So first we'll create a camera, and then we'll look through it and we'll come over to Tags, Cinema 4D Tags, and add the Camera Calibrator. Now the camera calibrator needs an image, so we'll load one in. And then we'll move over to the calibrate tab and we can start to add some lines, grids, and things like that. And the goal is to get some solve data and the focal length. So we'll add a grid, and I'm going to position the points and as I do so, we get this zoomed up view of where our point is going to drop so we can line that up with the table here. Now if this bit's hard to see we could lower the brightness and then, position that point We just increase the brightness once again come back…
