Note: To aid the explanation of this issue, I used the dimensions roll, pitch and yaw which are usually used to describe the rotation of an aircraft.
I encountered a weird behavior of the 3D camera: When it is in "normal" (0°) rotation, all axes work as expected with the X-axis controlling the pitch, the Y-axis controlling yaw and the Z-axis controlling roll. But when the camera is rotated -90° along the Y-axis (for example to view an object from it's right side) both the X- and the Z-axes control the roll and the Y-axis controls the yaw.
How can I control the camera's pitch when rotated as described/shown?
I know that there are the Orientation controls, but when trying to move the camera around an object these are rather restrictive for animations since they can only be adjusted in the positive dimension from 0-360°, making some camera moves impossible to realize.
I'm not sure if this is a bug or whether I'm just not seeing a way to adjust the camera as described.
