ABOUT LENS FLARE

LENS FLARE |
Lens flare is the
light scattered in lens systems through generally unwanted image formation mechanisms, such as internal reflection and scattering from material inhomogeneities in the lens. These mechanisms differ from the intended image formation mechanism that depends on refraction of the image rays. Flare manifests itself in two ways: as visible artifacts, and as a haze across the image. The haze makes the image look "washed out" by reducing contrast and color saturation (adding light to dark image regions, and adding white to saturated regions, reducing their saturation).
Flare is particularly caused by a very bright light sources either in the image – which produces visible artifacts – or shining into the lens but not in the image – which produces a haze. Most commonly, this occurs when shooting into the sun (when the sun is in frame or the lens is pointed in the direction of the sun), and is reduced by
using a lens hood or other shade.

one of the most
common causes of Lens Flare is the sun. Artificial lighting, such as strobe units, headlights and lampposts can cause lens flare especially when the lens is pointed directly at the light source. Lens Flare can also occur when you’re using your flash and reflective objects are present in the frame.

HOW TO AVOID LENS FLARE
One way to avoid Lens Flare is by using a
Lens Hood. Some lenses that are being sold in the market come with free lens hoods, attach the Lens Hood to your lens to avoid Lens Flares. If you don’t have a lens hood be resourceful and try to find an alternative like a cardboard or your hand to shield your lens from the sun or from the light source. Just make sure that your hood can’t be seen in the frame.
If you are using a Zoom lens and you don’t have a lens hood you can try changing your focal length by zooming in or out, this may help lessen Lens Flare and those polygon shaped sunspots. Though it can’t completely eliminate the Lens Flare, it will enable you to move and change the Lens Flare’s position to a less disturbing part of the image. Another way to reduce or avoid Lens Flare is by changing your angle or your shooting position in a way that the sun or the light source won’t directly hit your lens. This is one of the most effective ways of reducing or avoiding Lens Flare.
You can also try to recompose your shot and use or add different elements to reduce or avoid Lens Flare. Lastly, if you really can’t reduce or avoid lens flare, just give in to it and use it as a tool to make a delightful photograph.
