I find that last line perfectly justified. OP’s post was incredibly dismissive and incorrect but was written as if it was from an expert. It’s textbook misinformation as far as I am concerned.

The trick to getting the best out of camera phones is to shore up their weaknesses with external devices. Cell phone cameras are multiple stops slower than "real" cameras (i.e. they take in 1/4 to 1/8th as much light). So you add light to the scene to shore up that weakness. Most of these pictures were probably lit very carefully with high quality lights, or else were taken in bright daylight, and the phone was proba…

All Macro photography requires extra light, it's not just anything to do specific to cell phones. That's why there are so many flash rigs designed for this. Also, the iPhone 13 camera has ridiculously fast lenses[0]: Pro 12MP camera system: Telephoto, Wide, and Ultra Wide cameras Telephoto: ƒ/2.8 aperture Wide: ƒ/1.5 aperture Ultra Wide: ƒ/1.8 aperture and 120° field of view If you search for lenses for "real" camera…

> If you search for lenses for "real" cameras with those apertures and focal lengths, you'll find 4 digit price tags for each one. The aperture is relative to the diameter of the first lens element. So you can’t just compare these values directly.

Sure you can. The f-stop is the ratio of focal length to aperture diameter. A aperture of f/4 means, the aperture is one fourth of the focal length. At the same f-stop, you get the same light density on the sensor surface. The catch is: a phone has a much smaller sensor, so at the same f-stop, across the whole sensor less light is gathered and consequently, you have a weaker signal.
