Course Preview - Learn Photoshop for Architectural Visualization: Using The Vray Zdepth Channel For Depth of Field and Fog Effects
January 28, 2015
I am continuing to work on my next professional architectural visualization course. Â This one will be, as promised, all about Photoshop for architectural visualization. Â It is important to learn Photoshop as a 3d artist, because post-processing is what can really set an image apart from the crowd. Â
Â
Throghout much of the course I will be discussing Vray render channels (elements), and showing how to leverage them properly in your scene to really enhance the raw 3d rendering. Â This particular sneak peak at my course covers the Vray Zdepth channel.
Â
Zdepth is a black and white map that contains depth information. Â Basically, white is close to the camera, and black is far away. Â So, there is a complete range of depth in your scene, depending on how far things are away from the camera point of view. Â This map can tell the computer how far things are away from you in relationship to other objects in the scene. Â With this information, some cool things are made possible. Â This video shows how to first, use the depth information to create depth of field blurring - just like a physical camera, and second, add atmospheric perspective to your rendering by adding fog / haze. Â Both of these things can be accomplished within the rendering as well, but doing it in post potentially saves a lot of render time, and also gives you much more control. Â
Â
Check out the video to see what I am talking about, and stay tuned for updates (and discounts) on the upcoming course.
