Seven Preventable Causes of Lens Flare

Lens flare, while sometimes adding a stylized effect, can be a significant problem in photography. Fortunately, many instances of unwanted flare are preventable. Key factors include the choice of lens, as different lenses have varying flare characteristics due to their coatings and design. Aperture also plays a role, affecting the size and sharpness of flare. Careful positioning of the light source within the frame can substantially alter flare intensity. The use of filters, especially lower-quality ones, can increase flare, and it's sometimes advisable to remove them if the sun is in the shot. Finally, maintaining a clean lens, free from dust, water, or scratches, is crucial, as these contaminants significantly exacerbate flare.
