"Astronomers have pinpointed the moment Ansel Adams clicked the shutter
on his famous photograph, Autumn Moon, the High Sierra from Glacier
Point. It was taken on 15 September 1948, at 1903 precisely.

Don Olson, at Texas State University, San Marcos, US, and colleagues
used a combination of lunar tables, maps, weather records and
planetarium software to establish the moment, which had been in doubt.

Although Adams was meticulous about recording the technical details of
his shots, film types, lens settings, exposure speeds and so on, he was
terrible at recording times and places. Some commentators had thought
the shot dated from 1944."

Amazing what they can do. Did you see the links at the bottom of the article
about the determination of the first "Marathon" and Van Gogh's "White House

Yeah, a friend knocked on my door right after I had just finished my
shower today, and then walked away without waiting long enough for me
to answer, so I ran after him the few hundred yards I could see him in
the distance. Running in warm weather is uncomfortable!

So I spent part of the afternoon thinking about Pheidippides running to
Sparta and then another 42Kms to Athens in the mideastern summer of
Greece. Poor guy, at least he's not forgotten. I kept wondering why
they didn't send someone on a horse.

Oh god. The place will be crawling with every Ansel Adams wannabee and

Not only that, but getting busted for streaking down your street naked must

I have convinced myself that Van Gogh was myopic, in the ballpark of
-4.5 diopters. I cannot believe anything other than, he was painting
textures as he saw them. Obviously he was using an impressionistic
style as well, but I believe he was applying an impressionistic style
to something else, a *realistic* style where he was painting the world
as he saw it. Fuzzy, in a well defined way. Rings around night sky
objects. That sort of thing.

When I look at Van Gogh's work before he was exposed to impressionism,
I see this phenomenon in his realistic style as well.

Van Gogh was born in 1853, and died in 1890, so he did have access to
eyeglasses, which were invented over 100 years before. Also, when he looked
at his canvas, he saw it with the same eyes he did when he looked at his
subject, so we can presume that he painted what he saw, as he wanted it to
look.

People even today resist wearing eyeglasses/contacts, and even resist
getting eye exams.

I can only theorize that the problem was even worse in the last half of
the 19th century.

I, myself am Myopic to the point that my vision, without corrective
lenses, shows me a night sky that looks very much like a Van Gogh
painting.(about -4 diopter @ infinity - 0 + 0 @ 6 FT (thus graduated
lenses are a "miracle" for me)).

Since Myopia (at least in my case) doesnt make my near vision distorted,
a painting (or photo) of the night sky on an easle wouldnt look the same
as the night sky does (because of the distance).

Thoght I wont go so far as to agree with the theory that Van Goghs
vision problem resulted in his style of painting, I cant argue against
it either, because it isnt likely he would have known he needed glasses
(there wasnt any requirement for him to have an eye exam) so he might
have assumed his vision was the same as the rest of the world
population.

You may be right. There is no way we can know today.....I am reminded of an
art teacher I had once who said that Goya painted long skinny figures
because he was astigmatic. I knew immediately that that couldn't be correct,
because when he looked at his canvas, he would also see tall skinny figures,
so if he made his paintings look like what he saw, they would also look like
what everyone else saw. But, you know, I couldn't convince the teacher of
this, so, in order to avoid a battle that I couldn't possibly win (I needed
the grade) I let it drop.

Here I have to agree with you.

Astigmatic aberation in vision is usually a "constant" AFAIK and only
changes according to Pupil size (light levels) and can be lessened
(somewhat) by squinting. The aberation is not affected (much) by
distance, so the nearby canvas would appear, more or less, the same as
the distant subject given the same distance.

Yes. I have gotten into these kinds of arguments with the "experts" in a
field before. One of my favorites is the contention that Stonehenge was
constructed by ancient astronomers, because if you sight along the edges of
the stones today, you will see certain stars where they would have been in
the middle ages. I say, "Horsepuckey! All of these stones have settled into
the wet British soil over the years, so you can't possible know where they
were when the thing was built." But I still see learned articles that claim
it was an astronomical structure......

I've also heard that Giotto was supposed to have severe
astigmatism, due to the rather willowy figures he painted. I've not
doped out why this wasn't corrected by reversal when he painted. The
figures on canvas, if normally-proportioned (to a person with normal
sight0, would have apeared the same to him as his subjects.

However, I still can't map this line of reasoning as well to a
person wose vision is simply blurred.

Of course. The same reasoning applies to the argument that all men see red
as blue. (compared to all women) There would be no way to tell, (unless some
physical difference could be detected inside the brain) since from birth,
one learns the name of a color by others pointing at it and telling you what
it's called...... Men would simply point to what women see as red and call
it "red" too, even though inside their brains it would look to them the same
as what women would call "blue".

Another example that comes to mind is that of the guy who made a pair of
glasses that turned everything upside down and backwards. After wearing them
for about a week, he could do everything that he could do before he put them
on. He could read and write, and even drive a car. On the other hand,
intelligence is a factor, because he made a small pair and put them on a
chicken. The chicken would have starved to death standing on a pile of grain
had he not removed the glasses. The poor creature never even learned how to
pick up a mouthful of food from the ground......

Well if you want to get nitpicky...
....then it changes actually only changes the recorded dates of the recorded
history of photography.

Watched a show on Discovery about Stonehenge a few weeks ago. Apparently
the circle was actually "restored" in recent history (in the 1800's
IIRC).

Personally I find pyramids far more interesting...

I've wondered about this myself, but surely physics must come into it?
The colour spectrum is simply lightwaves moving at different
frequencies, isn't it? The frequency of Red is a lot lower than that of
blue, so if we were seeing blue instead of red, logically we would see a
lot more of the colour spectrum than women can. But that's definitely
not true. Ask any woman!

