Lens flare is a visual phenomenon that occurs when a bright light source—like the sun or a strong artificial light—hits the camera lens directly, scattering light and causing reflections within the lens system. It often appears as glowing orbs, streaks, or haze in your photo or video. While sometimes unwanted, flare can be used creatively to add atmosphere and emotion to a shot.
What Causes Lens Flare?
Flare happens when non-image forming light enters the lens and reflects between lens elements or the camera sensor. Here are the main causes:
- Bright light sources (sun, LED lights)
- Wide-angle lenses with many glass elements
- Low-quality or uncoated lenses
- Shooting without a lens hood
Types of Flare
Understanding the types helps you identify and manage them:
1. Veiling Flare:
A hazy glow that reduces contrast and saturation.
2. Ghosting Flare:
Visible reflections or orbs, usually in geometric shapes.
3. Starburst Flare:
Appears as a star-shaped light burst, common when stopping down the aperture.
How to Get Flare (Deliberately)
1. Shoot Toward the Light Source
Position your subject so the light (like the sun) is slightly off-frame. This creates soft, artistic flares.
2. Use Prime or Vintage Lenses
Older lenses or primes without modern coatings are more prone to lens flare and give a retro, soft effect.
3. Remove the Lens Hood
A lens hood blocks stray light. Removing it increases the chance of flare entering the lens.
4. Try Lens Filters
Certain filters, like starburst or diffusion filters, can exaggerate the effect.
How to Avoid Flare (When It’s Unwanted)
Sometimes, flare can ruin an otherwise perfect shot. Here’s how to prevent it:
1. Use a Lens Hood
This is your first defense. A properly fitted hood shields your lens from direct light.
2. Change Your Angle
Simply moving a few degrees away from the light source can eliminate the flare.
3. Block the Light Manually
Use your hand, a flag, or a matte box to physically block stray light from hitting the lens.
4. Clean Your Lens
Dust and smudges can worsen flare. Keep your lens spotless.
5. Upgrade to High-Quality Lenses
Modern lenses have anti-reflective coatings that greatly reduce internal reflections.
Flare in Filmmaking: Creative Tool or Technical Flaw?
In cinematography, flare is often a stylistic choice. Directors like J.J. Abrams use it to add energy, realism, and a futuristic vibe. However, overusing it can distract the audience.
Use lens flare strategically to enhance:
- Emotional intensity
- Dream sequences
- Sci-fi aesthetics
- Natural light scenes
Best Cameras & Lenses for Creative Lens Flare
If you’re chasing artistic flares:
- Canon FD lenses or Helios 44-2 (vintage lenses)
- Sony Alpha series with manual lenses
- Blackmagic Cinema Camera with open aperture lenses
For flare-resistant performance:
- Sigma Art Lenses
- Zeiss T Coated Lenses*
- Canon L Series
Conclusion: Should You Embrace or Eliminate Lens Flare?
Flare can be both a visual delight or a technical issue, depending on how you use it. Understand the science behind it, and you’ll be able to control it—whether to capture its beauty or eliminate its distractions.
