The July issue of Shutterbug had a series of articles on B+W.  One of the
writers talked about how he had a display print made and the final step
was where a 'finisher' came in and bleached the highs.  So i think
the technique is still used.

I assume you've sent a letter of complaint to Pop Photog on your problems?
They can't document trends of problems if everyone sits in their back yards
expecting other folks to send in complaints so they don't have to. If you
don't think they should be check rated, then write and say so. If you don't,
you go not complaint if PP never does anything about it.

I have experience this problem several times.  This happens at bike races --
especially when the lead car comes around the corner.  The AF mechanism needs
contrast to AF and can not AF on an item without any detail like a white wall,
hood of a white car, side of an airplane, etc.  I know of nothing else to do
except to take the camera off of AF.

I was planning to get a 70-200 or so lens (for Nikon AF)
when life got complicated.

Earlier, there were two options: UC and APO.  The UC was supposed
to be cheap and terrible, the APO was supposed to be good.

B&H no longer carries the APO.  Makes me suspect that it's being
discontinued.  Most shops still advertise it: is that old stock?

Now there is a 70-210 "ABUC" (f4-5.6).  What does this mean?
It's $190.

There are two options at 75-300: a APO and a "DL".

What do you suggest for one lens among these three or four
alternatives?

I'm looking for a basic B&W enlarger. I don't know too much about enlargers
to begin with. I can pick up a used MEOPTA OPEMUS 5 without lens for
$80 Cdn, and $30 Cdn for a 80 mm lens.  I realize that with an 80mm lens
I'll only be able to make 5X7 prints. Thats ok for now but I'd rather have
a 50 mm lens.  The enlarger itself is in good shape and seems better 
constructed that the econo enlargers in the photo stores.

I'm not looking for anything great. Cost is a big factor. Anyone have any
comments on this enlarger. I have seen the MEOPTA OPEMUS 6 in 'the dreaded
CAMBRON ads' for $149 US.

Quick replies would be greatly appreciated since I have to make a decision
quick.

From Kodak, where else?  That aside,

Aerial and Aerographic duplicating films are sensitive down to 300nm.  We use
10x10 aerographic dup films with both cw and pulsed laser sources to 351nm.

The dup film comes mostly in large format size and very high resolution
(upwards of 800lines/mm) to be able to copy the very fine grain aerial films
which come mostly in rolls.

To go beyond 300nm, you would need a film with no gelatin overcoat.  These
used to come in rolls and at $1,500/roll (min 18).  Kodak discontinued these
last year.  However, they still make spectroscopic glass plates which are
harder to put through a camera (although I've tried and succeeded).

You'd have better luck putting together a competing system from scratch, 
since most of the hardware in the Photo CD system is available in various
forms "off the shelf"; scanners, CD-writers, thermal printers, computers, etc...

You can try the test image approach, but any mathematician can tell why it 
won't work.  However, all you really need to do is buy a system and take it 
apart, right?

Sorry to take such a sarcastic view, but wouldn't you all be better off 
devoting your time to a more worthwhile endeavor?  Like for example, convincing
all the camera manufacturers to make their lenses interchangeable?  Naaaaa.

Most disposables that I have taken apart include a spool that the film

Also make sure to reset or remove the frame counter, or the camera may
not advance properly.  This is done by unsnapping the top panel of the
camera and turning the frame counter wheel back to its original ("as

Is there a practical way to use the zone system, by which I mean using varying

something by fogging certain frames with a piece of ground glass. Has anyone

Organization: NEC Research Institute

I forgot to save the long post about the features of the new Nikon N90,
but I thank the poster for the info.  After reading through Nikon's 

technobabble, I had to go shoot a role of film with the old FM2.  I was
even tempted (though I didn't go through with it) to take the battery
out and rely on my intuitive feel for the film response and lighting.
What a great thing in today's world: a camera with shutter speeds down
to 1/4000 all of which function without batteries!

Don't get me wrong; I own a Nikon 6006 and use it extensively.  It does
have several advantages over the FM2, but I do not count multi-segment
matrix metering or program modes among them.  To me, the only really
useful new features of the modern AF cameras are:

1. TTL flash metering -- takes much of the guesswork out of getting good
flash pictures in a hurry.  I realize this can't be done with an
all-mechanical shutter.

2. Built-in spot meter -- great for emphasizing certain portions of the
photo, and in low ambient light situations.  Why can't Nikon add this to
the FM2n, and come out with an "FM2ns"?

3. Autofocus -- useful when you need to shoot fast, shoot moving
objects, and in dim light.  But AF can screw you up when you want to
move the depth of field back and forth, and when you want to use the
hyperfocal length (those AF lenses lack useful DOF scales!!)

So is it just me, or do other feel that the zillion-plus-one whiz-bang
high tech features being packed into cameras like the Nikon N90 or the
Minolta xi series to be more distracting and intimidating than useful?
(and I make a living out of high tech electronic stuff).  Does this
stuff really lead to better photos? I imagine that in the time it takes
to read the N90's manual, a novice could fully understand f-stops and
shutter speeds and get a good feeling for the characteristics of a
simple center-weighted meter and be off taking really good pictures.  Or
am I just too old-fashioned?

For the lens, go down to your local hobby shop and get a bottle of Humbrol
'Maskol' or simular. Pactra ect should have simular. It is a liquid mask for
painting plastic models. Sort of a thin rubbery stuff. Stick this over the

so you can peel it off easily. You can also keep track or the lens alignment

Evidently Nikon isn't making this lens anymore,
or will soon discontinue it.  Unlike man of the other
Nikkor zooms, the speed of this lens changes
with focal length.  This can be a pain, but the question
how do the optics of this lens compare, say to 
the 80-> 200 f4.5 AIS zoom?
