Background blur, also known as bokeh, refers to the aesthetic quality of the out-of-focus areas in a photograph. It is achieved by using a shallow depth of field, where the subject is in focus while the background is intentionally blurred. This technique helps to isolate the subject and create a sense of depth and visual interest in the image. Background blur is often used in portrait photography to draw attention to the subject and create a more visually appealing and professional-looking image. **

Within this section, there may be a specific option to toggle motion blur on or off. Alternatively, you can also try adjusting the graphics settings to lower the overall quality, as this may also reduce or eliminate the motion blur effect. If you are unable to find these options within the settings, you may need to consult the game or software's documentation or support resources for further guidance. **

The natural logarithm (ln) is used to calculate the growth rate. This formula helps to determine the rate at which a population is growing or declining over time. **
