What Michael Graven is describing is a valid--if unusual--method of
reducing contrast.  In effect what's happening is you're pushing the
shadows more than the highlights.  The extreme underagitation results
in local developer exhaustion in the highlights, but the shadows which
require less developer continue to develop.  

You may consider it an extreme measure, but in extreme low light
situations (which are often very *contrasty* low light) it can help to
keep the hightlights from exploding into an impenetrable block of
silver.

However, I would be very careful that you're not actually
underexposing the film.  You know what they say:  expose for the
shadows, develop for the highli----ack!  Ouch, that hurt!  I guess you
already knew what they say. :-)

I would encourage you to do yourself a favor and switch developers to
Press-Maxx.  I have been using it for about a year and a half and have
found it to be a miraculous improvement for pushing.  With Press-Maxx,
Tmax 400 pushed to 3200 looks as good if not better than 400 pushed to
1600 with Tmax developer.  Also, contrast seems to stay under control
better with Press-Maxx.

Hi there,

        I recently bought a Hoya linear polarizing filter. I am beginner in
the field of photography. I could figure out adjusting the angle of
polarizer to cut off reflections. But what I couldn't figure out was to
adjust the angle of polarizer for getting a better contrast of things say
sky in the photographs. Can any one give suggestions for calibration of the
polarizer filter and tips about adjusting the angle for different lighting
situations. Thanks in advance

It depends on how "in their face" you are. Certainly you can take any
picture you want in a public space, although you can't publish without
permission (I'm talkin' USA here), unless it's "news". (At this point,
it gets hard. What's "news"?)

But if you're really close to the subject and you know they're seeing
you, it might be best to explain what's going on. For example, after
getting a new 10S a few days ago, I was walking through the Castro in
San Francisco and wanted to play with the "auto bracket" mode. I saw
several rather interesting lesbians on the street and walked up to
'em and said "excuse me - this is a christmas present. (gesture) mind
if I take a couple of shots?".

They posed, they batted their eyelashes, and I believe I got a few
nice pictures. (Lots of frames, too. That "auto bracket" eats a lot
of film!)

As I walked away, one asked "will that appear anywhere?" and I responded
"my photo album". I 'spose it was important to let them know that they
wouldn't wind up spread across a local paper....

I have the great fortune of being able to

anyone know if there are any stores that rent
camera equipment, ie lens and underwater cameras??

I can rent locally, Milwaukee WI, but would like to
get an idea of price comparisons and maybe save myself
the energy of lugging the rental equipment some 4500

Also any suggestions on sites, on land and dive sites,
restaurants, dive shops, must see(s) and must avoids, etc??

Any info will be appreciated.

Hm.  Why so much stuff?  If you could pare it down to a body, a 
telephoto lens, a wide angle lens and some accessories, I think I have an  
answer for you.  The trick is to carry more outside your big back 
pack.

First, get two of those quick release buckles and sew the top half of 
each to your shoulder pads.  Make a small camera strap that ends in 
the bottom half of the buckle.  Now you can carry your camera along 
with lens and it's easy to take off and mount on your tripod.

Second, get a fanny pack like the "expandable" one from Eddie Bauer.  
It has enough room for two lenses in foam&leather bags plus film, some 
filters, a cable release, and a table-top tripod.  If you're 
travelling with two lenses, then with one on the camera there's room 
for your extension tubes, too.

Third, lash your tripod to your pack.  Tripods always slow you down, 
having to unlash the thing shouldn't be that big an inconvenience.

I've used a variation this setup for playing tourist instead of 
carrying around my shoulder bag.  It's seen me through a week in 
London, England, and countless trips around Washington, DC and Boston, 
MA.

Subject: SUMMARY (so far) - sources for 5x7 prints
Date: 30 Dec 92 10:38:20 GMT
Organization: Silicon Graphics, Inc.  Mountain View, CA


recently, i posted a note asking for good quality/low price sources for:
  1) "5x7 processing" - develop a roll of 35mm film, make a 5x7 of each frame
  2) "5x7 reprints" - print a 5x7 from an existing 35mm color negative
here's a summary of the replies i've gotten and the checking i've done so far:

mail order

  1) mystic (800-367-6061) - recommended by netters.
     5x7 processing - $12.90/24exp, $16.90/36exp. unfortunately, they tape
       a strip of paper to each negative during processing, which scares me.
     5x7 reprints - $1.50. for reprints, they don't tape on the paper strips.
  2) skrudland (512-444-0958) - enthusiastically recommended by netters.
     5x7 processing - not clear if they'll do it; i'm still checking.
     5x7 reprints - $1.25. i've ordered some reprints; haven't come back yet.
  3) slideprinter (303-698-2962) - 5x7 print from slide - $1.75

local (s.f. bay area)

  1) pro labs (calypso, color plus, jp) - i've had calypso do 11x14's,
     and was pleased with the results. for 5x7's, pro labs charge 5X
     what a mail-order place or minilab charges.
  2) kits (415-321-0321) - only local place i know that does 5x7 processing.
     mixed recommendation from the net.
     5x7 processing - 12.60/24exp, 17.90/36 exp.
     5x7 reprints - $1.00.
  3) minilabs which i haven't yet contacted
     phototime, stanford - mixed recommendations.
     fotomaster, santa clara - insist on having haw lee do the work.

conclusions so far

  5x7 reprints - mail order prices are good; we'll see about quality shortly.
  5x7 processing - kits looks like the only game in town, for now.

i'm still looking, so please email any info you have.

thanks.

On an F-801, none that I know of.  On an F-801s, the manual says that the
microprism screen for F-801 can be used in F-801s but that spot metering is
no longer usable.  I don't know how badly it messes up spot metering.  I wish
I could get microprism around the center spot rather than in it, and also
have the grid outside of that.  Where oh where are the third parties....

	[ tale of battery fading in and out depending on use... ]

I recently noticed similar behaviour on my EOS 630, though not as
severe (bouncing between 2 and 3 bars on the battery check).  At first
I thought it was temperature (it can be quite cold in Toronto these
days).  However, I suggest trying a different brand of battery.

I've been told that "Not all lithium batteries are created equal.".  My
previous batteries were Sanyo (makers of *real* 2CR5 batteries) and
Everready.  Both of these seemed to discharge in a more-or-less linear
fashion.  Interestingly, they were also housed in plastic casings
similar to each other, but dissimilar to my current (Varta) and spare
(Maxell-Hitachi) battery.

The Sanyo and Everready casings looked completely sealed.  The Varta
and Maxell batteries have a horizontal split on the ends of the casing
which look like they can be pried at.

Interestingly, the Varta and Maxell batteries sell for about 2/3rds the
cost of the Everready.  (Now I pause to scratch my head and go, "Hmmmm.".)

So, find a store that carries a different brand and try it out.
Again Sanyo, and I think Panasonic are the "official" 2CR5 battery
makers.  Canon markets a 2CR5 under their own label, but I've never
tried it.

It is interesting to see that Canon can adjust the sensitivity to
voltage.  Are you going to go for the modification?  Did the Canon
rep. say anything about what you'd be risking?

Good luck.  Let us know what happens.

Prices as well as utility would seem to point to the FT3 and the EL2
as the "best" Nikkormats, even though the EL2 has the name "Nikon"
it really is an auto/manual FT3.  Both have a hot shoe, AI lens
compatibility and are still valued in the $200-275 range in nice
shape.  Of course if you want the old "prong" coupling the FT2
is a good choice.
