visible light - How can opaque black object occur?


I know the fact that a material appeared as black when all wavelength photons were absorbed. I also know that opaque object is the result of reflection and scattering of light wave. Is it right? However, how can I explain about opaque black object? If all waves are absorbed, is there still available light at the surface of the material to reflect or to scatter? If there still light to reflect and to scatter, what is ratio of light in absorption and reflection/scattering? Is there really black object exist? Obviously, I have very limited understanding of physics.
