The only issue with using tint is when objects aren't facing the camera. If y=
ou have a wall that is perpendicular to the camera going back I depth it wou=
ldn't show any depth via tint

I haven't had a chance to try the following but if you place a light at the c=
ams position and use the falloff to create the gradation I imagine you shoul=
d be able to get a more convincing depth matte. All your objects i course wo=
uld need to be set to white. No reflections etc erc. And also need to minimi=
ze any antialiasing since that is detrimental to a proper depth matte
