Nic H Posted January 6, 2009 Share Posted January 6, 2009 do it in post with a zdepth pass Link to comment Share on other sites More sharing options...
Dave Buckley Posted January 6, 2009 Author Share Posted January 6, 2009 any chance you could elaborate further Link to comment Share on other sites More sharing options...
mattclinch Posted January 6, 2009 Share Posted January 6, 2009 you need a cricket bat for a pull shot...... i'll get my coat... animate a zdepth pass that travels with the focal point of the camera and then use this to add the focus in post?

Dave Buckley Posted January 6, 2009 Author Share Posted January 6, 2009 probably need a hat and scarf too, its cold out cheers for the response, i still don't think i'm too sure what your talking about but will have a play and see what i come up with Link to comment Share on other sites More sharing options...
Nic H Posted January 6, 2009 Share Posted January 6, 2009 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!!)

Dave Buckley Posted January 6, 2009 Author Share Posted January 6, 2009 nice work nicnic, pictures paint a thousand words i'm using max, vray and i guess after effects is all i have access too. i have acess to combustion but don't know how to use it so not gonna attempt to learn this minute Link to comment Share on other sites More sharing options...
Cocytus09 Posted January 6, 2009 Share Posted January 6, 2009 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!

Macer Posted January 6, 2009 Share Posted January 6, 2009 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! Link to comment Share on other sites More sharing options...

Dave Buckley Posted January 7, 2009 Author Share Posted January 7, 2009 right guys where would my camera go on here in order to start with back one in focus and then gradually go out of focus to let the one in the foreground appear in focus anyone fancy a little bit of microsoft paint action Link to comment Share on other sites More sharing options...
Nic H Posted January 7, 2009 Share Posted January 7, 2009 put your camera behind the bottom teapot in the middle so that it is in view off to your left? Link to comment Share on other sites More sharing options...
Dave Buckley Posted January 7, 2009 Author Share Posted January 7, 2009 and the target??? Link to comment Share on other sites More sharing options...
Nic H Posted January 7, 2009 Share Posted January 7, 2009 sorry i meant right, and target straight ahead? do a test quickest way to test! Link to comment Share on other sites More sharing options...
Cocytus09 Posted January 7, 2009 Share Posted January 7, 2009 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. Link to comment Share on other sites More sharing options...
