Subject: Re: Different Films and Pro rated speeds ?
Date: 14 Sep 92 16:11:09 GMT
Organization: University of Illinois at Urbana

In response to earlier articles on this thread, I offer
the following. 

Reala is 100 speed.
Ektar offers a 1000 speed.
Kodak Gold is sold at 1600.
Ektar 125 was a film which was targeted at the mass market.
The general consumer of Ph.D (push here, dummy) cameras
was easily confused by the 125 rating, since *all* other
films they saw were rated at 100.  Kodak changed its
marketing strategy, but, from what I understand, the film
didn't change that much.

I own a Cullman Magic 2, a heavy Bogen/Manfrotto tripod and a homemade
gunstock.  Which one I use all depends on what I'm shooting.

The Magic is very lightweight, folds flat, and can double as a monopod.
However, it is not steady enough for anything but a P&S or a light SLR
with less than 135 mm lenses.  Nice for snapshots of the family on vacation.

For serious shots, birds, animals, closeups, scenery, I almost always use 
the Bogen/Manfrotto even though it is a pain to carry.  (But it is even 
more painful to look at those fuzzy pictures the times I did not use it :-)

In some cases I prefer to use the gunstock with the 400mm for bird or animal
photography.  It is much easier to carry through a dense forest, and you
don't need time to set it up.  Just raise it to your shoulder and fire.

Torn between weight and stability, I'd pick stability every time.

Well, you can stack filters if you want to, but that is like a doctor
treating the problem not the cause.  You might want to make sure you
dont have "flat" negs by checking your meter, maybe using filters,
(orange/red) and properly setting your film speeds.

If you really need to print those flat negs, dont stack filters, get a
contrasty developer with contrasy paper.  Better yet, stop shooting
flat photos!

The other difference is the one in feet is of course
out of date.  We're supposed to use the metric system long
time ago.  But to be on the safe side you might want to
make sure that you'll get a US warranty if you choose
to buy the one with the meter scale.

There is a different imaging rate between film (18 or 24 frames/sec)
and video (30 frames - 60 fields/sec).  The result of conversion on
one of the inexpensive rear-projection devices will have a noticeable
image pulsation or flickering due to the difference in rates.

Professional film-to-video converters have special provisions to resolve
this difference.  Some use a sample-and-hold CCD array, older technology
uses a special shutter in the projector to present 60 images per second
and run in sync with the video (180 im/sec for 18 fps conversions).

Anyway, my recommendation is to send the film to a professsional lab
that specializes in conversions.  I have used Fotomat in the past.

Date: 14 Sep 92 13:21:20 GMT
Reply-To: luong@sophia.inria.fr

Hi,

Two questions:

1. I shot an important roll of Velvia at 80 asa. Should I have it
 processed normaly, or should I ask for a push-processing ?

2. I began a second roll in the same conditions. Should I finish it
 at 50 asa, or stick to 80 asa ?

For information, the problem was caused by a feature of the Nikon 8008
that I find nasty: DX code is *not* prioritary over manual setting of 
film sensibility. I shot a Kodachrome 64 film before, and used the manual
setting of sensibility to expose it at 80. Then I removed the batteries 
for almost a night to reload them. However, the manual setting at 80 was 
still there, and I forgot to check.

Thanks in advance

Hi:

First of all, thanks a lot to everyone who has responded to my plea for
help in choosing camera and a lens.  Based solely on advices from people
here I purchased an ELAN with 35-135USM, and I am quite happy with both.
Thanks again.

	Here comes the problem and a question.  I thought that the flash
that comes built-in _will_ significantly reduce red-eyes.  Wrong guess.
Red eyes are there quite often.  Therefore, my assumption is: I need
a bounce (tilt-head) external flash - but which one to choose?
Choices range from abpout $100 for a Vivitar up to $320 (retail) for
430EZ.  Although I do not mind shelling out $300.00 for a thingy if
it is worth it, I still would like to know: is it?  What other worthy
alternatives are?  I shoot only my family and  some travel scenery.  Since
my primary "model" is my 7.5 y.o. fury, I have no way to choose a
tripod over a flash.

