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?

    it's usually one subassembly and red-eye is easy to fix anyway.

    The best idea is to place the phone as far as possible of the camera, to
    avoid being disturbed during the shoot. Seriously, led lights are not
    the cause of red eyes ![/QUOTE]

    they are when they're the flash.

  4. 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.

    We're talking about phone cameras here, who don't have a "red-eye
    reduction" mode (tip #1), or at least most doesn't. iPhone doesn't have it,
    and my Android (Samsung Note II) doesn't either. 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.

    Your comments are irrelevant to my statement.

    Another well reasoned point.

    What do you expect? You posted nothing to be reasoned with. You made an
    incorrect statement and I let you know it. My entire post above that was in
    response to your earlier - also not well reasoned point - was very
    reasonable and correct. It was also photography related and on topic for
    the discussion. It contained no comments about you or your knowledge about
    flashes or phone photography, it contained no ad hominem's, no personal
    attacks, only reasonable discussion about the veracity of the information
    you linked to.

    Your response? Not so much.

    Typically, you snipped the context of my statement. However, please tell
    us the manner in which my statement is "incorrect"

    the reference is still there. do you not know how usenet works?
    it's a smartphone, not an slr with removable flash and many
    configurable settings. because of that, your link does not apply.

    redeye is trivial to fix in post. why even worry about it.

    No I didn't.
    Your statement is still quoted above.

    "Your comments are irrelevant to my statement"

    That is an incorrect statement, so I responded with a simple "No" to that
    one, given the fact that my post - to which you responded - was very
    relevant to the information in the link you posted.

    It's very ironic that you, of all people, tried to come back with a
    sarcastic "Another well reasoned point" to my "No" while failing to
    recognize that the lengthy response I wrote to the information in the link
    you posted actually *was* well reasoned, on topic and in spite of your
    denial - quite relevant. That is one up on you - who have yet to post a
    "well reasoned point" in this thread yet.

    That depends. Nowadays the standard smartphone size is 5" (or even larger).
