After showing Andy the original pass of animation for this scene and mentioning I was having problems with the camera sway from side to side during the keyframes he said I should try using 'Camera and Aim' in maya as I can individually control the positioning and center of focus. I said sure, and was interested to see if it would make a difference in any way as I have not had much experience with the camera and aim. After testing it out, I was amazed to see the difference and superior control, it really helps and gives great control as both elements can be keyframed separately. I have found it so much more useful I think I will use just the cam and aim for any animated camera movement in the future.
I think the new camera movement has been animated better, and I tried to give enough time between zooming out of the sub and switching focus to the iceberg. The focus was the easing in and out, which I think I nailed..
