Trivial example: Apple introduces a function that can dim the flash from slight glow to full power. Some person develops a photo app that takes more beautiful softer images of human faces making your product the preferred beauty (selfie) camera.
I just found out that with IR light freckles disappear

AN improvement to this idea. An item on reddit [link] says that with IR light melanin disappears, so having two different flash leds, one IR, would give the ability to make dots of freckles gone. |
|

That is the other idea: Have more than one flash LED, with different frequencies of light, not just IR, different visibles as well. |

I'm not so sure the softness issue is the brightness, but the
wavelength. That's a lot harder to do. But I see that you've
considered that as well. Surprising that they haven't done
something like this yet. |

My advice would be to actually try and patent this. |
|

I think mostly you'd want to go for colour, not brightness : make soft shots in a soft (ie: red/yellow heavy) light. |
|

One of the problems with this idea is that you really don't
want the flash directed at the camera, unless you are going
for a film-noir backlit effect. You really want the flash next
to, or even part of, the camera. |

Just how dim would the "flash" have to be to produce a "beauty shot" of [I
T] ? |

We estimate that turning it off altogether would give the best result ... |
