Euler is the name of the mathematician who originally developed the math behind all of this. So we have the axis order here. From that pulldown list choose the last one in the list z,x,z. And now when you do that you can see that mysteriously one of our axis has disappeared. We actually got into a Gimbal lock situation just by changing the axis order and now two of the axis are superimposed over one another. But I can fix that very quickly just by setting the y value to 90 degrees. Just type in a 90. And now we’re at a good place. We’ve set the axis order correctly. So let’s test it. So I’ll rotate around the z axis which is in this case the pan and the other two axis follow, that’s what I want to see. then I’ll rotate around the tilt axis, which is the red one or x axis .

So now I can rotate around the green axis or the y axis or the dutch tilt and the other two axis do not follow and this is exactly the situation I want to achieve. So I just reset these values x at zero y at 90 and z at zero and then I can proceed to frame up my shot in the usual way. so having set it up this way, it’s pretty bulletproof I’m not very likely to have any issues with animation. And the line of sight axis or that dutch tilt axis which is the y axis in this case has been de-prioritized so it won’t affect any of the other rotations. That’s how to set up the axis order for a free camera.
