In this tutorial I am going to show you how to light up a Blender object not by using the default lamp but just by using a background image.
Start a new Blender project then switch it to Cycles Render and then go to the property panel and select the world tab. Under the Surface sub panel click on the Use Nodes button and then click on the button beside the color palette and select Environment Texture, next click on open and select an image as the background image for the scene!
Turn off the lamp by clicking on the eye icon once so we only light up the default cube with the background image.
Next under the Render tab Film sub panel checked the Transparent checkbox so the background image will not appear in the scene but still will light up the default cube.
Next select the default cube then go to the Material tab and click on the Use Nodes button. Select Magic Texture from the button beside the color palette.
Now click on the Render tab and render the scene.
As you can see the background image has replaced the lamp to light up the object’s scene.
