Hi All,
I remember reading about the fact that the newborns either do not have
as fast reaction of the pupil to the bright light, as most humans do,
or their retina is too fragile, and that until some age (N weeks), a
photo flash (especially with repeated use) might cause some damage to
the retina. I cannot seem to find any "solid" source for that now, and in
particular, I don't remember how many weeks that lasts.
I've found a bunch of "anecdotal" evidences that are not serious
(e.g. "I was photographing my newborn son with a flash, and
his vision now, past 15 years, is fine."), but I cannot find
any published research on this topic.
(I did find a paper from 1982 saying that the newborns have central
part of the retine underdeveloped, and they have mostly pereipheral
vision. And I found a paper from 80s showing that after the 34th week
of gestation the pupil does change it size in response to [some] light.)
I was wondering if any of PDMLers either has a reference to the source
of information or knows a children's ophtalmologist with experience
about these question.
Igor
More "anecdotal" information I'm afraid, but my [limited] experience
with photographing new-born babies is they spend most of their time
asleep, so their eyes are closed.
I don't think the flash will harm them even if their eyes are open,
although it might upset them. I'd use bounced flash or a soft box to
diffuse the light so it wouldn't bother them as much.
