Motion Blur, Depth of Field, and Atmospheric Perspective Guide. Check out the full Citizen Video Tutorial here: cgcookie.com/concept/2013/11/2…

In this tutorial, 
Tim Von Rueden takes you through the basic understanding of the three visual illusion concepts. This tutorial is the direct result from being the number one requested tutorial from the third week of this month's November Citizen Tutorial Request Month. These results were featured from the poll on our Deviantart Page. Stay tuned for future polls in which we will once again ask, "What tutorial would you like to see?"

The three visual illusion concepts covered here are Motion Blur, Depth of Field, and Atmospheric Perspective. 

Motion Blur: This is the result of capturing a few frames in motion caught in a single image. A stable image should be one that is more crisp/sharp while the objects in motion should have a "doubling" effect which often looks like blur.

Depth of Field: This is the result of focusing of focusing on a particular distance on a subject matter. This makes the areas further and before the focused field appear blurry and has a tendency to add more of the "blur" effect the farther the distance. 

Atmospheric Perspective: This is the result of the atmosphere interference while viewing an image. This tends to happen mostly in environment art but it's when the atmosphere is causing the illusion that objects are "disappearing" the further away the are.

Duplicate the image, And motion blur?! THAT'S NOT A TOOL!

I figured out a good way, which is duplicate the image and offset it with the opacity down.

Very good examples, but the third example is not well understood.

In short, the particles in the air make distant objects less visible. If you look at the little rock formations in the background they're almost gone because you wouldn't be able to see it well with high atmospheric conditions. Does that make it a bit clearer?
sira's avatar
Yes, now I understand better. Thank you very much for the clarification :)

Can anybody tell me more about the third one, please? Or how to achieve something similar.

Looks like a great and practical effect.
Thanks.

I'm hoping to grab an environment artist to do the full tutorial on this subject matter, because i think it needs a more in-depth look at how to create this effect.
