I’m new to this YouTube channel, but they have some very interesting videos. This one explores the evolution in iPhone photography, from steady camera hardware/sensor changes to a focus on software, with the rise of computational photography.

Don’t be put off by all the fooling around in the video. There’s a lot of interesting stuff here. A few highlights, if your time is limited:

• At about 3:30: iPhone life with that original interface, before the App Store existed. Only one page.
• At about 4:27: All about “rolling shutter”
• And, at about 12:18: The core of this video, comparing the old and the new

I enjoyed the whole thing. Obviously, you’ll want to watch this in 4K for maximum effect.
