Ascending while holding your breath (a breath taken from a tank at a

affect-

It can cause an air embolism, which means the air bubbles in your blood can
expand to the point where they block your blood vessels.

as the enclosed air in your lungs expands under decreasing pressure.
If you take your breath and hold it a tthe surface, descend and then
ascend,
there is no problem with that as your lungs are at capacity at the surface
already.

The "bends" result solely from too rapid an ascent, whereas holding your
breath is a problem no matter how slowly you ascend. The two are both
dangerous, but are not the same thing.

Otherwise, your point is accurate as far as I know.

Could that also happen with a breath taken at the surface? What kind of
conditions would cause this?

It can happen, from what I remember, anytime time you take a breath from 4
feet or more under the water and then ascend without exhaling. Took dive
lessons in college for PE requirements, but that was a VERY long time ago
:-)

That doesn't bother me. It's when they say "I REALLY have to go to the
bathroom!!!", and the piddle-packs won't solve the problem.

One thing I've found makes a HUGE difference with digital photography is
to
NOT get the wing in the picture.

Actually, that's not a "digital photography" thing. There are a number of
digital cameras that won't have that problem, and a number of film cameras
that will. It all depends on how the autofocus works, and how you use the
camera.

My digital camera, an Olympus, has an infinity focus setting that overrides
the autofocus.

Isn't that why the miracle drug, Pseudoephedrine (aka Sudafed), was

I always keep at least cruise power on when descending, until I descend
low enough to maintain 2300/23", gradually enriching the mixture as I
descand. I like to start descent 20-40 miles out, letting the speed
increase, to make up for speed lost in climb. With normal cruise about
150 mph IAS at 10000, I can build up to about 170-180 MPH on descent (no
worry, because redline is 230 MPH). That way, there is no spiralling
down at destination or cylinder cooling.

Not with my camera, the Olympus E-10 has a aiming dot, the focus is where the
dot is. My aiming point was actually downtown Phoenix but its so small your
can't see it in the picture.
Its actually just pretty hazy there from higher altitudes, SoCal is the same
way.

This picture I took over Oklahoma, I was at 8500 ft I think, it has the wing in
it but the colors are good. I could touch it up with photo shop but it would
take the natural look from it.

I actually prefer flying over the midwest area, flying was great, there are
actually things to see, not like the desert, where it all starts to look the
same.

There is allot less color to see on this side of the country.
We use an the Olympus E-10 digital camera for pictures.

One thing I've found makes a HUGE difference with digital photography is to
NOT get the wing in the picture. My digital autofocus usually locks onto the
wing, and makes everything else in the background (which is what you're
aiming at!) look fuzzy.

Also, Photoshop does a much better job of adjusting color, brightness and
contrast if you don't have a big, white wing in the picture.

Olympus makes some nice cameras.
The new E-20 I think it is, is suppose to be super crisp. We payed $1800 for the E-10
and it does everything we need so we didn't upgrade to the E-20. The E-10 has more
functions then we actually use.
