I. Before You Shoot (Best Practice - Prevents a Lot of Problems):
* Angle of the Subject:
* Have the subject angle their head slightly down and towards the light source. This moves the reflection area down onto the lenses and potentially out of the eye area. It's a subtle adjustment, but powerful. Experiment with both left and right angles to see what works best.
* Consider the angle of the glasses themselves. Tilting the glasses slightly can change the angle of reflection.
* Angle of the Light:
* Move the light source: Experiment with different positions (higher, lower, to the sides). The goal is to move the reflection away from the central part of the lens covering the eye.
* Diffuse the Light: Use softboxes, umbrellas, or diffusers to create a larger, softer light source. This will spread the reflection out and make it less noticeable. Large, soft light sources are your best friend. Hard, direct light creates harsh, defined reflections.
* Consider Polarizing Filters:
* Camera Polarizing Filter: A polarizing filter attached to your lens can cut down on reflections. Rotate the filter to find the sweet spot where it minimizes reflections on the glasses. Be aware that polarizing filters can also reduce light, so you may need to adjust your ISO or aperture accordingly.
* Polarizing Filter for Lights (Less Common): You can also use polarizing filters on your light sources, but this is less common and requires specialized equipment.
* Subject's Glasses:
* Clean the Lenses: Make sure the glasses lenses are spotless before shooting. Smudges and fingerprints amplify reflections. Use a microfiber cloth specifically designed for glasses.
* Anti-Reflective Coating: If possible, encourage the subject to wear glasses with an anti-reflective (AR) coating. This significantly reduces reflections. However, AR coatings can sometimes cause green or purple fringing, which you might need to correct in post-processing.
* Consider Removing Glasses: If it's appropriate for the portrait and the subject is comfortable, simply ask them to remove their glasses. This is the easiest solution, but not always feasible.
* Position Yourself:
* Move yourself! Sometimes a small adjustment in your position can make a big difference. Observe the reflections from different angles.
II. During the Shoot (Refine as you Go):
* Take Multiple Shots: Vary the angle of the subject's head, the position of the light, and your own position slightly between each shot. This gives you more options to work with in post-processing.
* Observe Carefully: Pay close attention to the reflections in the viewfinder or on the LCD screen. Make adjustments as needed.
* Communicate with the Subject: Explain what you're trying to achieve and ask for their cooperation.
III. Post-Processing (When All Else Fails):
* Healing Brush/Spot Healing Brush Tool (Photoshop, GIMP, etc.): For small, isolated reflections, the healing brush or spot healing brush tool can often work wonders. Sample a clean area of the lens nearby and paint over the reflection.
* Clone Stamp Tool (Photoshop, GIMP, etc.): Similar to the healing brush, but you have more control over the source area. Carefully clone clean areas of the lens over the reflections. Use a soft brush and low opacity for best results.
* Content-Aware Fill (Photoshop): Select the reflection area and use content-aware fill. This can be hit-or-miss, but it's worth trying.
* Frequency Separation (More Advanced - Photoshop): This technique separates the texture and color information in the image. You can then work on the color reflections without affecting the sharpness of the glasses. This requires some experience with Photoshop.
* Gradient Tool (Photoshop): If the reflection is a large, uniform area, you can try using the gradient tool to blend a clean area of the lens over the reflection.
* Masking and Layering:
* Take two shots: One with the best overall pose, and another where you've specifically manipulated the light to eliminate reflections in the glasses (even if the pose isn't perfect).
* In Photoshop: Bring both images into Photoshop as separate layers. Mask out the glasses area from the image with good pose and reveal the glasses area from the image with reduced reflections. This allows you to combine the best of both worlds.
* Specialized Plugins: Some plugins claim to automatically remove reflections in glasses, but their effectiveness can vary.
* Outsourcing: If you're struggling, consider outsourcing the retouching to a professional retoucher who specializes in portraits.
Key Considerations:
* Subtlety is Key: Avoid over-editing. You want to remove the reflections without making the glasses look unnatural or fake.
* Sharpness: Be careful not to soften the glasses too much during post-processing. Sharp glasses help maintain realism.
* Natural Light vs. Artificial Light: Natural light is often more forgiving than artificial light when it comes to reflections. However, you have less control over natural light.
* Practice: Experiment with different techniques and practice on sample images to improve your skills.
In Summary:
The best approach is to combine multiple techniques. Start with good lighting and camera angles to minimize reflections in the first place. Then, use post-processing to clean up any remaining imperfections. Remember to be patient and pay attention to detail. Good luck!
