Understanding Sun Flare
First, understand what's happening. Sun flare is created when light from the sun enters your lens and bounces around internally between the lens elements. This internal reflection causes:
* Reduced Contrast: The overall image appears washed out.
* Veiling Flare: A general haze or glow over the image.
* Lens Artifacts: Streaks, circles, or polygons of light appear in the image. These shapes are often caused by the shape of the lens aperture or internal reflections.
Strategies to Minimize Sun Flare:
If you want to avoid sun flare, here's what you can do:
* Use a Lens Hood: This is the simplest and most effective way to block stray light from directly entering the lens. Use the hood specifically designed for your lens.
* Position Yourself Strategically:
* Change the Angle: Even a slight change in your position can significantly reduce or eliminate flare. Experiment by moving left, right, up, or down. Try moving until something partially blocks the sun.
* Shoot in Shade: Obviously, if the sun isn't directly shining into your lens, you won't get flare. Use natural shade from trees, buildings, or even your own body.
* Use a Reflector: A reflector can bounce light onto your subject, allowing you to keep the sun behind them, minimizing flare.
* Use a Polarizing Filter: Polarizing filters reduce glare and reflections, which can help to minimize some types of flare. They also enhance colors and contrast.
* Use Spot Metering: Metering for the bright parts of the scene can cause the darker areas to be underexposed. If the sun is too bright, using spot metering can help you find the exposure that will not cause flare. This will also provide a better exposure for the majority of the image.
* Clean Your Lens: Dust, fingerprints, and smudges on your lens can scatter light and exacerbate flare. Regularly clean your lens with a lens cleaning cloth and solution.
* Use High-Quality Lenses: More expensive lenses often have better coatings designed to minimize internal reflections. This is a long-term investment for improved image quality.
* Avoid Wide Apertures (Sometimes): Stopping down your aperture (increasing the f-number) can sometimes reduce flare. This is because a smaller aperture can reduce the amount of light entering the lens, but this is not always the case. In some cases it can increase the flare. Experiment to see what works best for your lens.
Strategies to Embrace Sun Flare (Creative Use):
If you *want* to use sun flare creatively, here's how to control it for the best effect:
* Experiment with Different Angles: Play with the position of the sun relative to your lens. Small changes in angle can dramatically alter the shape and intensity of the flare.
* Choose Your Lens Wisely: Some lenses are more prone to flare than others. Older lenses or those with fewer coatings often produce more noticeable and artistic flare. Experiment with different lenses to find the look you prefer.
* Control the Intensity with Partial Obstruction: Use elements in the scene (trees, buildings, your subject's hand) to partially block the sun. This can create interesting beams of light and control the amount of flare.
* Shoot During Golden Hour: The soft, warm light of sunrise and sunset creates more pleasing and less harsh flare.
* Add a Touch in Post-Processing: If you want to enhance existing flare or add it artificially, you can use software like Photoshop or Lightroom. However, use this sparingly, as too much artificial flare can look unnatural.
Shooting Techniques (Combines Minimizing and Embracing):
* The "Hand Shield": Use your hand or a piece of card to block the direct sunlight from hitting your lens. Carefully position it just outside the frame. This can eliminate unwanted flare while still allowing the sun to contribute to the scene's lighting. Be very careful not to touch the lens with your hand.
* Flare Removal in Post-Processing: Take two almost identical shots: one with the desired composition including the flare, and another where you carefully block the sun with your hand just outside the frame (like the hand shield technique). You can then blend the two images in post-processing, using the clear shot to remove the distracting flare artifacts from the original shot.
In Summary:
* Minimizing Flare: Use a lens hood, clean your lens, adjust your position, consider a polarizing filter, and shoot in shade when possible.
* Embracing Flare: Experiment with angles, choose lenses that produce pleasing flare, and shoot during golden hour.
* Key takeaway: Practice and Experiment! The best way to learn how to control sun flare is to go out and shoot in different conditions. Pay attention to how your lens reacts to the sun and develop your own techniques for achieving the desired effect.
