- [Instructor] The size of the camera sensor is very important for applications such as camera matching in which you're matching a 3D rendering to an existing still photograph or live action video. It's also good to understand just generally how sensor size affects the field of view or cropping in the rendering. I've got a physical camera here. I'll select it. Go over to the modify panel. And the cropping in the viewport and rendering is controlled by the interaction between the sensor size and the lens length. Just like on a real camera in the real world. We've got a default focal length of 40 millimeters for the lens and a default sensor size of a 35 millimeter still slide photograph, or a full-frame DSLR. That combination of a DSLR full-frame and a focal length of 40 millimeters for the lens, is going to give us a particular field of view value. Here it's 48 degrees and change. If we change either the length of the lens or the size of the sensor, we'll get a different cropping in…
