If you are starting this tutorial here, you will need the result of the previous section.

Now let's look at the lighting.

Top Key Light

The main lighting direction is going to be coming from the top and slightly to the front. This will throw the shadow slightly behind and place a large highlight on the top of the pen. It will also light up the back and floor of the curtain thereby providing a gray reflection.

 

 

 

Front Fill Light

 

 

 

The background is still quite dark but we will address that in the next section.

Ground Light

Let's add another light to lighten the background. Duplicate the top light and set the Quad Size height to 40.

 

 

 

The background is purely diffuse, it has no specular component. The pen is purely specular and has no diffuse. This allows us to remove the specular contribution of the new light so it doesn't affect the pen.

 

 

Render Settings

There isn't a lot of noise in the image but you could increase the Glossy and Diffuse Samples and the Light Samples on the main light to have a cleaner render.

The one setting that does need to increase is the Glossy Depth. This is the number of times a glossy ray bounces. The lack of bounces is visible at the catch of the pen, where the glossy reflection is black.

Scene Analysis

It is worth looking at the AOVs to understand how the contribution of the lights and the environment effect the look of the pen.

The direct_diffuse and indirect_diffuse AOVs show only the background.

 

The direct_specular AOV shows the direct lighting of the main light as a large white highlight) and the fill light as the smaller gray highlight.

 

The indirect_specular AOV shows the indirect lighting after it has reflected back from the studio.

 

 Looking at the studio setup from the side we can see how it reflects in the pen's cylindrical shape.
