| The only issue with using tint is when objects aren't facing the camera. If you have a wall that is perpendicular to the camera going back I depth it wouldn't show any depth via tint I haven't had a chance to try the following but if you place a light at the cams position and use the falloff to create the gradation I imagine you should be able to get a more convincing depth matte. All your objects i course would need to be set to white. No reflections etc erc. And also need to minimize any antialiasing since that is detrimental to a proper depth matte On Sep 11, 2012, at 8:49 PM, "Chris Zwar" <chris@chriszwar.com> wrote: > Yeah, just use an expression with the fill effect, set the colour to a value based on the distance from the camera.

You set the fog colour for both black and white colours, then adjust the 'blend with original' value based on the distance from camera. > > I'm actually working on a tutorial called "think like a compositor" which shows how you can approach motion graphics projects in the same way a 3D artist would approach a project in a 3D program, to give you more flexibility in the final 'look' in After Effects. I demonstrate how to create simple z-depth maps inside After Effects.
