How to Add Lights to a 3D Scene in Photoshop
Within Photoshop you can add either Infinite, Spot or Point lights. Infinite lights are similar to the way that the sun illuminates the outdoors. The rays travel in a straight line and create shadows with similar characteristics.
Spot lights illuminate in one direction in a cone pattern. Point lights radiate in all directions from a single point. A Point light is similar to an uncovered light bulb in the middle of the room.
In Photoshop open a new blank document (File > New). Set the image size to 1,024 pixels by 1,024 pixels.
Add a new layer to the Layers panel by clicking the Create a New Layer icon.
Choose 3D > New Mesh from Layer > Mesh Preset > Sphere. The object is added to the blank layer and it becomes a 3D layer.
In the 3D panel, click Infinite light to select the light. The light was added to the scene by default.
Click and drag the small sphere on the light controller to reposition the light. Watch the light effect on the object and the shadow cast by the object.
To soften the shadow you can adjust the Softness slider in the Properties panel.
The light's color is changed by clicking the Color rectangle in the Properties panel.
To change the light's intensity, move the Intensity slider or enter a value in the box.
You can set a specific light angle for an Infinite light by selecting the Coordinates icon in the Properties panel. Values can be entered for light Angle.
To add another light, click the Lights icon in the 3D panel, then click the Add a New Light icon and choose New Spot Light. The light was added based on the current view.
Spot lights can be repositioned by clicking the light and adjusting the arrow and rotation icons.
Once you are finished with your adjustments, add a texture to your object and click the Render icon to render your image.
