## Pixar in a Box

### Course: Pixar in a Box>Unit 6

Lesson 2: Mathematics of depth of field

# Algebra of focus

## Want to join the conversation?

• i dont get any of this
• Does this equation work for concave lenses or just convex lenses
• since when did computer science turn into math?
• Are we doing math or pixar in a box
• In the next practice "Circle of confusion calculation" at the last question there is a error. Because in the problem says "the aperture diameter is 20 mm", so DE is equal to 10 mm in this case. But this problem takes a radius value of 20 mm...
• i would like to take this time thank are sponsor of the day jgftthrhjkooiunhbvgdhfthtjynjj,kijghggfghjljivdfghjklkjhgfd
