Lens Flares

Definition

Lens flares are optical artifacts that occur when light is scattered and reflected within a camera lens, creating bright spots or streaks in an image. These effects can enhance visual storytelling by adding a sense of realism or drama, often associated with bright light sources, such as the sun or artificial lights, and can be deliberately used for artistic expression in film and photography.

5 Must Know Facts For Your Next Test

1. Lens flares can be categorized into two types: ghost images, which appear as circular shapes or spots, and streaks, which extend outward from the light source.
2. The intensity and shape of lens flares can vary based on the type of lens used, its design, and the aperture setting during shooting.
3. Flares can be unwanted distractions in some cases, but filmmakers often embrace them for their stylistic qualities, particularly in genres like sci-fi and action.
4. Post-production software can simulate lens flares if they were not captured during filming, providing creative flexibility in visual effects editing.
5. Different camera settings, such as aperture size and focal length, can significantly affect how lens flares manifest in a shot.
