How to Black Out Eyes in Photoshop

How to Black Out Eyes in Photoshop

Turning someone’s eyes fully black for a Halloween-ready, unsettling effect takes more than just painting over them, since a flat black fill alone looks obviously fake. This tutorial builds in the transition to the eyelid, the highlight that gives the eye depth, and the small hair details that keep the whole effect believable.

Checking for Catch Lights Before Starting

The reflected points of light in a person’s eyes, known as catch lights, are essential raw material for the highlight this effect depends on later.

1. Zoom In and Check for Catch Lights

   Zoom into the eyes and look for visible catch lights, the small reflections of light sources like a softbox or reflector.

2. Choose a Different Image if Catch Lights Are Missing

   Choose an image with visible catch lights already present, since an image without them won’t produce a convincing result, or borrow catch lights from a different photo if needed.

Why Catch Lights Matter Before Starting

Without a visible catch light to work from, there’s no existing highlight detail to isolate later when building the depth back into the blacked-out eye. Confirming catch lights are present before starting saves the effort of attempting this technique on an image that can’t support a realistic result.

Painting the Eyes Black

A quick pass with a black brush over each eye, without worrying yet about the eyelid or surrounding hair, forms the base of the effect.

3. Create a New Layer

   Create a new layer above the photo for painting.

4. Paint Black Directly Over Each Eye

   Press D for default colors and paint black with the Brush tool over the entire visible eye, staying close to its edge without worrying yet about the eyelid or hair above.

Blending the Eyelid Into the Blackout With a Curves Layer

A masked Curves adjustment darkens the eyelid using its own existing color rather than covering it with flat black, which reads far more naturally.

5. Add a Curves Adjustment Layer

   Add a Curves adjustment layer and drag the midpoint down to darken the image.

6. Invert the Layer Mask

   Press Cmd/Ctrl+I on the Curves layer’s mask to invert it to black, hiding the darkening everywhere.

7. Paint White to Darken the Eyelid Transition

   Use a soft-edged brush to paint white on the mask over the eyelid area, darkening it gradually as it approaches the blacked-out eye.

8. Adjust the Curves Amount if Needed

   Return to the Curves adjustment and lighten it slightly if the transition ends up looking too dark.

Why Painting Black Directly Isn’t Enough for Realism

A flat black fill sitting directly on top of the photo doesn’t account for how the surrounding skin, like the eyelid, would actually look if the eye itself were genuinely black. Darkening the eyelid’s own existing color with Curves, rather than painting flat black over it, keeps that transition looking like real shading instead of an obvious paint job.

Using Channels to Find the Best Contrast for Highlights

Comparing the Red, Green, and Blue channels reveals which one shows the strongest contrast between the eye’s highlight and the rest of the eye, information needed to isolate that highlight later.

9. Open the Channels Panel

   Turn off the black paint and Curves layers so you see the original eye, then go to Window > Channels to view the image’s individual Red, Green, and Blue channels.

10. Find the Channel With the Most Contrast

    Compare each channel and identify the one, most often Blue, with the greatest difference between the eye’s highlight and its surrounding darker area.

11. Duplicate That Channel

    Duplicate the channel with the best contrast to work on separately.

Why the Blue Channel Usually Has the Best Contrast

Different color channels capture different amounts of contrast depending on the specific colors present in an image, and the blue channel most often shows the clearest separation between an eye’s bright catch light and its darker surrounding color. Checking all three channels rather than assuming one will work is what ensures the strongest possible source for isolating the highlight.

Turning the Duplicated Channel Into a Selection

Adjusting Levels on the duplicated channel exaggerates the contrast enough to load the brightest areas directly as a selection.

12. Apply Levels to the Duplicated Channel

    Press Cmd/Ctrl+L and darken the shadows while brightening the highlights to create strong contrast between the highlight and the rest of the eye.

13. Load the Bright Areas as a Selection

    Hold Cmd/Ctrl and click the duplicated channel’s thumbnail to load its brightest areas as a selection.

Painting In Realistic Highlights

With the highlight areas selected, painting white directly into that selection restores the depth that a flat black fill alone can’t provide.

14. Turn the Painted Black Layers Back On

    Restore visibility on the black eye layers created earlier.

15. Paint White Within the Highlight Selection

    Create a new layer above the black eye layers and paint white with the Brush tool, staying within the pupil area to avoid losing the black eye effect.

16. Mask Out Any Overpainted Areas

    Add a layer mask and paint black over any white that extends too far outside the intended highlight area.

Restoring Hair and Eyelash Detail Over the Eye

A small, hand-painted brush recreates any hair or eyelash detail that originally fell across the top of the eye, tying the blacked-out eye back into the rest of the photo.

17. Create a New Layer for Hair Detail

    Add a new layer above the existing work specifically for hair or eyelash detail.

18. Paint Small Strands With a Fine Brush

    Use a very small, hard-edged brush to paint in individual strands of hair, following the direction they originally fell.

19. Add a Few Small Highlights

    Paint a couple of small highlight strokes to suggest light catching individual eyelashes.

Blurring for a Seamless Blend

A light Gaussian Blur softens any remaining hard edges from the painted layers so the whole effect blends naturally into the photo.

20. Apply a Light Gaussian Blur

    Go to Filter > Blur > Gaussian Blur and apply a small amount to soften hard edges from the painted layers.

Why This Approach Works

Darkening the eyelid’s existing color with a masked Curves layer, instead of painting flat black over it, is what keeps the transition into the blacked-out eye looking like real shading. Using channels to find the strongest contrast between an eye’s highlight and its surroundings is what makes it possible to isolate exactly the right area to paint the highlight back into. Restoring small hair and eyelash details on their own layer is what ties the entire effect back into the rest of the photo, rather than leaving an obvious black patch sitting on top of it.

Final Thoughts

Between the darkened eyelid transition, the channel-based highlight, and the restored hair detail, blacking out someone’s eyes convincingly comes down to rebuilding several small pieces of realism rather than one flat effect. This same technique works on any portrait, Halloween-themed or otherwise, as long as the original photo has clear catch lights to work from.
