Admittedly, those are not standard settings for any useful render. The goal here is to isolate one algorithm in order to understand its behaviour. Understanding an algorithm can shed light on its strengths and weaknesses and allows us to draw interesting conclusions for the more general case. |

Notes
Arnold — For light samples, Arnold uses effective sample counts that are proportional – within a constant – to the square of the user specified value. As we will see, this makes sense from a UI standpoint since the variance follows the inverse of the same rule in the case of Arnold. This makes the light samples slider linear in term of perceived noise. In the Arnold tables below, we will specify the effective samples per pixel along with the user samples. Those effective samples are gathered from Arnold's diagnostics files.
