This tutorial will show you how to use the Lens Flare filter to create sinister B-movie glowing eyes (AKA the Evil Eye) effect in Photoshop.
[Step: 1] First, I’m going to darken the image using the gradient map. So, Open your image (ctrl +o), go to Layer > New Adjustment Layer > Gradient Map and change the gradient to black to white.
[Step: 2] Now change the layer mode of your ‘Gradient Map 1′ layer to ‘Multiply’
[Step: 3] You can duplicate your ‘Gradient Map 1′ to make the image even darker.
[Step: 4] Duplicate your background layer, and place it on top of the stack of layers
[Step: 5] Now select you ‘Background copy’ layer, go to Filter > Render > Lens Flare. Choose the 105mm prime option, set the Brightness to 100 and position the flare over the subject’s pupil.
[Step: 6] Repeat the Step 5 one more time to add a flare effect to the other eye
[Step: 7] Add layer mask to your ‘Background Copy’ layer, set your foreground color to black
[Step: 8] Click on your layer mask, choose a brush tool, set the brush size, play with the opacity, and start painting on the image to reveal the darkened image we did earlier.