	Thanks a lot in advance.

	I would prefer E-mail, if possible.  I will post a summary.

Add one more to the list: old film. Some people think it's fine to use

Yes. The 100-300 will be of simular quality to the 35-105. The Canon 75-300

If it is quality you are after,go for the 100-300, or save some more for the
100-300L, which will blow all the others into the weeds. Don't take too much 
notice of APO or the like, made in marketing, and pretty meaningless, except
as a means of differentiating different models. Microscope lenses seem to be
the only ones that 'apo' has any real meaning nowdays. :-(

   First, it is definitely not a waste. You may be pleasantly 
   surprised at the quality of the results. The peculiar thing
   about a Zenit (this was at least ten years ago, so I do not
   recall the model number) is that there are two rings for 
   the aperture. On one you set the aperture. You then turn
   the **other** ring to close the aperture. If you forget 
   to do so the exposure is at maximum aperture regardless
   of what you set it at. Takes quit a bit of time (and 
   wasted frames) to get used to this feature.
  
   I posted this on the net so that users of Zenit may wish to
   add to or correct my version.

I agree, except I also like Ektachrome 400X much better than
Fujichrome 400.  IMHO regular Ektachrome 400 is really "icky" film,
but 400X is clearly better than Fuji RHP in terms and grain and
sharpness and pushes very well to 800.  I have not tried Ektachrome
400HC.

All are in good condition with the exception of the 80-200mm.  The focusing
/zoom ring is slightly loose from wear, and there is a small amount of
dust trapped between a few elements.  For this reason, I'll sell the others
as a group without the lens, or with it, whichever you choose.  Either way,
the lens still takes good pictures for the price I paid for it...

Subject: EOS-5 and Canon 35-350 zoom.
Date: 13 Sep 92 17:09:33 GMT
Organization: Carnegie Mellon University

According to the Sunday New York Times the big announcements from Canon for
the Photokina are the EOS-5, about which there has already been some speculation
on the CBS This Morning thread, and a new zoom lens.

The camera uses an eyepiece tracking mechanism, as has been already mentioned,
but it consists of five small rectangular regions across the center of the 
viewfinder.  This implies that it looks like a set of copies of the normal AF
sensitive (horizontal) region arrayed across the center of the field.  The idea
is great, the implementation is frought with possible problems that will have 
to await test reports.  The primitive nature of a single focussing line does not
address the issue of off center focus in the two dimensions of the field.  The 
military targeting systems do.  There is a danger that the focus sensor resoultion
is diluted even further beyond that already used for mixing horizontal and
vertical edge detectors in other camera designs.  Thusfar there are no reports of
a quantum leap in the number of sensor elements laid down in a chip 
(typical numbers are about 256).  A small single sensor has a higher resolution
per unit finder area, and implicitly is better able to focus accurately.  How
well these systems cope with eye sicade, and require fixation before making a
focus rectangle selection, will be interesting.

The new lens is an EOS design 35-350mm compact 6 1/2 inch design, variable
aperature f2.8-5.6, 6 element, one stationary. Built in hood.  Pretty remarkable
to have a tiny design with a 10 fold zoom range, regardless of whether this is
a consumer lens.  At 135 mm the closest focus is 2 ft.  There is a special cam
design to avoid creep when the weight of the lens might change the focus or
zoom.  It is a single control design.

No prices or availability dates were announced.  See the Camera column of the 
NYT 9/13 edition for the complete article.

The K-Mart stores around here send their film to Qualex (as do many other
retail stores).  A few weeks ago, I spoke to the Q.A. manager at Qualex
headquarters in North Carolina to find out why they use Kodak "Edge" paper
(the most constrasty RA-4 paper).  He said it was a corporate decision and
they were working with Kodak to try to tame the contrast.

I have not used K-Mart or Qualex, but I have seen other's pictures.
