How your phone camera works. It's a well written article but it seems odd to cover how a camera works and leave out Aperture because of the edge case of having a fixed aperture as in a smartphone. With a longer description of aperture and some picture examples of aperture controlling DoF and exposure this would have been a complete introduction to digital photography, now it's a complete introduction to fixed-aperture digital photography...
True, but title is really misleading, and from true photography point of view, smart phone cameras are edge case, on low quality end of spectrum.
Also, most people with smartphone will never care for more than point & click, so suggested slight enhancement of coverage would make much more sense (although it doesn't put in anything that isn't already written out there 1000x times).
Thanks for the feedback. The reason I picked this title is simply because "your camera" for most people will be their smartphone. A bit too catchy for people with a DSLR.
But as other people have noted: Most photos today are taken with smartphones. I touch upon aperture, and linked to Wikipedia for those interested in in-depth information.
