In alt.binaries.pictures.misc I have posted a 4-part sample
of my first Photo_CD labeled "seward.jpg" (Seward harbor,
Alaska). It's taken from the highest resolution available
(3072x2048) and is clipped to panorama size: 2944x900.
Highly compressed with JPEG (Q=40), the result is still
reasonably good. You may be able to notice the grain.
Does it make sense to scan at 6Kx4K? For 100ASA film I
have my doubts...

The 4Base image (1536x1024) looks sharper and may be
posted at its full size if there is enough interest,
but the purpose of this post was to give you an impression
of what the new technologies offer at "reasonable" data
bandwidth. I hope you enjoy it!

Actually, in Av mode you set the aperture and the camera sets the shutter.
If, for instance, you set the aperture to 2.8, go out on a sunny day, and
pop up the flash, the viewfinder will blink 125 telling you that it's too
bright to use a flash. (i.e. the shutter speed may need to be 1000.)

Had he been using Tv or manual mode, then you would be correct(the shutter speed
would be sent down to 125 when the shutter release is pressed half way.)

Hi,

I have a Nikon N8008 (F801 in Europe) but this camera has not the spot
metering option (only N8008s). Does anybody knows if I can buy the
electronic pieces to allow my camera to use spot metering. If possible
how much would it cost and who could update my camera?
I'm living in France but I've planned to go in Oregon by the end of the

A'm having some problems with camera shake, and wonder if anyone has 
solved this type of problem.  I use a Bronica EC for medium format work,
often mounting it on either a Bogen 3036 or 3021 tripod with either a 
3047 pan/tilt head or a 3055 ball head.  The tripod is stable, and the 
heads solid, but the camera shakes so much that I get sharper negatives 
*handheld* at 1/250s than when mounted on the tripod!  

Experimenting a bit, I notice improvement if I hold the camera while on 
the pod, rather than use a cable release.  For very long exposures 
(>1/2sec), the problem disappears, as the vibration period is much 
shorter than the exposure time.  (The same tripod/hed combinations 
can be used with my 4x5s or 35mm equipment, with no problem.)

Has anybody had this sort of problem and solved it?  (BTW, the 
Bronica has no mirror lock-up.)

This depends on the resolution/beam spot size of the scanning device. Of
course, if you are using a desktop scanner which won't go higher than 300DPI,
there's not much you can do about it. But if you are using a more sophisticated
device (let's say something which can do 2000DPI scans), you might get into
trouble if you try to scan at a lower resolution, because it might not be
possible to defocus the beam enough to obtain an adequate averaging of the
area being sampled. In effect, the smaller the beam spot size with respect
to the width of a scan line, the closer you are getting to point sampling,
and the more likely you are to introduce aliasing artifacts in your scans.
The solution is then to scan at a higher resolution and to use a low-pass
filter to filter the samples and then downsample to the desired sampling
rate.

Kodak, Fugi et al market pre exposed films called 'control strips'. These are
processed and the measured on a densitomiter. They vary a bit by process but
generaly have patches to measure Dmin, Dmax, speed and contrast. Depending
on the process, there may also be other process specific measurements as well.
The Leuco-cyan on EP-2 is one example.

when you have measured the values, you log the results, and keep a plot on
graph paper of process parameters. This is called a control plot. It is great
for noting if your process has screwed up for some reason. If you are lucky,
you can see that the chemistry is heading for the weeds BEFORE you trash a neg
or slide. The process manuals have a section on faults, so you look up the
problem and follow a step by step fault finding procedure to determine what is
wrong and how to fix it.

The worst I have come across was a lab that cleaned out their processor with a
'copper' pot scourer!! A piece of the metal lodged in the filter of the
developer tank circuit, and contaminated the chem. ( The Agfa paper process
from memory ) This caused a green stain, and increased the magenta contrast.
It was NOT easy to sort this one out!! It also took several days to clear the
problem, as, as well as the bit in the filter, there where microscopic bits
of copper inbeded in the walls of the tanks... Not fun. But by running scrap
paper and control strips through the machine, I was able to be sure it was
properly cleaned out, BEFORE customer printing resumed, with the problems
that could result.

I'm not sure it really would have enough coverage for 6x9 except maybe
at macro ranges.  You need a lot less coverage to cover a format for closeups
than at infinity (I think a lens has an image circle twice the diameter at 
1:1 as at infinity).  I doubt that a lens designed for a relatively fixed
size and distance will cover more than necessary.

Hmm.. I'd have to put apeture & distortion along w/ cost & sharpness.

I have blown many a picture because my maximum apeture was not enough to
obtain a decent shutter speed, so hence a blurry picture.  There have been
times that I would have given an arm & a leg for an extra stop.
I have since bought a tripod but found that it's not always practical.

I got noticable distortion when I shot some pictures of the Golden Gate.  I
did my best to hide the len's distortion, but you can only do so much
with all of those vertical cables. :)

By mistake I posted the following in rec.photo, and I was politely pointed
out by many that the post should have been to rec.video, a group I didn't
know existed. Anyway, here is a question:

I am in the process of buying a Video Camera and I would like some help.
If there is a FAQ on this topic, could someone please mail me a copy?
Thanks.  If not, here are some questions I am interested in:

   1. What are most useful features to look for in a Video Camera (VC)?
      I can think of the following.
	 - Focal length: what is the best range of focal lengths?

	 - low light sensitivity: is a separate light source always required?

	 - microphone sensitivity: how far the subject can be for proper 
	                           sound pick-up?

	 - weight: what is the weight limit that makes it tiring to carry
 	           the VC/CC around for more than 10minutes?

	 - stability: for hand-held picture taking, which VC/CC provides the
	              best stability?

	 - 8mm or VHS?

	 - editing: should I look for any editing features?

	 - battery life: what should the expectation be on battery life?
			 how long would it take to recharge a battery pack?


   2. How is a Camcorder (CC) different from a VC?

   3. What is the best brand name for a VC/CC?
      In the features listed in 1. above, which brand is best in which set
      of features?

   4. I have a VHS/NTSC VCR, but my folks at home have a VHS/PAL VCR.
      Are there any VC/CC that can apply to both situations or should I be
      looking at a VCR that can play both NTSC and PAL coded tapes?

Thanks.

This newsgroup has seen a lot of discussion about U.S. mail order stores

>(and possibly U.S. screw sizes for tripods too)

Are you talking about cameras made in the U.S. by U.S. manufacturers or
cameras made in Japan by Japanese manufacturers but sold in the U.S.?
Japanese manufacturers do not convert products to BRITISH measurements
except maybe sometimes by special order.  Not cameras, cars, etc.
Though for some reason TV screens are measured in diagonal "inchi"....
Regardless, you probably notice a lot of focal lengths and film sizes
and other stuff in mm, no?

      Know what the price the equipment you are looking
  for .Ask alot of question and demanded to see anything
  the salesman promised. If he promised international 
  warranty then he should be able to show you etc.

      Some of the salesman are quite rude . If you don't
  feel like it walk out !!!. Don't be pressure into 
  buying. they are expert in making you buy.

      But of course you'll found a nice salesman. i forgot
  the shop i patronized but kept looking and know what
  you are looking for and its price in your country.

      Don't shy away from haggling the price.
 Ok that is for Hong Kong.
 For L.A i left it to others.
