Cycles: glossy material is too dark I am new in Cycles render engine and node edit, now I want to try a simple scene with a bright steel.Here is my scene: The plane behind camera has the same angel as the camera because the cube is specular reflection to light.The strength of it is set to 1.600. However, it do not make any affect at all.


As you can see in the second screenshot, I want the render result(Bottom left) is as bright as the one in Preview(right, although i do not think the preview is bright enough, think of the steal, it should be more closer to silver). And the texture of the steal don't have any affect is a mystery for me as well(I want some scratches on the cube just like an anpolished steal in the real world), do I make a mistake in the node editor?
I have found my own way to solve my problem, I do not know if it is the best way.

Here is the result:
