An artist must find the best way to place his scene in front of a camera, and pick the best framing to render your project. And a great reference to create a good framing for a scene comes from photography, like the rule of thirds. This is a way to use guides to place objects in key points on the image and make it more interesting. One of the new features of Blender 2.58 will help artists to use this composition rules. At the camera panel we have a new dropdown menu called Composition Guides, and there we can choose from several composition guides that will appear at the camera view.
How it works? To show you how to use these guides I made a quick video about this new feature.
thats cool feature thanks for showing
