If you have largely enough light to use 50 ASA, why use 3200 ASA ? 
Just because you don't want to change film ? Aren't the results likely to 
be very different ?

I use neither. For negatives, I used to use year-roll#-frame# but has
now switched to roll#-frame# with the year and lots of other useful
information kept in a separate (currently paper) file.

For slides, I use a simple sequential numbering system without roll#.
Sometimes, such as with 4x5" slides, there simply is no "roll" to
refer to. And when the slides are mounted, the association to a specific
roll is removed anyway, which isn't the case with negative strips.

This is, more or less what my slide mounts looks like (the * is a red dot):

   No, but I'm still waiting for Readyload Tri-X ...

Kodak promised Readyload TMX (TMAX 100) over a year ago but never
delivered... It is frustrating that Kodak cannot trouble themselves to
bring out their film in professional sizes whereas Fuji never seems to
have any trouble (Velvia hit the streets simultaneously in 35mm, 120,
4x5, 8x10, and 11x14).

	I'm currently trying to decide on a 4x5 Enlarger and I've

I'm afraid you have most likely already got one... :-I

Errata: for "data sheet" read "Instructions".

My apologies for the misleading title - I was just referring to the large
piece of paper included with each EF lens, but I didn't have it here when
I posted.  Anyhow, the sheet with "serial number" PUB.C-II-133W 1289S60

"When using the EF28-80 mm f/2.8-4L, shooting capacity will be
 half the value stated in camera's instruction book."

Now does anybody know whether this "limitation" also applies to any
other 'L' USM lenses, such as the EF300 f/2.8L or the "new" EF300 f/4L ?

Yes, it's really quite remarkable, isn't it?  Generally a very good group
of people.  I suspect that part of it is that there's a certain amount
of self-policing.  When someone starts posting in an abusive manner there
are usually several people who respond by pointing out that this is not
socially acceptable behavior.  Kind of nips it in the bud.   Gee, just
think what our society and world could be like if the principle could
be adapted outside of rec.photo.  'Course it's much safer, physically, to
object to someone's behavior in an electronic posting than to object to
someone robbing a bank while it's happening! ;-)

I am starting a home darkroom for processing only 35mm B&W.  I am going to
mail order the enlarger since it is the largest cost with the greatest
potential savings.  The following is a list of inexpensive models that I have
seen often:

  * Besseler Cadet II w/ 50mm lens -- $105
  * Besseler Printmaker 35 -- $140
    + Needs 50mm lens kit (I think) -- $80
  * Omega C700 -- $130
    + Needs 50mm lens kit (I think) -- $55
  * Saunders Dual 35 (lens?) -- $140

Does anyone have any experience (good and bad) about these, or know of any
other inexpensive models?

   Hello all, I have a few questions for the group here...
I was heavy into darkroom work. Color neg film (c41) and ektaprint
color prints, as well as tri-x and B&W printing. At that time I purchased
chemicals from Zone V inc, Brookline Mass. I don't think they are still in
bussiness. Does any one know where I can get c41 & ektaprint
chemicals in bulk (6 qts) cheaper than Kodak? I've seen an add for
Photographers formulary, but they listed all B&W chems, do they carry color as 
well.

   Next question. I have 5lb containers of dry powder chems of almost 
every chem a darkroom would need. What is the life expectance of these.
I figure it some of the color chems would loose strength faster than
others. They have been sitting around for 7 years now. That was when I decided 
to remodel my darkroom and shut down the pumbing system.
   Also, what is the disposal procedure for various chemicals.
Thanks, Sorry if these questions have been hashed to death before, but I
haven't had time to follow the echo.

Hi.  If I am not wrong, Leica M6 is a fully mechanical shuttle camera with
TTL metering...

However, I think the more important point is that TTL sensors oftern draws
its power from the camera batteries.  If the camera batteries are dead, one
would not be able to use TTL flash with the mechanical shuttle even if
the flash is fully charged.

I think that the camera power options employed currently are absolutely
stupid, especially those Lithium cells (button or other wise...), a camera
battery pack using normal AA batteries would, in my opinion, be much 
better.

Good Health.

There's digital photography - acameras that dactually igitize and store images on 
floppy or hard disk - NO FILM - also camera backs for Nikon that do same.  I think some
manufacturers dabbled with or have 'consumer' level models, but for the most
part, those out there worth anything are geared to the wealthy and the pros,
with the Nikon back going for about 15,000...

Then there's digitized photographs - slides and prints ( and movie frames ) scanned
with a digitizing scanner... 

News groups under alt.binaries.pictures deal in the latter.  There are several groups, 
specifically a.b.p.erotica, a.b.p.fine-art, a.b.p.fractals, a.b.p.misc, a.b.p.utilities,
and a.b.p.tasteless.  In all of the groups except utilities, posts are (uuencoded) digitized
photos in one of several formats: usually GIF or JPEG (JPG).  Each picture group also has a
subgroup 'd' for discussion of pictures in the group.  The utilities group was created to 
share info on the various formats and to exchange code related to digitized photos.

Look there and see what you find.   Unfortunately, the a.b.p group is not always carried
by all sites because of the nature of postings in 'erotica', and also due to the disk space
required for all of the (large) posts.  Also, I find that rec.photo is almost an exception to
the news groups, in that almost all of the posts in this group adhere to the 'rules', there is
little or no flaming, little redundant posting, and generally quality questions and responses --
I have learned alot reading this group  (Thanks to all of you).

alt.binaries.pictures attracts more flamers, rule breakers, people who take a posting, and
repost it with their addition at the bottom ==> 'Me Too!'.  So expect to wade through alot
of garbage to get info on what you want.

Good Luck

I hope you meant "....more than 1/1000 sec...." and not LESS. In anycase
usually reciprocity failure on the high speed end is in the 1/4000 sec
or maybe the 1/2000 range.

It probably would be able to if it knew about a particular films reciprocity
problems. It might help if such info were in the DX encoding of a film.

I use Don Graetz Studio, 22 Prince. They are very good but not cheap.

I could not guess why it is less expensive than normal slide film.  It is,
however, different; it has much lower contrast and is not balanced for
daylight.  The lower contrast is important in keeping the overall contrast
of the duplicate under control.  And yes, it is very slow.  Exposures
using a dichroic enlarger head are a few seconds.  I've used Kodak
Ektachrome Slide Dup film 5071 and it does a nice job.
