Here’s a dissection video for those of you who like photography better than biology. It’s a Khan Academy lesson that offers a glimpse into how digital cameras work on the inside. The camera being dissected is a Vivitar V25, a 2.1 megapixel camera that you can pick up for around $18 from places like Walmart. Although it’s basically the digital equivalent of a disposable camera, the camera still shares some things in common with higher-end digital cameras. You might be able to learn an interesting thing or two about how your own camera works.
After shooting the video above, the Khan Academy instructor needed to buy another copy of the camera. When he opened the new one up, he was surprised to find that it was a different revision/design of the same digital camera model. He then created a Part 2 of this dissection series comparing and contrasting the two revisions to see what Vivitar changed.
