7 Ways To Use Lens Flares For Film & Video
Using lens flares in photography, feature-length films, as well as short videos, has gained popularity since its emergence in cinema in the 1960s.
At the start of cinema, lens flares were a crime against the art. Most filmmakers, such as Orson Welles, used to coat their lenses in Vard ‘Opticoat’ to avoid creating lens flares. However, at the start of the 1960s cinematographers took a different approach. Films such as the 1967 film, Cool Hand Luke, made use of lens flares to add a sense of realism.

They wanted to prove to the audience that the film was not shot in a studio but was rather a product of the real world.
The trend caught on and by the 1970s filmmakers incorporated them into Science Fiction films. From there on, lens flares have become a sort of norm in both photography and film.
If you are an aspiring filmmaker or photographer who is interested in lens flares, you may want more control over the image at the start. Lens flare video effects that are edited in during the post-production cycle can help with this.
What Are Lens Flares?
Within the lens of your camera, many parts work to make sure that it can capture an image accurately. A lens flare occurs when the sun hits the lens and bounces around in these parts. The reflections of the light bouncing off the inner workings of your camera create circular shapes on the image. The more directly you point your camera towards the light source, the bigger the flare.
You’re probably thinking, what about the lens flares that you often see in films? These are more streaky and oval-looking.
These are anamorphic lens flares. They occur when the cinematographer makes use of an anamorphic lens, which is oval-shaped. The information in the image is originally crushed when using this lens. So when the image is converted to the regular image size, the flares come out as stretched and streaky.

An excellent example of this is the 2013 film Gravity.
3. Lens Flares Caused By Light
This is perhaps the most obvious method of using lens flares, however, it is still useful. In many films, a lens flare is used to depict the brightness of looking in the sun, or someone shining a light into a character’s eyes.

Another example is Birdman when Riggan Thomson attempts to kill himself on stage. The audience disappears behind a strong lens flare. Allowing the viewers to feel the isolation and desperation of Riggan at that moment.
Overusing lens flares can sometimes be overwhelming and take away the sense of realism it aims to create. However, sometimes that may be exactly what you wish to achieve. When creating a flashback or dream sequence, the filmmaker may want to create a sense of a dream world.
By using a few lens flares layered upon each other, you can create an opaque dream sequence. This may create a sense of being far away, which is exactly what you want to achieve.
