In the next image, Motion Blur is enabled and Samples is set to the default value of 8.

Note: When using larger Shutter Angle values, it may be necessary to increase the Samples
value to eliminate unwanted artifacts.

In the above image, the Shutter Angle is set to the default of 360 degrees, which represents
1 frame. In the following image, Shutter Angle is set to 600 degrees.

The Reflections section of the Render Settings tab has one parameter:

Maximum Bounces:

When a reflective object is itself reflected in another object, the first

object can be seen in the reflection, potentially causing an endless repetition of reflections.
This parameter limits the number of “bounces” that can occur in a scene. The number of
allowed reflections is set per project.

About Bit Depth

When working with images, an increase in bits per pixel for those images means more
color information becomes available. A one-bit-per-pixel bitmap image is comprised of
purely black or white image pixels (no shades of gray).

A grayscale image comprises image pixels with 256 levels of gray. Each pixel requires
8 bits to represent the 256 shades of gray. Therefore, the bit depth of a grayscale image
is 8 (2

8

= 256).
