Starry Night?

Gary asks:
"I have a serious question I need answered. Whenever the space shuttle astronauts take pictures why can't we see any stars in the background anywhere?
Also when they landed on the moon and snapped pics of the earth, where in creation is the stars at? This has always troubled me because at night I see the stars but when they snap photos in space it's all black.
Please explain? This is something I've never understood?"

I'm not sure. It could be because the moonlanding was fake as some say. Or it could be because they were photographing sun-lit objects (the Earth or the Moon), and so the stars are too faint to show up in comparison. When you see the stars at night, there are no huge sun-lit objects to cause your pupils to contract.

Oooh, I just remembered, back in school we were told that if you stand at the bottom of a well, you can see stars in the small piece of sky above. It didn't make sense to me back then because I thought it was the blue of the sky which was too bright for the stars. But if instead it is the daylight on the landscape around you doing it, then that datum makes sense.
... I still don't quite see why the sky would not be too bright all by itself to show any stars though. Ah well.

Cameras in the Antarctica


Interesting article about how cameras hold up in the Antarctic. One funny point is that buying the most expensive gear is no guarantee. Amongst 50 photographers, several had camera failures with Canon 1Ds, and several with Leica M8, both of which cost many thousands of dollars just for the camera body.

I also find it ironic that the author, Michael Reichman, has earlier in an article adviced us to not fear shooting in the rain, even with cameras which don't have special all-weather seals. But most of the camera failures described in this article happened during shooting in the rain in the Falklands. And several with cameras which do have all-weather seals, like the Canon 1Ds. (I'm frankly a little surprised about this, for this camera is used all the time by press and sports photographers shooting in all kinds of weather.) I am reinforced in my decision to not shoot in the rain without packing the camera in a plastic bag.

Ex Mente Orbis

Ex mente orbis:
"From the mind comes the world"

A couple years ago I was recommended two movies by my friend Ken Evoy. And they are indeed both wonderful movies:
Sexy Beast and
Life As A House.

I am rewatching them both this week, and it strikes me that they have something in common: one is about a man retiring from the Hectic Game of it all. And one is about a man who already did this, but the Hectic Game comes hunting for him.

I doubt I'll ever retire in lawn-chair sort of way, but this is resonating with me in another way: What are the rewards of the Hectic Game? Meaning earning big money, getting big status and influence?

Say a man named Bill has been playing the Game like all-git-out for ten years and has made vice president and a big house and mortgage. But he has not had a minute of free time to develop his mind and spirit or think about his life. And say his old school pal Bob has spent the same ten years being unemployed, on park benches and in the library, not earning a cent, but making all kinds of changes and developments to his mind and spirit. Who is the most successful, Bill or Bob? Beats me.

Snow pictures

The alert reader might suspect: I have at least two very strong interests in art and aesthetics: one is lines. Another is patterns. So when a subject like these has both, I get very keen about it.

Don't miss clicking on the more subtle compositions in the middle here. I am very fond of those, but they have to be viewed in a larger size.



I find it cool how the picture above looks almost exactly like a black-and-white picture, but it is a color picture! I have not removed any color from it.






The pictures are slightly manipulated, with contrast and such.
The top one I've put up before, but this time it's larger.

highlights

Digital photography is making amazing progress. There are still two areas though where I hope it will soon leap way ahead of where film is. Those are
1) sensitivity. I want to handhold photos in almost any light. (This area is already ahead of film, admittedly.)
2) contrast handling. Even in overcast whether I still sometimes get pictures where the camera couldn't handle the contrast, and it looks awful.
It seems a step has been made in the latter area by Canon.

Using customer reviews



Customer reviews, like on Amazon, is a fantastic invention. It is one of the things that permit the overwhelming diversity in today's culture (due to digital production and distribution) from being a blessing more than a curse.

But you have to learn how to use them, and how they work. See for instance these reviews on two different sites. Could the average rating be more different?

I think the difference here is a variant of a parameter I have found to be very important: to what degree has the audience reviewing the film/book deliberately searched for it before buying/renting it? I suspect that the renters on UK LoveFilm here found the film by accident and tried it out. And the reviewers on Amazon.com were people who were deliberately looking for movies with the female lead, and so they liked it. And you do in fact find evidence to support this if you take the time to read the reviews rather than just the star ratings.

