An optical artifact, this phenomenon manifests as unwanted streaks, circles, or polygonal shapes appearing in photographs. These artifacts are caused by light scattering and reflecting within the lens elements of a mobile device’s camera. A common example is the appearance of bright orbs when photographing a scene with a strong light source like the sun or streetlights.
Understanding this optical effect is critical for photographers using mobile devices. Recognizing the conditions that promote its occurrence allows for strategies to minimize or creatively utilize it. Historically, advancements in lens coatings and designs have aimed to reduce its prominence, although it remains a factor in image creation.
