Continuity Camera with your iPhone and Mac is just insane.

Was skeptical when they announced it but the picture honestly looks better than my DSLR webcam set up (which is so extra), and the latency is so low. 

Studio light, center stage and portrait mode are surprisingly actually useful and are excellently tuned.

All of that without a single user side configuration. 

Yesterday, I just clicked "Start Video" on my mac mini while on Zoom and within a second, I was streaming my phone's camera. The call went on for 2hrs and there was no single glitch. Amazing how well it worked.
