How to Add a Point Light in Photoshop

 

 

In Photoshop you can add either Infinite, Spot or Point lights. Point lights are similar to the way that a naked light bulb lights a room. The rays travel from the bulb outward in all directions.

With Point lights and Spot lights you can add Falloff to your light to better simulate a real light. Falloff occurs as the light travels away from the light source. You can see this phenomenon whenever you observe head lamps on a car. The further from the car, the less intense the light.

 

Step One

In Photoshop open a new blank document (File > New). Set the image size to 1,024 pixels by 1,024 pixels.

Step Two

Add a new layer to the Layers panel by clicking the Create a New Layer icon.

Step Three

Choose 3D > New Mesh from Layer > Mesh Preset > Cylinder. The object is added to the blank layer and it becomes a 3D layer.

Step Four

In the 3D panel you can choose to see the Entire Scene, Meshes, Materials or Lights. Click the Lights icon.

Step Five

Click the Add Light icon at the bottom of the 3D panel and choose New Point Light.

Step Six

Click the visibility icon next to the Infinite light to turn the Infinite light off. At this point the only light illuminating the scene is the Point light.

Step Seven

Click-drag in the view box in the lower left corner of the workspace to frame your scene. Drag the light arrows to reposition the light.

Step Eight

The light's color is changed by clicking the Color rectangle in the Properties panel.

Step Nine

To change the light's intensity, move the Intensity slider or enter a value in the box.

Step Ten

To change the light's Falloff, select Light Falloff and enter values for the Inner and Outer limits. The Falloff affects the illuminated areas and the object shadows.

Step Eleven

You can set a specific light position and angle by selecting the Coordinates icon in the Properties panel. Values can be entered for X, Y and Z Position.

Step Twelve

Once you are finished with your adjustments, reposition the camera by click-dragging in the view box. Render the scene by choosing 3D > Render.

Lights Without Shadows

You may want to add multiple lights to your scene. It is possible in the Properties panel to activate shadows for just one or two of the lights.

Soften the Shadows

Another option in the Properties panel is Shadow Softness. The slider can be adjusted to soften or harden the shadow edges.
