Composition

[juand731]

Hello everyone I am doing some work on vray, I have gone thru the tutorials with the compositing, and understand very well how it works, im just wondering if someone can give me some information what type of modifiers do I do to the composite images in photoshop, for example zdepth do i give it a multply or screen? and for my ambient occulsion, shawdows, reflection, refraction? and in what order do i stack them in photoshop?

I Apperciate it alot if someone can help me out with this issue,

Thablanch, thanks for your reply, the thread was really confusing though with chaosgroup, does someone have any straight forward stuff with photoshop or fusion? I have seen all the links, and they dont really explain the post production part of it, http://area.autodesk.com/index.php/tutorials/tutorial_index/making_of_the_auditorium/ this tutorial here is very good but I was hoping someone could go more in depth how this layers are setup in photoshop, and in what order? what kinf of color correction, lens, or anything else do we add to them? As i have seen from many people in the field that post production is the most important part of the process to give your image more life. Well i hope someone can come thru, Thanks.

Kind of a tough question to answer... so much of post work depends on the scene itself, and your own personal aesthetic. Those two posts linked above will get you started from a technical end. From the creative end, just trust your eye, and post some results here for some feedback.

 

If you read through the Chaos Group thread, Chris Nichols' Combustion workflow gets translated into Photoshop vocabulary. As far as setting up the layers and their order, once you see the translation from Combustion nodes to Photoshop layers, the layer setup will make sense.

As mentioned before, since each scene is different you really just have to mess around with your render elements and the blending modes in PS. Best way to get a feel for the possibilities is to render a simple scene with all render elements active, bring into PS, and experiment with blending modes (Multiple, Screen, and Overlay esp.) as well as layer masks. Zdepth can be useful as a depth map when using the the Blur>Lens Blur filter, but you'll need to try some things on your own. If you come across any new compositing links, post 'em up...

AS for zdepth its really more of a mask of the scene based on depth. I use it mostly for depth of field.
