DOF: Control the depth of field effect in Photoshop or AE, using a depth map from Vray



Play Video in Full HD and with Custom Captions/Subtitles (CC)

Depth of field (DOF) is the distance between the nearest and the furthest objects that are in acceptably sharp focus in an image/3d render.

The depth of field can be calculated based on focal length, the distance to the subject, the acceptable circle of confusion size, and aperture.
At times, the depth of field can be chosen for technical or artistic purposes.
Limitations of depth of field can often be fixed with a variety of  techniques and/or equipment.

This short Video tutorial takes users through the quick process of adding and tweaking the dof in post production, using 3ds max and Photoshop.

Using  the dof (depth of field) directly in your 3d scene can at times be irreversible, when faced with a tight deadline. However, using a depth map (e.g. vrayzdepth, etc ) in post (Photoshop or After Effects) will provide you with the ultimate control to rectify any potential tweaks that might arise from last minute changes from a client.

Important Terminologies & Descriptions:

3d Rendering: Is the process of converting the three dimensional (3D) data seen in a 3d scene into 2D image/s (rasterized).
The rasterization process include, the rendering parameters, the rendering engine, lights, 3d models, textures, shaders, and other effects. 
3D renders can be a sequence of animated objects/effects/cameras, or a single frame with a still camera and object/s.
Some of the articles, Videos and Tutorials depicted here will take you through the process of rendering.

Architectural Rendering, or architectural illustration/Visualization, is the art/process of creating two-dimensional images or animations depicting the attributes of an architectural design, while using state of the art applications such as, Autocad, 3ds max, VRay, Cinema 4d, Blender, Maya, Corona, Photoshop, etc
Some of the articles, Videos and Tutorials depicted here will take you through the entire process.


Photorealistic Rendering: Is the Process or Art of making a typical Computer Generated Image/render (CGI) look indistinguishable from a real photo.
To achieve this, users often need to possess the skills and the"eye" to appreciate good photography, cameras, composition, lighting, shaders, materials, 3d modelling, rendering and have some post-production skills. 
Some of the articles, Videos and Tutorials depicted here will help you achieve truly photorealistic renderings. 


Post-Production: Is the process of creating effects or/and results after (post) the main process.
This terminology can be used to describe the results (post-production) of main processes such as 3d renderings  and/or filming a scene.
The post-production often occurs in applications such as Photoshop, After Effects, Nuke, etc.   
Some of the articles, Videos and Tutorials depicted here will take you through the process.


Textures: Is a term often used to describe photographed  2d images to be later used in a toggle of a shader or procedural map.
Textures can be used in the Diffuse toggle, Reflect, Glossy effects, Bump, Displacement, etc. 

Some of the articles, Videos and Tutorials depicted here will take you through the process of applying textures.

Materials: Is a term often used to describe maps, textures,procedural maps or shaders, depending on the context the term is being used.
Some of the articles, Videos and Tutorials depicted here will take you through the process of applying materials.


Procedural materials: Is a term often used to describe maps with editable/proprietary parameters/functions.
Some of the articles, Videos and Tutorials depicted here will take you through the process of applying procedural materials.


Shaders: Is a term often used to describe complex materials with functions and procedural maps created for a specific purpose.
Some of the articles, Videos and Tutorials depicted here will take you through the process of applying shaders.

V-Ray: Is a rendering engine that uses global illumination algorithms, including path tracing, photon mapping, irradiance maps and directly computed global illumination.
Furthermore, it is used as a commercial plug-in for third-party 3D computer graphics software applications such as 3ds max, Maya, Houdini, Blender, Nuke, etc,  for visualizations and computer graphics in industries such as media, entertainment, film and video game production, industrial design, product design and architecture.

3ds Max: Autodesk 3ds Max, formerly 3D Studio and 3D Studio Max, is a professional 3D computer graphics program designed to create 3D animations, models, games and images.
In addition, it has modelling, animation and movie effects capabilities, frequently used by video game developers, TV commercial studios and architectural visualization studios.
3ds Max also features shaders, dynamic simulations, particle systems, plug-ins, and much more, with its own scripting language.

Adobe Photoshop: Photoshop is a powerful raster based graphics program produced by the Adobe Corporation. 
It is widely used for a variety of photo/image editing purposes worldwide. The program has a huge number of filters, functions, plug-ins, scripts, etc.
In addition, there is a huge online support for this software, and countless online sites with tips and tutorials.
Finally, there are readily available books, online/college courses, and its full documentation at Adobe.com

A 3d Visualiser works within the realm of 3d visualization, a sector of the Computer Graphics Industry (or CGI) that is primarily concerned with the visual presentation of design concepts and ideas. And a company within the 3d visualisation sector offers to its customers (among many things) 3d Visualization Services.
