How does a smartphone Camera work? The science behind digital cameras.


Teddy Tablante writes:

Cameras are everywhere! There are probably 2 or even 3 cameras in your pocket right now. But how do they work and how can they take incredibly detailed pictures? This video will go into the fundamental science behind digital cameras. It explores how eyes work, the system of a smartphone camera, how photodiodes function, eye-based color theory, and frequency sensitivity.

The animation was done entirely using 6 main scenes in Blender. The camera was dissected from a 16Megapixel camera and then scanned and modeled. If you have any questions or comments, please feel free to share!

I am an engineer that wants to get others excited about engineering as well. I worked 8 years as an electrical and mechanical engineer on subsystems in machines that make microchips, specifically on Ion Implanters. I want to inspire others to get into engineering, so I decided to learn Blender. Eventually, I left my engineering job so I could make high-quality educational engineering videos for YouTube. My hobbies are: cooking, inner tube water polo, frisbee, and lindy hop dancing.


  1. This was a really great video. One of the best complete productions I have seen using blender.

    The only problem I had with it was the soup bowl scene. It was very weak compared to the rest of the visuals. I would have cut that scene out or redone the fluid simulation completely. It did not match the production quality of the rest of the visuals. In short, your soup is weak.

    I have seen a lot of blender videos over the years. Most of them are proof of concept shots dealing with a few technical aspects of what can be done with blender. This was a complete educational video that just happened to be done in blender. Very well done! I look forward to more learning.

    • Thanks Talmore!
      I'm glad that you enjoyed the video. I think Blender is a great space for doing educational videos- especially regarding complex systems with a lot of details and physics animations.

      Yup- my soup is truly weak. It was my first video, as well as my first attempt at doing animated fluid simulation. I spent a few days on the soup, and at times got some results that were a little better, for example, I tried to use a volumetric shader but in the end I was limited by render times. Hopefully, my next fluid simulation animation will be better, especially with the eevee renderer.
