Architectural Visualization Post Processin (AVPP) Series #4

There are some certain things we need to know to facilitate an easy workflow between raw render and post processing. In this simple but very important tutorial by Luis Carlos Mendez, he emphasized some easy to follow steps, but often neglected during the rendering process. The first one is the importance of saving in "png" format and the second one is the importance of matching HDRI with background environment. To explain further here is step by step AVPP of Luis Carlos Mendez.

Step1: Saving the Raw render

Here is the raw render image. Be sure that you have a png file format. Be sure also that in the Vray channels you selected both Diffuse and Alpha Channel.

Step 2: Adjusting the exposure

Adjusting the exposure, in the image below minimal adjustment of levels, color balance and brightness and contrast were done. I should say pretty stratight forward Autos...

Step 3: Adding the Backgound.

It is very important to consider between the ambient light created by an HDRI (especially in night time tutorial) and the background image. You can download the HDRI i used HERE. Below is the background image that I will be using for this AVPP.

Background added to the background. In photoshop is easy, all you need to do is to put the Background image below the render file. This is where png file is handy (png file supports transparencies).
