I'm using depth of field for my animation.
I created a second camera
Shift-A -> Camera (not a duplicate) and noticed it copied the f-stop keyframes from the first camera.
I made sure the second camera was active in both the "camera" tab and the "scene" tab before deleting keyframes. It's also active in the "properties" pane.
When I deleted the f-stop keyframes from the second camera, it also deleted the f-stop keyframes from the first camera.
Is f-stop global among all cameras, like a material is among objects? I think not. What am I doing wrong?
EDIT: It's also re-using camera one's target and is showing 2 users in the "camera" tab.
EDIT 2: I
Ctrl-Z'd all the way back to before the second camera creation, created another camera
Shift-A and it didn't happen this time. Weird.
