    Hi Guys,

    I’m looking for an easy way to focus on objects in space without using 3D-mode. Let’s say there are for objects and when I focus on object 1, I want object 2 to be blurry, 3 even more, 4 to be the blurriest.

    This I want to do in a logical way and a way that does give me the option to make things more blurry afterwards.

    I thought of making an expression like this:

    Object 1 BLUR: 10-thisComp.layer(“Object 2.”).effect(“Camera Lens Blur”)(“Blur Radius”)
    Object 2 BLUR: 10

    But it turned out that in this specific case, where I have a blurriness of 10 and only two different objects it works out alright. I’d like it to be a bit more interactive. Anyone an idea what would work, without me using the camera?

    I’d suggest using a linear() expression on each object pointed at a slider with an offset to each one such that, as the slider is at 1, object one is fully in focus and as it gets further from 1, object 1 gets blurrier and when the slider is at 2, object 2 is at its sharpest and gets blurrier as the number goes further…if that makes sense. 🙂
