How do you check what your FOCAL POINT is with a camera?
Hey there
Basically Ive got 5 different layers in a 3d space, all about 200 pixels apart on the z axis and i want to use a camera to pan and zoom into them, but i only want to have 1 of the layers in focus at any one point, so i guess it needs to have quite a short depth of field. ive kind of got it by changing the aperture etc, but how do i find out when each layer is exactly in focus, so i know when to stop it zooming in or out on the layer?
Any help on doing this kind of thing with a camera would be really helpful……
Thanks alot!

Change your View to top view.. and you’ll see your focal point move when you adjust it.
“kis” it

You can use an expression like this for the camera’s Focal Distance to make sure a (“target” in this case) is in the camera’s focal plane:
P = thisComp.layer(“target”).position;
dot(P – position,toWorldVec([0,0,1]))Dan

It seems that the info in this thread should have fixed an issue that I’m having, unfortunately it doesn’t.
Usually when I’m trying to focus on a 3D layer, I simply view it from above and adjust the focal distance until it’s even with the layer I want to be in focus. This has always worked for me in the past, but for some reason in this particular project, the layer is EXTREMELY blurry when I use this method and I can’t figure out why.
Any ideas on something I may be missing? Thanks in advance.
