Ektar films are C41 films.  It even says so on the cannister.
As to the "slightly sepia brown wash" with greens coming out, my only
guess is that the operator did not adjust the color balance properly, or
you were shooting with tungsten lighting?  There really isn't enough
information to go on here.

What were you shooting?
Did you process the film yourself or take it to a one-hour place or
what?
Any other information that might be relevant?

my camera from CWoO, I asked them specifically about it and 
they told me that it comes with the camera automatically.

Unfortunately, a circuit breaker alone doesn't always do the job.  They
don't act instantaneously when the current surges.  There's a time delay
between the time a breaker "detects" a surge and cuts off the power.
This delay can cause the drive train to be seriously damaged before the
motor shuts off.

I worked as an engineer at a power plant where we had a large number of
conveyor belts protected by circuit breakers.  We still used to have a
machinist cut a groove in one of the shafts so it would break if the
load got too great.  Most of the time, the shaft would break before the
breaker would trip.

I'm not excusing Durst here.  IMHO, paper jams happen in print
processing machines, so they should be designed to handle them without
breaking.

Usually I would wait (till up to a month), but since I am leaving for

The order was put in exactly two weeks ago with a guy named John at B&H.
A Sigma 180/5.6 APO micro, at the advertised price.  I asked would it be

and they charged the amount to my credit card the day I ordered.

I have dealt with NYC shops before and most of them were disastors.  But after
seeing support for both B&H and Andorama in this group, I thought maybe
there are some that are all right.  So, if you have dealt with them

The topic of battery life of AF SLR using lithium has been discussed a
number of times in this newsgroup.  I am trying to find a point and
shoot camera for a friend.  I can easily distinguish the major
features of these cameras, but battery life is something that is
virtually impossible to figure out unless you own the camera.

Can anyone comment on the battery life of Point and Shoot cameras?  It
would seem that some of the bridge cameras with power zoom and a bit
more powerful flash unit may eat quite a bit of battery power from its
single lithium battery.

  I was browsing thru 'Vision: Human and Electronic' by A. Rose and came
  across the following:

  1 lumen of green light = 1.5 * 10^-3 watt
                         =   4 * 10^15 photons
  1 lumen of white light =   4 * 10^-3 watt    (dot over equal sign( approx?))
                         =       10^16 photons (dot over equal sign) 
  1 lumen/m^2 = 1 lux = 1 meter-candle (= is identical with) 
  1 lumen/ft^2 = 1 foot-candle = 10 lux (is identical, approx?)

  Well, that's more than you wanted, but maybe it will be useful.

This discussion of monopods and air travel reminds me of
an anecdote.  I few years ago I was travelling to the
Dominican Republic and a boisterous high-school baseball
team was on the flight.  They were being abnoxious (half-
loaded) and one of the guys was politely asked to surrender
the baseball bat from his carry on as this is considered
a dangerous weapon and should not have cleared the carry on
inspection anyway.  Well there I was sitting with my Cullman
monopod, a 16" metal rod with a good 2" diameter.  It seems
that this hunk of metal was not considered dangerous but
a wooden bat was.  Maybe I was just lucky.

As I understand it, circularly polarised light actually has a rotating
plane of polarisation. At any given point along the light 'beam' the
plane of polarisation will be in a different direction.

You're going to regret asking this! If you think of a light beam as
two coherent perpendicular components, you get circular polarisation
when the phase difference between the two is pi/2 radians.

A circular polariser is what is known as a 'quarter wave' filter. It
delays the phase of the transmitted light by a quarter of a wavelength
in one plane. (Don't ask me how, or what effect different wavelengths
have - it's been too long since I studied all this!)

I hesitate to try to run anything other than RA-4.  With all the warnings
about RA-4 chemistry being ruined by a little touch of this or that, I
decided to dedicate the machine to RA-4.  These days, I'm making no other
kinds of color prints.

I much prefer black and white in trays -- it is *so* much faster to do
six or eight at once in trays.  I also tend to vary the development
time a bit, and I like the freedom of seeing the print after a minute
in the fixer so I can get on with the next version.

	This is interesting. In the 6006, the increments are much smaller.
With my Sigma 28-70, the aperture settings as the lens zooms are

3.5-3.8-4-4.2-4.5

	This is at the widest aperture. If you stop down to say 5.6 then the
difference is 1 stop. I THINK the reason for this is that since the aperture
is set by the camera electronically, it can maintain the exact aperture
throughout it's zoom range by making the actual stopping down different. This
would not be possible in the widest aperture since it is already fully open.
Hence the user is not left guessing what the exact aperture is. This is just
my guess and if I am wrong please do correct me.

This is probably very true. For example, I doubt the Nikon
designers were setting out to make a "classic" in the series E
75-150, and yet it equals the 105/2.5 in resolution at that
focal length!!

Then again, I hope we can assume that for a particular, popular
focal length, Nikon will try, try again until they have something
excellent. Then again, maybe not. That's why I like to see the

I have the FM, which is mechanically almost identical to the FM2. I have not 
actually used a lens which required mirror lockup with it and neither the FM
nor FM2 have a mirror lockup function in the sense that it conventionally 
associated with mirror lockup. They do, however, allow the mirror to be held 
up, blocking the prism, when the self timer is set and the shutter is tripped. 
Basically, you set the timer, and trip the shutter. The mirror flips up,
blocking the prism, and the viewfinder, as the timer ticks away. Once the time
is up, the shutter opens. The mirror then returns to its normal position.

I don't think you can use lenses that REQUIRE mirror lockup with these cameras,
although I am now writing beyond my level of expertise. I ASSUME that these
lenses require the extra room in the camera body which is taken up by the
mirror. As a result, using lenses of this nature would not work well as you
would constantly have to trip the shutter and keep the self timer running. 

If you are only concerned with trying to minimize the camera shake associated 
with the mirror flipping up when doing very precise work, then this method may
work provided that the timer does not cause subtle vibrations.

I would be interested in hearing from anyone with a little more knowledge of
this.

I use a couple of different lenses on my CANON F1 for portraits, namely 
the 85mm, 1.8 and my 135mm 2.0.  To obtain the "soft" effect I use
the Tiffen SoftNet filters.  They come in several varying
"effects" of softness.  I also have a Hoya soft filter which I
don't like as well as the Tiffen only because to obtain the
best effect they recommend an f8 or higher (if my memory serves
me right), whereas the Tiffen filters obtain "softer" effects
by opening your lens up, e.g. f2.8 will give a softer look than
f8.  These filters are great for portraits.  I had one lady
re-order about 15 prints from one negative.  Her family and
friends thought it was the best picture they had seen of her! :)
Defousing will give a blurry picture as opposed to a picture that
is focused properly but with the "soft" effect.  Big difference.
For about 15-24 dollars, you will see for yourself.

I ordered a Nikon system from them that they swore was in stock.  The

"complete Tamrac line in stock."  To make a long story short, after
eight weeks I still hadn't gotten my complete order.  We had agreed on
a huge package (my old Minolta system had been stolen) and they
matched New York prices for many items.  What they then did was ship
only the high margin items and kept telling me that the stuff on which
they'd cut not such a great deal "wasn't in stock."

I shared many unpleasant conversations/FAXes with their customer
service manager.  On the whole, I would have to say that B&H and even
Adorama are vastly superior, especially if you remember to ask whether
the stuff is USA warranty or not.
