Remember that the "Plastics" used to make modern cameras,
isn't some cheap stuff you would use on a toy, its a
polycarbonate, the kind of stuff used to make bullet proof
windows.

Sorry,
	I posted some misinformation about tung. bal. slide films.  EPY is the
iso 64 stuff and EPT is the iso 160 stuff.  According to B&H they are available
in both 35mm and 120 formats.

I bought my Durst M600 a long time ago.  I opted for the Schneider

The following is the summary of the inputs I received a couple of days
ago on my query about photograhic flea markets in the San Francisco
Bay area. Again my thanks to all that replied.

Alameda, corner Broadway and Santa Clara Ave. (there is a hotel there),
every Sunday morning.
Comments I've got: not very big, dealer prices quite expensive, relative
small selection.

Hayward photo swap, Centennial Hall, every couple of month.
Dates are advertised in local newspaper, classified Flea Market, dealers
at Alameda flea market might know next date or call Centennial Hall. They
maintain a mailing list, once you're on the list you will be notified for
the next date. (maybe someone on the net, who is on this list could post
the next date?)
Comments: more stuff and lower prices than Alameda.

Santa Clara County Fairgrounds, every six month (one date is in April),
usually advertised in San Jose Mecury News (under cameras).

There's a huge one in August in San Jose (is listed in July Shutterbug
issue, I don't have it with me right now, if there's interest I'll look
it up, when I return in two weeks (will be out of town)).

Vijay-

Others have already provided good information about how flashes work.  One
thing that wasn't mentioned, is that the Minolta X-700 is capable of
Through-The-Lens (TTL) flash automation.  If you have a flash with matching
TTL capability, you can put the camera and lens on Program, the flash on
TTL, and let the system worry about the details.

Oh, I think the Pentax digital is the smallest and lightest; perhaps
smaller than most hand-held meters, though shaped quite differently.
It's really the best of the bunch for the zone system in the field, in
my opinion, because it's accurate, reliable, small, light, easy to zone
with, and doesn't bother you with tenths of a stop when you really only
want thirds.  (Some techno-types might consider third-stop resolution
to be a disadvantage, but in real-world photography, I would claim just
the opposite.)

Isn't that kind of like saying 'Do any of these want-to-be-programmers

It takes more than one photon to expose a grain, and if enough of them
do not arrive in a reasonable amount of time, the partial exposure
fades away, and the grain reverts to its original, unexposed state.  I
do not have any idea what  "reasonable amount of time" is.  I believe
it takes four photons to make a solid exposure, though, and if you only
get two or three, you can lose it.

Yes, exactly.

EV 0 = f/1 at 1 second.  You have to know what film speed is being used
to know the absolute quantity of light.  It seems to me that EV 10 is
about 13 candles per foot squared at ISO 100; you should be able to
figure the rest out from there.

Yes.

No.  ;)

(It sounds like you want an "Undocumented DOS System Calls" kind of

I wouldn't think so, since doing so would empty the caps I believe. I don't
know the particulars, but the energy remaining in the caps is somehow
recycled back through the flash circuit.

A good travel agent can tell you how to get a document called a "carnet" 
for your equipment. This essentially pre-arranges customs clearance for the
equipment. I have not done this for photo equipment, but in travels with
electronic equipment, this is the technique used when crossing international 
borders. (The carnet has always been obtained for me by my employer's 
travel service, so I don't know how to obtain one myself). But, just this 
last week I read an article by a commercial photographer who uses the 
same technique for his gear. I don't know how much it costs to get a carnet, 
but it may be substantial.

NO! the other way around. I am looking for a magazine that show the picture

Doesn't anybody wear *hats* any more?  They work quite nicely for

C'mon!  Ansel wore a hat; I wear a hat.  What more evidence do you all

The F4s can matrix meter with a non-AF AIS lens, while I believe the 8008 
will not (because it can't tell maximum lens apeture?).

I love my Zone-VI modified Pentax digital.  Tests (by Richard Henry, in
"Controls in Black and White Photography") show that the flare control
and accuracy are slightly better.  These tests didn't address the color
balance issues.  Other tests, the results of which have been published
by Zone VI, indicate that the color balancing filters really do help.
I have confidence that they do help at least some, in an approximate
way, but I've never worried about color in my exposure determinations
for either black and white, even through filters, or color.

|> Thoughts on the Minolta Spot-F or the (unmodified) Pentax digital?

Both of these meters got similarly high marks in Dr. Henry's tests;
they're both very good.  The Minolta is probably less suited for zone
system work, because it doesn't seem to have a convenient means for
place and fall.  Perhaps I'm wrong; I hope so!  Other than that, the
Minolta appears to be a very good meter, and the ability to read flash
is a Good Thing.
