How to Expertly Remove Glasses Glare in Photoshop

As a seasoned Photoshop instructor, I‘ve seen my fair share of portrait retouching challenges. One of the most common and frustrating issues is undoubtedly glasses glare. According to a survey by the Vision Council, approximately 164 million American adults wear eyeglasses – that‘s nearly 1 in every 2 people. So if you regularly take portraits, you‘re bound to encounter subjects with glasses and the annoying glare that comes with them.

Glasses glare occurs when light reflects off the surface of lenses directly into the camera. It‘s most noticeable when the light source is bright and close to the subject‘s face, like a camera flash or window. The glare appears as distracting bright spots, usually white but sometimes colored, that obscure the eyes and ruin the portrait‘s intimacy. Unfortunately, it‘s difficult to avoid in the moment without special equipment like a polarizing filter.

But fear not – with a bit of Photoshop finesse, you can expertly erase glasses glare in post-production. As a photo retoucher with over a decade of experience, I‘ve honed techniques for seamlessly removing all manner of reflections and aberrations. Today, I‘ll take you through my 3-step process and share some pro tips along the way.

We‘ll harness the power of Photoshop‘s Layers, Blend Modes, Selection Tools, and Adjustments to zap the glare without a trace. By the end, you‘ll be armed with a reliable workflow for saving portrait shots spoiled by glasses glare. Let‘s dive in!

Step 1: Neutralize Color Cast with Brush Tool & Blend Modes

Glasses glare often has a subtle color tint from reflecting the subject‘s surroundings. Before we remove the glare itself, it‘s crucial to neutralize any color cast on the lenses so they match the portrait‘s overall tone. The Brush Tool, combined with the Color Blend Mode, makes quick work of this:

1. First, create a new blank Layer above your image.
2. Set the Layer‘s Blend Mode to "Color" using the dropdown in the Layers Panel. This special blending mode will let us paint over the color cast without affecting luminosity.
3. Grab the Brush Tool (B). For best results, choose a round, soft-edged brush. Size doesn‘t matter much since we‘ll contain our painting to the lenses.
4. With the Brush Tool active, hold Alt/Option and click the subject‘s skin to sample a color. Aim for a neutral, midtone area like the cheeks or forehead. Avoid very bright highlights or deep shadows.
5. Now simply paint over the color cast on both lenses. The Color Blend Mode will apply your sampled skin tone‘s hue & saturation while preserving the underlying shading. Resample and paint with different skin tones as needed to achieve a natural blend.

Pro Tip: For more control, sample skin tones from multiple areas (highlights, midtones, shadows) and paint with each on its own Layer. You can then adjust each layer‘s Opacity to fine-tune the color correction.

With our canvas primed, we‘re ready to tackle the glare head-on. Onward to Step 2!

Step 2: Make Precise Glare Selections with Lasso Tools

To remove the actual glare, we first need to select it. Making an accurate selection is key for seamless results. The Lasso Tools are my go-to for this task thanks to their flexibility:

1. Zoom way in on the glasses for a clear view. Aim for at least 200% magnification.
2. For organically shaped glare spots, grab the standard Lasso Tool (L). For glare with straight edges, use the Polygonal Lasso Tool instead.
3. Carefully outline one glare spot, then hold Shift and outline the other spot(s) to add them to the selection. To subtract from the selection, hold Alt/Option as you trace.
4. Once you‘ve selected all the glare areas, go to Select > Modify > Feather and enter 1-2 pixels. This slight blur helps the edges blend more naturally.

Pro Tip: For complex glare shapes, break your selection into multiple parts and add/subtract as needed. There‘s no shame in zooming to 400% or higher for surgical precision.

Take your time with the Lasso Tools to capture every nook and cranny of the glare. The more accurate your selection, the easier the next step will be.

Step 3: Match Glare Exposure with Levels Adjustment Layer

Now for the magic trick that makes the glare disappear. We‘ll use a Levels Adjustment Layer to tweak the glare‘s exposure until it blends seamlessly with the rest of the image:

1. Go to Layer > New Adjustment Layer > Levels. Click OK. A new Levels Layer will appear in the Layers Panel with a Layer Mask automatically applied from your active selection.
2. In the Properties Panel (Window > Properties), you‘ll see the Levels controls featuring a histogram and three input sliders. The histogram maps out the tones in your glare selection from black point (left) to white point (right).
3. Drag the middle gray input slider slightly left to darken the glare. Keep an eye on your image as you adjust. The goal is to shift the glare‘s exposure to convincingly match the rest of the glasses and portrait.
4. Optional: If the darkened glare looks flat, paint on the Layer Mask with a low-opacity black brush to restore hints of shine and dimension. Hold Alt/Option as you paint to toggle the brush to white for erasing.

Pro Tip: If you‘re having trouble matching the glare exposure with Levels alone, try adding a Curves Adjustment Layer (Layer > New Adjustment Layer > Curves) clipped to your Levels Layer. You can then fine-tune the luminosity with more precision by clicking and dragging on the diagonal line.

Voila! With just a simple Levels Adjustment, the distracting glare melts into the portrait:

To really scrutinize your work, toggle the Levels Layer‘s visibility on and off a few times. The glasses should look natural either way, as if the glare never existed. Nicely done!

Advanced Techniques & Considerations

The 3-step method I‘ve outlined is my tried-and-true approach for everyday glasses glare removal. But sometimes, you‘ll come across a case that requires advanced Photoshop sorcery. Here are a few bonus tips and techniques to keep up your sleeve:

• For stubborn glare with remnants of color tinting, try adding a Hue/Saturation or Selective Color Adjustment Layer. These let you shift colors and neutralize lingering aberrations.
• If the edited glare area looks "muddy" or textureless, reach for the Frequency Separation technique. By working on a dedicated High Frequency Layer, you can paint in realistic lens texture without compromising the underlying exposure fix.
• When the original image lacks enough clean lens area to convincingly paint over the glare, consider compositing a "donor lens" from a different photo. Just copy, rotate & warp a glare-free lens to align it with the problem pair.

Beyond technical execution, it‘s worth zooming out (literally and figuratively) to consider how glasses glare removal fits into your overall portrait editing workflow. I recommend tackling it early on, before skin retouching and color grading. That way, you‘re working on a "clean canvas" free of distracting reflections.

It‘s also important to note that not every single speck of glasses glare needs removing. As glasses wearers know, some glare is natural and expected. The goal of retouching isn‘t to create an artificially "perfect" image, but rather to tastefully enhance the portrait while maintaining realism. When in doubt, err on the side of restraint.

Putting It All Together (+ Glare Removal Cheatsheet)

We‘ve covered a lot of ground in our quest to conquer glasses glare in Photoshop. To recap, here‘s a quick cheatsheet of the key steps and techniques:

Armed with this workflow, you‘re well on your way to expertly eliminating glasses glare from your portrait photos. But the best way to master these skills is hands-on practice. Dive into your own image library and seek out portraits with glasses. Better yet, do a dedicated photo shoot with a bespectacled friend to generate glare-removal fodder.

As you work through more and more cases, you‘ll gain the confidence and keen eye to zap pesky glare without a second thought. And don‘t forget – you‘re not alone on this journey. The Photoshop community is vast and generous. Countless tutorials, forums, and courses are just a web search away, like the excellent "How to Remove Glare in Photoshop" lesson from Phlearn.
