No, you can print copies of postage stamps as long as they're
above or below a certain scale.  You can't print them at 100%,
or close to it -- the range in which it might reasonably be
mistaken for a postage stamp.

There probably are, but I don't know them :-).

First of all, make sure you know your camera's metering pattern.  If
you're shooting someone's face with built-in spot metering (and the
spot is aimed at their face) you should get the correct exposure no
matter what the background is--unless there's too much flare.  And, of
course, if the person is caucasion, their skin reflectivity is
approximately 36% so you *did* remember to overexpose by a stop,
right?  What if they're black (how dark?), or they're caucasion but
they have a really good tan?  Now suppose your metering pattern is
center-weighted average or x-zone evaluative or etc.  How much
background is in a metering area that accounts for how much weight?
How bright or dark is the background?  Why is abbreviated such a long
word?  And what exactly is "occasional irregularity"?  Have you pulled
your hair out yet?

I guess there's no substitute for experience.

Fortunately, modern cameras do an amazingly good job of finding an
acceptable exposure for fill-flash.  However, they can be fooled.  My
personal "general guidelines" vary a lot depending on the situation
but if I had to sum them up I'd say (when the metering area spills
into the background):
  * brighter background:  +2/3 stop to +1 stop
  * really bright background:  +1.5 stop to +2.3 stop

As they say, this advice is probably worth what you paid for it. :-)

   While I haven't seen every single posting in this thread, the ones

   The stock photo business is not about manipulating photos by computer.
   If you are going to market stock photos, the basic things you will 
   want are good (1) database programs, (2) word processing programs, (3)
   accounting programs.  You can get packages that attempt to offer
   combinations of the above, or you can mix and match your own.

   There's not a single market out there for stock photos -- rather there
   are many niche markets.  What type of computer support will work for
   you depends a lot on what you are comfortable with -- and exactly
   what you are trying to do.

   To me, a highly portable computer is much more important than
   image manipulation capability.  (Though my portable is not my
   primary computer.)  It's very important to me to be able to write
   (including taking notes) and communicate while on the road.


   I'm not saying there is not a market for computer-manipulated
   images.  But, rather, that it's a very specialized one.  To
   compete with the big folks there, you are going to have to make
   a really substantial investment.  While some stock agencies are
   producing sample catalogs in digital format, I don't know any
   major publishing markets (other than clip art markets) that are
   actually marketing pictures in digital format at this point.



Although this is not stock photography, here's one implementation of a Mac
for photojournelism:

Take a Mac notebook, Nikon slide scanner, modems and a complement of
Mac and image processing software. Take the pictures at the Olympic,
develope the slide pictures, scan it into a Mac Notebook. Tranfer it by a
high speed modem with data compression. Get it on a mac in the office,
view it, manipulate it, perform color separation, send the file to
printing. Within minutes it is ready to be printed on the newspaper in
color. This is done currently by Newsday in LI, NY. Other newspaper
are doing this also.

I'm sure we'd be delighted to see the August (in all senses of the word) 
winter shots from our antipodean colleagues. I rather doubt if they'll be
able to participate fully in the swap, though (since it does require a 
physical transfer of prints, or at least it has in the past). Perhaps
there should be separate swaps for each continent?

Some of us don't live in "urban" areas, either - but I wouldn't want
to exclude those themes.

This is not entirely acurate. I believe what you are refering to is making
*photocopies* of currency, which you are allowed to do so long as the
photocopy is something like at least 30% larger or smaller than the actual
bill. I suspect one reason for this is because, (never tried it myself you
see), a good photocopy is likely to pass right through a change machine.
The other kind of *copying* that is illegal is of course counterfittig which
is a special kind of copying having other implications such as intent to
pass of as the original.

So... 6x7 works, but how about 6x9?  What's the absolute max?

This sounds right to me.

This doesn't.  The shutter curtains have a random pattern on them to
make their reflectivity similar to typical film emulsions.  

The center weighting is done in the sensor.  It doesn't know whether
it is looking at film or curtain, so the curtain has a random pattern
on it, not a "center weighted" pattern.

It seems theoretically possible to recharge lithium 2CR5's if the charge rate 
is slow enough so as to avoid the buildup of heat and explosive gasses.  After
all, discharge is simply an electro-chemical reaction and should thus be 
reversible if done slowly, say at a 30ma charge rate over several days.
A simple, adjustable trickle charger should work fine for this.

