This is inspired by Daseva's "Red Nose
Removal". (OK, OK, it's an inferior echo
of
Daseva's "Red Nose Removal". We all
have
dry patches.)
A camera flash operates in something
like
a squinth of a second. The camera
shutter
itself operates in anything from a 30th to
a 1000th
of second, depending on
conditions and settings.
Nevertheless, I always ALways ALWAYS
(ie,
often) manage to blink at exactly the
instant when the flash flashes or the
shutter shuts.
Being photographed in mid-blink is not
flattering. Your face lacks the calm
repose
of sleep, and the closed eyes set in an
otherwise awake visage merely make you
look somewhat retarded.
Since red-eye (and now red-nose)
removal is straightforward using
software,
why can't we have shut-eye removal? It
should not be difficult for the software to
recognise a human face, and to
determine
that the two mainly-white shapes are
missing; it should also be possible for it
to identify the shallow U-curve of the
eyelashes on the closed eyelids.
Once the eyelash-curve has been parsed,
it simply needs mirroring about a line
from one end to the other, to create a
pinched ellipse which will be a
reasonable
approximation of the subject's eye
shape.
Simply fill this ellipse with white (and an
iris of course - colour selectable) and the
problem is solved.

Not all of us. You can get ointment for it now. |

Will not this idea discriminate against those with but a single eye in the centre of their forehead ? |

SImpler solution -supply each camera with a tube of cyanoacrillate adhesive for gluing eyelids open, or perhaps a small staple gun ....... [+] |

Right on! Glad to spark a (tiny) flame ;) everybody say pastryy!! <flash!> <casually shuts eyes> + |

//Gonna make it hard to take a photo of
people with their eyes shut.// |

Why not prevent the problem instead of fixing it? |
|

Human eyeblinks take about 0.1 second (100 ms), and are frequently triggered by the "pre-flash" exposure determination light from the (modern)flash. Simply time the imaging flash to occcur more than ~150ms after the "pre-flash," guaranteeing open eyes. |

Similar auditory pre-shutter sounds could work for shutter-caused blinks. |

When I'm taking group photos, particularly of children, I just take several photos and Photoshop together a composite where everyone is not looking silly. Group photos are a particular problem. If an individual is looking non-photogenic a fraction of the time p, then the probability of a photo of n people having everyone in it looking OK is (1-p)^n. So, if you take a lot of photos (m) of a group and you want a greater than 50% probability of taking at least 1 good photo, you want the probability of at least one person looking bad in every photo to be less than 50%, or
(1-(1-p)^n)^m < 0.5
Putting numbers in, if your group size (n) is 10 people and each person looks not-OK 30% of the time (a generous measure for children), then m, the number of photos you have to take before getting a greater than 50% chance of a shot with everyone looking OK is 25. This doesn't allow for your subjects becoming bored, which is why it's easier to just take half a dozen shots and Photoshop together a composite. |
