I have a vertical image, so I want to rotated my camera to fit the composition, but I am running into a lot of issues. My first problem is, after rotating the camera vertically every time I press 0 the view port also rotates. I end up looking at my composition in this really weird horizontal angle. I don't want this, I want the camera to keep the vertical perspective, but rotating the view by 90 degrees. See my problem below.
My second problem is, I want the camera to cover the entire image, so I can accurately place models into the scene with respect to the composition. I thought about placing the camera using orthographic mode to cover the entire image, but the camera bounding box disappears. I am now sure how to do this.
Does anyone know how to solve these two issues?
