Put in your “tech-talk” pants, it’s time to speak sensor measurement.
Welcome to The Queue — your day by day distraction of curated video content material sourced from throughout the online. In the present day, we’re watching a video essay that appears on the variations between mild sensor sizes.
First issues first, I wish to guarantee these of you who discover all this technical stuff a bit daunting: as we speak’s video essay remains to be for you! A part of what makes video essays so enjoyable is that they make it simpler for people to strategy inaccessible subjects. Individually, I’m a visible learner. And seeing graphs and side-by-sides in movement makes a world of distinction.
So with that out of the best way, let’s cowl a number of fast introductory factors earlier than launching into as we speak’s essay:
What does a digicam’s “sensor” do?
Sensors (to not be confused with mild sensors) are also called the movie airplane, a sensor airplane indicator, or a focal airplane indicator. The time period refers back to the floor of the digicam the place the lens creates a centered picture. Focal distance isn’t measured from the entrance of the lens or the again of the lens however from the floor of the digicam sensor. All this to say: if you wish to precisely measure the focal distance of your lens, you could know the place to take that measurement from (a.ok.a. the movie airplane/sensor).
To sum up: cinematographers use movie airplane indicators to know the precise focal size between the digicam sensor and the topic. It’s an vital software in ensuring all the pieces seems to be proper.
Why are there completely different sizes of sensors?
As a result of there are completely different movement image codecs, from smartphones to tremendous 16mm to IMAX. Completely different codecs have completely different focal necessities.
How do completely different sensor sizes have an effect on the filmmaking course of? The visible look of a movie?
Effectively, I assume you’ll have to observe the video essay beneath to search out out… 🙂
