The iPhone 5S' flash has two tints, cool and warm.

Please don’t turn this into a fanboy fight! Lets keep this discussion relevant to the LEDs that are used in the phone.

Thank being said,

Apple just introduced its iPhone 5S, which has dual LED flashes to illuminate subjects for its camera.

One is cool white and the other is warm, to accurately match the color balance of the room.

I’m not sure if the software controls the brightness of either one depending on the environment.

Here is is, from The Verge:

I guess the top is cool white and the bottom is warm, judging by their colors.

If you ask me, thats just marketing blabla. Thats what white balance is for..

But we've seen it with the Galaxy S4. There isnt much left to put into a smartphone, so the nonsense war starts. ;)

Wow, didn’t know that the GS4 and the Note 3 also had dual flashes.

I sense some lawsuits…

oh please. The N900 had a dual LED flash in 2009.

With dual tints? :smiley:

Its about time apple got a few lawsuits back…

No, the N900 flash had a nasty green hue, and a lens flare issue with the flash reflecting off the bezel of the camera cover. I know this because I own an N900 myself.

Dual flash tints do make sense though, as I’m guessing it’s 5600k (daylight) and CTO (~3400k). CTO matches perfectly with ambient incandescent lighting. 5600k matches perfectly with a bright sunny day, though I doubt the flash is powerful enough to be used as fill light. You really need a xenon burst for that like the old N95 has.

Whitebalance can only compensate for one tint, when there’s two tints in a photo both of them will shift accordingly. Whitebalance for incandescent light and fire your flash, and your subject will turn out blue.

Aside from the photographic applications the warm led should be more pleasant than cool white for flashlight use.
