Perhaps some sort of Bluetooth signal which boosts the level of yet-to-be-developed for constant lights? I’m sure folks are working on it, probably none more than DiveVolk—they are already selling a kit using BT to turn the housed phone into a monitor for a big rig with no wired connection, and marketing their own lights, and both Backscatter and Retra are selling hybrid video/flash units.Macro lenses are not an issue, but strobe triggering is impossible because modern phones lack a mechanical shutter necessary to sync with a strobe.
