Why do smartphones have the LED close to the lens?
Wouldn't it be better to place the flash LED as far away from the lens as
possible to avoid red eyes? -- Alfred Molon ------------------------------ Olympus E-series DSLRs and micro 4/3 forum at http://tech.groups.yahoo.com/group/MyOlympus/ http://myolympus.org/ photo sharing site |

A point source, like a naked LED chip, causes extremely harsh shadows on contours. These shadows can't be seen if the camera and point of light are in the same place. A cellphone isn't large enough to avoid red-eye anyways. |

Well, the obvious reason is that the camera is one component in the phone, and fividing it requires extra wiring and less space for that huge battery. The other reason is that the user has to learn where the lens is physically to not cover it with their hand when holdig the phone, and if they had to also learn another spot where they can't hold their hand because that's where the flash is, well you're going to end up with tons of badly lit pictures. Contrary to when you're hold your hand over the lens - the screen can't give you any feedback if you're doing the same with the flash, whch is why it's logical to place it with the lens. -- Sandman[.net] |

Some camera apps may, but built in camera apps doesn't. Also, red eyes are generally only a problem when tip #2 can't be met - i.e. when you don't control the situation and just snap an in-the-moment picture. Tip #3 is just stupid, i.e. take pictures when red eye's aren't possible - i.e. take pictures of people when they're not up close and facing the camera. Well duh. Tip #4 is also irrelevant to phone photography since no phones comes with a telephoto lens, and the ones that provide zooming does it really poorly (i.e. never ever use digital zoom on any camera ever). The best way to deal with red eyes is in post. That said, I am one of those telling everyone never to use the built in flash ever, but on a phone that may be your only choice for dim lit situations. -- Sandman[.net] |