Am I missing something?  I'd appreciate some input before I go blow up my

All this discussion regarding investing in equipment has got me thinking.  Are
we possibly looking at a different definition of "investing" than the typical
MBA definition of seeing a monetary gain?  Consider:  my Dad bought his
Hasselblad equipment new 45 years ago and I know that I could not hope to replace
the system for what he paid for it.  It still works as well as it did when
he bought it, and still looks pretty much like it did 45 years ago, save maybe
a scuff or two.  Can the same be said for the low end (Kodak Brownies, etc) that
were available 45 years ago?

To me an investment can be money spent on an item that is expected to last a
reasonably long period of time.  For example; I buy a newspaper, or an audio
tape or CD, but I invest in a car, or an expensive camera.  That may not be a classic
example of investing, but that's what I think of when I hear people say Hassies
are an investment.

I went out last month and bought the Jobo CPE2 starter kit and
FlexiColor chemistry.  With this set up color processing is about as
easy as B&W.  5 minutes preheat; 4 minutes developer; 9 minutes fixer;
3 minutes rinse.  The retail cost was about $600.  I could have done
better through mail-order.

The processor eliminates most of the temperature problems.

I've experimented a bit with chemical concentrations and found that I
could use concentrations between 1:2 and 1:9 and get acceptable
results (for my purposes) by increasing the development time from 3:15
to 3:45.  This seemed pretty flexible to me.

I'm using normal, moderatly hard tap water and a stopwatch.  Again,
the results seem okay to me.  I can't recall offhand exactly what
chemicals are used, but the documentation said they weren't especially
toxic.  I haven't even put on a pair of rubber gloves or turned on the
exhaust fan.

One of the nice features of the chemistry I'm using is that it can
also be used for RA4.  In the 1:9 ratio, I use the chemicals once and
toss them.

Haven't decided yet whether or not I want to continue doing C41.  I
was only playing with it because the processor and chemistry allowed
me to.  Figure I'll probably continue to get commercial processing
done, which usually includes two proofs of every frame. :)

 I suggest that you follow the manufacturer's recommendations - 
 and bracket a lot.

 Note that the Kodak rating of 50 is for a #25 red filter,
 BUT you don't meter through the filter. Kodak assumes that you
 are using a separate hand held meter. A rating of 200 may work
 if you meter through the filter, but bracket, bracket, bracket -
 and keep notes.

A cheap Bogen strap can be made by buying a 5/16 or 3/8 inch eyehook, one
of those numbers is correct, and putting it in the tapped hole near the
rotating collar.  Then take a standard camera strap, wrap one end around
the closed legs and make a hole in the strap where the end clip meets the
strap, connect here, and put the other end clip through the eye hook in
the tapped hole.  The yehook also kakes it easy to hang the tripod on the
wall when not needed.

I would not recommend the bags made by bogen as you have to remove the
handles to fit the tripod in the bag.  Those baga are OK for small
lightstands and umbrellas.

  AHA!!  If you are using an AI lens, then the symptoms you describe
  indicate that you have the camera's automatic indexing lug flipped
  up so it doesn't engage the AI ridge on the lens.

  This was a feature on the FM, among other Nikon models, to acommodate

If you want some information from a Kiew user :
I had a 80 first. Looks like a blad and is a piece of crap ( MINE was... )
I switched to the 60. Bought some carl zeiss jena and pentacon lenses.
This camera NEVER gave me any trouble. ( Except maybe from the weight, as
this is no plastic junk most people seem to like... )
The good thing on Kiew is :
I paid less for my whole equipment than a friend of mine for one of his
blad lenses - and have at least as much fun from it.

The one I've got is a Plaubel Peco Junior 6x9 monorail made in the early
50s, and it wasn't very expensive: 300 pounds (1992) with a 90mm Angulon,
203mm Wray, and an assortment of lensboards, screens and filmholders.  It's
a bit limited in its movements compared with a normal monorail, though:
shifts on the front and swings on the back.  "Small and light" are not the
first words that come to mind.

What I'd really like for it is a 47mm Super Angulon (either the f5.6 or the
f8: preferably the latter becase it'd be a lot cheaper).  Anyone ever seen
one on the US second-hand market not attached to a camera?  If so, what did
it sell for?

(And, as I mentioned before, the other thing I'd really like is a Graflok-
compatible 35mm panoramic film holder - surely they must have been made at
some time?)

This line of thought culminates in the Ilford K1 Monobar of the same era:
the only 35mm monorail ever made.  They fetch about 1000 quid now.  Must
have been hell to see when setting up.  Did they come with a voucher for
a free lifetime supply of aspirin?
