Tutorial: Creating a Reusable Light Box
For everybody who is new to Blender and product rendering Alex Telford released a small tutorial which in a very compressed format highlights a best practice approach for modeling a scene and setting up lights with Blender Internal.
As a renderer he uses Blender Internal, however with an adjustment of the area light energy settings, this tutorial can easily be used with Cycles as well. With Cycles however you should disable the Mask modifier when rendering because Cycles renders what you can see inside the 3D view meaning the hidden geometry will stay hidden also during render time.
