Camera Settings Overview

To access the camera settings:

Select the camera in your scene.
Open the properties panel by clicking the camera icon in the Properties Editor.

Here are the main camera settings you can modify:

Lens: Choose between different lens types, such as Perspective or Orthographic, each impacting how your scene appears.
Focal Length: This setting, measured in millimeters, defines the camera’s field of view. A lower number provides a wider view, while a higher number focuses on specific details.
Sensor Size: Adjust the sensor size to mimic different camera types and affect depth of field.

Choosing the Right Lens Type

The lens type you select can significantly impact your scene’s aesthetics. Let’s discuss the two primary lens types in Blender:

Perspective: This is the standard lens type for most applications. It produces a natural viewing experience, with depth and perspective distortion that mimics how the human eye perceives the world.
Orthographic: This lens type eliminates perspective distortion, making objects appear the same size regardless of distance from the camera. It’s often used for architectural visualizations or technical illustrations.

Adjusting Focal Length And Sensor Size

The focal length and sensor size work together to dictate the camera’s field of view and depth of field:

Focal Length: A common range is 18mm to 200mm. Experimenting within this range can help you find the perfect balance for your scene. For example, a low focal length (e.g., 18mm) is suitable for wide shots, while a higher focal length (e.g., 85mm) focuses on the details.
Sensor Size: Adjusting this setting allows you to emulate various camera sizes. A full-frame sensor will show more depth compared to a cropped sensor.

Utilizing Depth Of Field (DoF)

Depth of Field (DoF) is a powerful visual effect employed in photography and cinematography to guide the viewer’s focus. It helps to emphasize the subject while softening the background.

Enabling Depth Of Field In Blender
