what do you use for post?

 

i dont think you need an animated zdepth with focal point thingamajig for a pull focus shot, a normal one generated with teh main pass will do. (you use vray yes?)

 

make sure you have a full range from black to white between your 2 focus subjects and animate the focal point parameter. im using fusion and its pretty straighfoward, i assume its similiar in other post packages.

 

iv posted the options i have when using depth blur in fusion, sorry im not sure what else you could do (other than in vraycamera...and then if it doenst work properly you need to rerender again!!)

Hello all!

 

In after effects just import both the RGB pass and Z-depth pass to your timeline. Make sure your Z-depth layer is under your RGB layer.

 

Apply a Lens Blur effect to your RGB layer... go to Effect > Blur & Sharpen > Lens Blur.

 

In the controls for the blur effect go to "depth map layer" parameter, click and select the name for your z-depth layer.

 

Change the values in the "Blur Focal Distance" parameters to see how the image changes focus points based on the values. This is great for animating Depth of Field....

I hope it helps!

Combustion is probably easiest (even if you don't know it). Just render to a .rpf file format making sure that the coverage and zdepth channles are checked. Open it in Combustion and add a 3d depth of field operator. Then you just type in the near and far focal range in mm (or whatever units you're working in). This can be easily animated using a timeline just like in any other application. You should give it a go some day. Motion blur is a snap too!

this looks really interesting, i'm going to have to give fusion a serious look. cheers.

This is how I would approach it:

 

Put your camera in front of the teapots. Add a z-depth pass to your render elements. Make sure the Min/Max distances are approximate for your z-depth pass. Use a "tape helper" to get your min/max distances and see how far away they're from your camera. Render out the images, and follow the procedure on my previous post for after effects.
