Lesson 1: How virtual cameras work

Depth of field

In this video we'll explore why regions in our scenes can go "out of focus." Lenses focus light rays for sharp images. When objects are close, light rays aren't parallel, causing out-of-focus images called circles of confusion. Depth of field is the in-focus area, controlled by lens choice and aperture. Small aperture (large f Stop) creates deep depth of field, while large aperture (small f Stop) creates shallow depth of field.

the emotions Joy ,Anger , Sadness,Fear,Disgust.and bing bong (bing bong is not an emotion) are inside Riley's head
• What is the meaning of focus at infinity? I observed that when focus slider is set to INFINITY, pizza is blurred. How this can be explained mathematically?
• Focus at infinity means that objects infinitely far away will be in focus. In other words, light that's parallel will be focused. That's why objects close up, such as the pizza will not be in focus.
• Why cant we have focus from far places
• is it just me or is joy a control freak?

I mean in the movie, she only allows happy memories
• At what causes the rays to fan out?
Is it because we are focusing on one part of the whole image?
If the whole scene is in focus, will all the rays be parallel?
What do they mean hitting the lens at an angle?
• how do I become an animater
