Watch the Olympic opening sequence to see how many morons think a puny
on camera flash can illuminate an olympic stadium at night time.


They have no idea how the flash works, and no idea how to turn it off
anyway. Their camera is always set to auto, and simply fires the flash in
such circumstances, because it has no idea either.
Still remember the moon landings where millions of pictures of blank TV
sets were processed in the following weeks. The flash exposing the
cabinet just fine :-)
At least the morons get to see their mistakes immediately now, knowing
what (and how) to change is entirely another matter though!
And I can't count the number of times I've helped people with expensive
DSLR's that have no idea how to change even the most basic settings!
Their comment is always the same, "must read the manual one day". They
never do :-(

I've seen a lot of them taking flash photos of fireworks. That's double
stupidity.


Like the stadium shots, the flash won't ruin the shot at least. Of course
their slow exposure without a tripod will usually do that for them though.
:-)

I shouldn't bother, but I'm going to call your bluff. Please tell us what the
first two infinite numbers are


"inifinity measured in miles" and "infinity measured in meters"
(or kilometers, or Planck constants, or sizes of the universe)
are all exactly the same.

For photography purposes any long enough distance has no
difference to infinity, no matter how you measure such
distances.

and why the second is larger than the first.


That you will have to ask the one who made the claim, a certain
", unless you want to sponsor me a mind
reading course.


Or were you talking about aleph-null and aleph-eins? In
which case --- no, they're not *numbers*, they are *sets*.


I
won't even ask you to prove (although it has been proven) that there is no
number between them.


That depends entirely on your choice of axioms and choice
of definition of Aleph-eins. If you define the latter as
the smallest infinite *set* larger than aleph-null, it's
by definition; if you define aleph-eins as the set of real
numbers, you need to prove the continuum hypothesis --- which
is a ... bit problematic, unless you have fun with additional
axioms.

And between them the two *sets* aleph-null and aleph-eins
still have infinite numbers, uncountable infinite numbers,
to be exact. :-)

You are winning the prize as the most comedy-challenged poster in the
history of rec.photo.digital.slr-systems.

Good work, Wolfy!

Of course, that performance in itself is ROFL material.

No, they are not sets. They are the (infinite) numbers of *members*
incorporated in two different sets. I leapt to the conclusion that transfinite
arithmetic is beyond your reach, and you seem to have proven me correct. (But
you do get a few points for Googling the concept, which allowed you to
maintain some minimal pretense of understanding. Very frankly, I didn't think
you would manage to do even that.)

BTW, in an English-speaking newsgroup, you really should refer to "aleph-one"
rather than "aleph-eins". (Auf Deutsch, aleph-eins ist richtig,
natürlich.)

So tell me, what are the first two infinite numbers? You
seem to be bursting to tell everyone how smart you are!

Your skill in judging people is unsurpassed.

So you'd advocate "aleph-zero" in an English-speaking newsgroup,
too?

No, I'm giving you an opportunity to show us how well you understand
transfinite arithmetic. How can it be that one of the numbers (aleph-1) is
larger than the other (aleph-0), given that both of them are infinite? The
proof is actually quite simple. If you're stumped, Wikipedia must surely have
it.

Not necessarily (although I have heard it called that). The word "null" is
just as understandable in English as it is in German. In the math class where
I first encountered the number, the professor called it "aleph-null". And
aleph-1 was referred to as "c", which stood for the "cardinal number of the
continuum". I'm not even certain that at the time (the late 1950s) it had been
proven that there are no other numbers between aleph-0 and c. I've since read
that it's now known to be the case (which may account for the adoption of the
term "aleph-1"), but I don't recall seeing the proof.
