conditions to fill in those harsh shadows. Some cameras have a “fill flash” setting of some sort, too, but all you really need to do is turn the flash on and use the “always on” setting. The camera then adds

flash to the dark shadows, opening them up and revealing your subject much better.

This works only for subjects that you are fairly close to, though the actual distance is affected by the power of the in-camera flash. Usually, fill flash works best at distances less than 8–10 feet. Pros often use accessory flash for added power to boost this distance. Fill flash limits the shutter speed and f-stop possible with digital SLRs (try using the P mode at first).

Although changes are subtle and not too drastic with and without flash but adding a flash has certainly brought up the exposure without making it too obvious. well, you can certainly make out which ones are with the flash !
