Before you start.

Use these sample images or practice with your own.

Step 1: Draw a shape

Using the Pen tool, Larson clicked three points to draw a triangle around the hand. You can draw any shape on your image and, with the new Shape layer selected, click the Add Layer Style icon from the Layers panel and choose Outer Glow.

Step 2: Create the glow

Experiment with different colours and settings for the Outer Glow. Larson settled on a vivid magenta. Then she set an Inner Glow, changed the Blend Mode to Multiply and applied the same magenta colour.

Step 3: Convert and mask

Larson right-clicked on the Shape layer and chose Convert To Smart Object. Then she added a mask to the Shape layer.

Step 4: Hide and reveal

Larson wanted to hide the triangle just behind the wrist. To hide parts of your neon shape, set the Brush tool to black, select the mask (the white icon on the layer) and brush to remove those sections. To reverse the effect, simply change the brush colour to white and paint on the mask to reveal detail again.
