Depth Of Field

[ZFact]

Hi all;

I am currently working on a housing development.... I want to

focus in on the foreground house with the houses in the

background out of focus.

 

I hav'nt really used depth of field much before and i am looking

for any advice on the subject.

 

thanks in advance

I have recently found blurring a layer in photoshop, and using a Z depth render pass as a mask for the layer works quite well, and cuts down render times, Not sure with C4D but am guessing it can render Zdepth elements.

 

Good Luck

Do you mean rendering out the scene as normal

and creating a duplicate layer in photoshop and bluring

one of the layers as the background then cut in the

foreground as the in focus layer?

Yup...C4D does it just fine. Turn on the depth layer in the multi-pass options.

Frosty, how does C4D's DOF features cope with glazing? in previous versions of Cinema the DOF would completely ignore glass. pain in the ass when your building is constructed entirely of it.

Turn on the depth layer in the multi-pass options.

 

 

When I turn on the depth layer do you need to check

depth of field in post effects.

 

When I turn on the depth layer it does not appear to

be there when opened in photoshop!

Thats because its not a layer. Its a channel. Once in PS..Select>>Load Selection>>Depth

Short coming I'm afraid. C4D views transparent/translucent surfaces as opaque with the depth channel. It doesnt work with alphas either. So any trees or people mapped to planes will appear as large rectangles rather than cut-outs.

 

To me this is one of the larger problems with Cinema. Keep in mind this is not restricted to using the depth channel in multi-layered output. This will affect rendered scene DOF as well.

when I render a multi-pass w/ depth checked I get a pshop file with a depth channel, but it's all black!

 

Are there any other settings that need to be checked?

 

Where in the manual is this discussed? I don't see it in the 9.0 manual, was it added in 9.5?

You have to set depth of field...front and/or back on the camera