I have a hard time telling certain greens from blues (torquoise??), but
that's because green and blue are much closer together in the spectrum
than red and blue.

Interesting. Made me think that it could be some sort of autism-
related link. Something that made the blue of the shadows more
vibrant, almost too much to handle, or made colours like textures
the way some people link colour and sound. I see there are a
number of google links on such theories about him, including
what looks like an interesting book.

Ha!!

That's the first time I've ever heard of anyone other than myself who had
thought of, and/or wondered about that. I remember thinking of that out of
the blue many years ago.
Later, I decided in my head that it wouldn't work, since I *think* it would
follow that color-mixing would produce new colors that wouldn't jive with
both people's odd perceptions.

I think there might be some other light-related issues there...

-But it just tickles me to hear someone else utter this exact same
thought...

I'm thinking we may be related, William...

I wonder if a guy wore them long enough...whether the brain could eventually
flip everything (??).
Surely experiments have been tried on this (?).
As for the chicken...I think it would require a human self-awareness that
allowed recognition of what was going on in the first place, rather than
simply existing in what would have seemed a drug-induced haze.

I'm not surprised you get into arguments when you don't know the facts.

Not much of a geologist, are you? Stonehenge is built on chalk.

"Wet British soil"? If it's clichés you want, perhaps the rain dripping
from our bowlers makes the stones difficult to see, especially when
holding a cup of tea in a pea-souper.

I don't know about stonehenge, but the pyramids were built by AMAZING

Yes, that's exactly what happens - it take a few days IIRC. Then it
takes a few days to flip back when you stop wearing the glasses.

Well, I don't know what you mean by the brain, "flipping". Once the
image/color/whatever is inside the brain, it becomes a bunch of electrical
impulses in the dendrites and neurons, and concepts such as flip and color
frequencies lose their meaning. Sometime after we are born, we come to
associate a particular collection of neural impulses with a name that our
elders hang on it. Whenever these nural impulses are being received in our
brains, the elders point at them and say, "See the pretty blue color?" So we
come to associate that paticular set of neural signals with the color,
"blue". Beyond that, I guess the concept of "seeing" the color has no
meaning......

By flipping, I've referring to the possibility that if one wore glasses that
turned everything upside down...whether our brain could eventually "flip"
the image so that it again appears right side up.
After all...the brain already interprets the upside-down image on the back
of our eye. I'm just wondering if it could adapt to an image that would be
the reverse of that.

It does, after many years of View Camera use I pause when other people
inform me the image is upside down. I never see it that way on the GG
anymore.

A true test of his intelligence (compared to that of the chicken) would be
to see how he could handle wearing them every other day, or every other
hour. Could he "switch" back and forth more and more easily, just as a
parking lot attendant can alternatively drive automatics and stick shift
transmissions?

Yes.....Well, bear in mind that the image on the retina of the eye is
already upside down. So the brain, "flips" it once already. But again, this
becomes a meaningless concept once the information is just a bunch of neural
impulses. Nobody's brain processes these signals in exactly the same way as
another's, so we just learn to use the information we get to our advantage,
no matter how, "scrambled" it is, as long as it's scrambled the same way
every time. The fact that this guy could adapt to the rescrambled image in
less than a week tells us something. Namely, that the human brain is a very
adaptable organ. Much more so than that of a chicken.

One of the more likely theories with regard to van Gogh's vision has
to do with his medication: he is reported to have been taking
digitalis, which turns most of the turnable features (teeth, sclera)
of a person yellow after extended use. Deadly nightshade.

I don't know about stonehenge, but the pyramids were built by AMAZING
astronomers.

Perhaps, but every house I have ever lived in has to have it's doorlatches
taken off and filed down every few years or the doors won't latch properly.
And some of these houses were in NYC, and built on bed rock. I don't see how
they can assume that those huge stones haven't settled over the years, and
if there was any settling, then how would they know exactly where they were
several hundred years ago? Frankly, I don't believe they could know, so I
believe their assumption that it was built by ancient astronomers is just
that....An assumption, and not a fact.

And, furthermore, even if you are right, and the "chalk" upon which it is
built precludes the fact that it may have settled, then why haven't the many
(and there have been many) "experts" that I have spoken to about this
pointed it out to me? They haven't, because they have never thought about it
before. Which has told me something about their ability to reason, and has
destroyed their creditability with me. IOW, even if I am wrong, in a very
real sense, I am right.....It is not wrong to require a certain minimum
amount of intellectual honesty from those who set themselves up as
authority.

I must caution you that anything you say will be taken down mucked about and
then used in evidence against you six months from now when you have
forgotten an important date.

The fact that a "normal" brain will flip the image (or for more precise
terminlogy, make it appear to be right side up) was established by a
study more than 20 years ago.

The study was documented on a PBS "Nova" show in the 80's, but I dont
remember the episode number or name. It covered the idiosyncrosies of
vision of Frogs, Cats, Dogs, and humans.

If I recall, the time period to adapt was more than a few days, and
removal of the glasses required the same time delay to get normal vision
back.

Of course not. They were aligned with what once was a runway. :)

I think I read about this is in Scientific American several
decades ago. And little bits of it surface from time to time in
magazines and newspapers. If you can find one (such as in a
library) you might want to look through a Scientific American index.
They've published several.

Are you referring to the South American plain of Nasca, or some such?

Nice mystery.

That reminds me of the difference between driving on the left or right side
of the road in different countries.
-I had a friend who, along with her husband, was killed when a driver from
Australia forgot which side of the road to pull onto when making a turn here
in California. They collided head-on, killing both my friends. The Aussie
survived...

Thanks.

Another post referred to a film on the subject, as well.