I find that big-bucks movies which are pretty much forced in your face, Mission Impossible type movies, tend to get relatively lower ratings compared to quality, than more rare movies, especially old ones. Because the only people who buy and so review the rare movies are those who love a specific genre or actor, and so rate it higher.

Before I learned that I was woefully disappointed a few times, for instance when I tried out the horror/slasher genre based on stellar reviews some old films got. It turned out they were dreadful, but only slasher-film-lovers wrote those reviews. Caveat emptor!

1,000,000 aches = 1 megahurt

Most deliberat puns are awful, but these are fun. Author unknown.

Scratches

I rent a lot of DVDs, and a continuing problem is that maybe one if five has so many scratches that it pretty unwatchable.
CDs and DVDs are awesome technology, but come on, it's been over twenty years, how come nobody has invented a disk which does not get scratched if you look at it sharply? Seriously.
Or even just a DVD player, a box or in a computer, which does not keel over and throw its legs in the air in the presence of scratches. How hard can it be to program it to not freeze or crash, but just skip to the next place on the disk which is scratch free?

It seems to be emblematic not just of technology but almost anything human that there are these amazing things, but they always have all those huge, obvious flaws. Weird.

Value

Isn't it funny how solid "value" seems, and how subjective it really is?

Many women would tell me that $4,000 is cheap for a good engagement ring, while I would tell her that that's insane to pay that price for a little piece of metal and glass-like substance which has no practical use.
On the other hand I'd tell her that $4,000 is cheap for a Canon 1D, while she thinks I'd be nuts to pay four grand for a digital camera when I can get a perfectly good one for $200.
Of course in five years that camera will be a door stop compared to newer ones. But it is still worth it to some people right now.

... As for using fifty thousand dollars on a wedding which lasts one day, I better not get started on that one, I can't keep my calm perspective! :)

Maybe it really is like my spiritual mentors tell me, that anything physical is illusory, so the only value it has is whatever you decide it has.

Bugatti Veyron

If the Ariel Atom seems crap to you because it does not have things like doors and a wind screen, you may consider the Bugatti Veyron. On the downside, it does cost sixty times as much as the Atom. On the upside it's a bit faster on the long stretches. (OK, it's faster than a formula one car.) And more importantly (for me) it is one dang gorgeous object. Maybe I can get one for half price if I don't need the engine?


(Don't worry, this won't become a car or technology blog, I've no doubt there are plenty of those. I just have a fondness for extraordinary products of any kind.)

H-h-harm

You may know the old joke:
"I was beaten as a child. It didn't d-d-d-d-do m-me any har-har-harm!"

Funny enough I once met a man who said exactly that, and he was actually a stammerer!

---
Update: I suddenly see why a commentator thought this post was "harsh". Well, obviously I don't mean it's funny that somebody is a stammerer. But it is funny that he was living this joke, and just like the man in the joke he was completely overlooking the very likely evidence right in his face that his statement was dead wrong. It seems quite likely that the terror of living with violent parents could turn somebody into a stammerer.

Speech recognition in Windows

Talking about typing, Pogue just posted this article about controlling the PC and Speech recognition in Windows Vista. It sounds very cool. Perhaps I should get Parallels and install Vista on my big Mac. Even when you're a good typist, it still takes a lot of concentration and corrections. At least it does for me. And Pogue and others say Dragon NaturallySpeaking 9 is "eerily accurate", and that Vista is very close even without it.

OK, I would not imagine it would be good for programming, but somebody had to try. This is funny. (The funniest thing is that the guy starts out making a demo of how easy it is, and at the end, after a million silly problems along the way, apparently still thinks it's a good demo of that!)

Autumn search


A crazy amateur sleuth story.

Quotes by Bette Davis



Quotes by Bette Davis

Acting should be bigger than life. Scripts should be bigger than life. It should all be bigger than life.

I don't take the movies seriously, and anyone who does is in for a headache.


Old age is no place for sissies.


People often become actresses because of something they dislike about themselves: They pretend they are someone else.


Psychoanalysis. Almost went three times - almost. Then I decided what was peculiar about me was probably what made me successful. I've seen some very talented actors go into analysis and really lose it.

Sex is God's joke on human beings.

This has always been a motto of mine: Attempt the impossible in order to improve your work.
