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.
Lighting a scene realistically is one of the most challenging aspects of producing photorealistic renderings.
Choose the Instance copy method, and use similar parameters to the ones covered earlier.
It's also common to tweak with the "Bitmap" "Offset" coordinate values in "V" and/or "U" to help target specific areas of the bitmap.
Note: When implementing the above mentioned technique using the VRay mesh light, the default "Sampling" "Subdivs" value of 8 may yield inaccurate/unrealistic shadows. To correct this, simply increase the "Subdivs" to 64.
While this value will produce realistic/accurate shadows, it will NOT increase the rendering times due to the "Store with Irradiance map" function being enabled.
Furthermore, when sending the final render, the "Indirect Illumination" "Irradiance map " values need to be set to "Medium" or "High".
Note: If the bitmap colours emitted by the sphere light are not prominent enough in the scene, simply use the "Color Correction" procedural map on top of the main bitmap; and increase its "Saturation" value until satisfied.
To apply it, simply open the "Material/Map browser" dialog and choose it from its list. This topic was covered in this post HERE.
Alternatively, increase the saturation in Photoshop and re-save the main bitmap.
To emulate the Payless self-illuminated display screen on the right hand side; I have simply created an object with a Payless self-illuminated bitmap assigned to the object, and placed a rectangular light in front of it to emit rays of the same image using the techniques covered earlier.
I hope you have found this article interesting!

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.
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 takes place in applications such as Photoshop, After Effects, Nuke, etc.
Some of the articles, Videos and Tutorials depicted here will take you through the process.
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 this amazing 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.
Studio Lights: They are fundamental in the process of creating appealing images/renders.
Lighting determines not only the brightness and darkness, but also the tone, mood and the atmosphere of a scene.
Hence the importance to control and manipulate the lights accordingly, in order to fully capture the textures and the vibrancy of your objects.
By distributing the shadows and the highlights accurately, you can achieve truly appealing images/renders.
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
