Many people already asked me how can they achieved such render in maxwell. Actually it's not that complicated and most of the time it doesn't request any postwork. First and maybe the most important component is the floor material. Most of the time after explaining the technics, user always comeback to me and ask me why they can't get the same floor as mine. Theirs was always looking grey but not white. So to avoid waste of time and long test, here is the material for the floor : http://www.divshare.com/download/2401974-b44
Then the other component is the environment. Having a white environment is not necessary true in that case. I fund that the most important is to have a light burning the background behind the object you are shooting. To make it easier, here is what i' m using as environment : http://www.divshare.com/download/2402030-cfc
. It's a homemade LDR. The quality is not really great, but it can give good result. One thing is that you have to put the intensity of the environment to 2. Than set the the ISO to 400, the shutter to 4 and the f-stop to 22. These setting should be correct for a product shoot (like a coffee maker). Another important thing is to position the LDR in the good way. The black part should be behind the camera.
I have used this technics during a long time, so if i remember well, all this component should give you the right lighing setup. And don't worry about the wash out, if all your material are well calibrated, everything should looks good.
