Fill flash is a technique which is used to brighten up deep shadow areas, this applies basically outdoors and on sunny days or for brighter background or we can say backlit subject. we use fill flash along with the properly adjusted aperture and shutter speed to correctly expose the background, and the flash is used to lighten up the foreground.
Most point and shoot cameras include a fill flash mode that forces the flash to fire, even in bright light, but this has to be used manually done in case of DSLR's.
Using the full power of the flash may greatly overexpose the subject especially at close range. Basically, DSLR cameras allow the level of flash to be manually adjusted e.g. 1/2, 1/8, 1/16 & 1/32 power, so that both the foreground and background are correctly exposed.
The advantage of using a fill flash method is to maintain exposure in situations, like backlighting which exceeds the ability of the camera to handle the contrast of the lighting.
More natural looking results can be obtained only by using the flash in a way that the shadow could be reduced as much as possible. Fill flash method is most useful when photographing people because it hides most of the shadows, especially the very distracting nose or chin shadow. In this case the shadow is mostly hidden down below the nose and not noticed.
In the example below you can see that picture of subject has been taken but the problem is the high contrast and the shadow because of which the subject is not clearly visible and to make it possible we have to use the concept of fill flash with the help of flash we will be able to see the subject but the problem is after fill flash concept we can see in the figure- that the background is blown out and how to maintain that we will see now.Most point and shoot cameras include a fill flash mode that forces the flash to fire, even in bright light, but this has to be used manually done in case of DSLR's.

| Taken with Nikon D5500, lens 50mm @ f/1.8 without flash & with brighter background |
From the above image, we can see that the background is brighter than the subject and is creating a shadow and contrast in the image.

| Taken with Nikon D5500, lens 50mm @ f/1.8 with Fill Flash Technique |
From the above image we can see that how the brighter background than the subject has been adjusted with the fill flash technique leaving little amount of shadow and contrast in the image, this can all the more corrected using external flash and reflectors.
Bouncing a flash from a surface above the subject, such as a ceiling, creates the same downward direction but is a strategy which can be used indoors. When the flash is bounced to create directional flashing its role changes from "fill" to that of "key" light.
The decision to use flash or not in that situation, totally depends on how important is normal looking background and we want to message our photo, all depends on how beautifully you can present the scene.
Faces oriented towards the sun at midday will usually have dark shadows in the eye sockets due to the downward angle of the sun and care should be taken that the subjects are not to be blinded by the sun. The more ideal strategy for portraits is open shade or backlit which allows the subject to raise their face and eyes into the skylight without closing their eyes or making faces.
In sunny day backlight, the contrast is more, but on an overcast day, the problem is a lack of contrast. In overcast conditions adding flash will make the shadow all the darker.
The ideal solution in backlight is to expose to retain details in sunlit highlights and to use two flashes to illuminate the front shaded side and the second flash from a downward natural direction which looks more natural, rather than exposure with a blown out background.
