   Dear rec.photo:
   This is my first post to this newsgroup, so please forgive
   me if this topic has been hashed-over before. The question is
   this:  instead of plopping down $500 for Kodak's combination
   CD/Photo-CD player along with Photo-CD development charges,
   is there software available so that persons with a IBM-clone
   PC can read a Kodak Photo-CD if they have a CD-ROM player
   hooked to the computer already?
   1.) If so, what is the name(s) of the available software.
   2.) If no, is there software planned for the future to do this,
       or has Kodak set the Photo-CD standard somehow that only
       commercially-produced Photo-CD players will be able to read
       the discs?
   Any responses should ideally be sent to my e-mail address unless

The source code to a program for reading Photo CDs where posted only a few
days ago in alt.sources. I think it is written for SUNs, but I doubt it

No, I don't find it uncomfortable. The bag I use is not very big, so
it doesn't interfere with my movements. I think it is the safest place
to carry a camera, since it is the easiest part of your body to
protect in a fall.

Organization: Netcom - Online Communication Services  (408 241-9760 guest) 
Date: Wed, 16 Dec 1992 08:17:26 GMT

I have the SB21 B macro flash and have a question concerning its
use.

The manual isn't quite specific enough when discussing 
the F stop settings and in which modes those settings 
can be changed.  I have a Nikon 8008s and I am assuming
that I change the camera's auto mode to Aperature priority,
select the desired F stop on the lens, set the flash to TTL mode
and shoot the picture.  
Am I correct? I have been shooting shots in the 
"P" programmed mode but all shots are shot at F 4.
Prior to wasting more film on testing this out,
I thought that I would ask.


Thanks for your help!

You may be interested in the following information taken from a 
White Lightning Ultra brochure.  Note that, since a joule is a watt-second,
the following chart shows Paul is correct.  The actual watt-seconds of the 
three Ultra units are half their model numbers.  If you are interested in
power load, all three units are rated at 12VAC, 50-60Hz, 6A.  If you are 
interested in light output, check out the on-axis output below.

For the three units they state that actual output compares to other
popular systems rated from 900Ws to 2700Ws (U1800), 600 to 1800 Ws (U1200),
and 300Ws to 900Ws (U600).

I don't have any of these units but they sure look interesting.

Did you try playing with the flash exposure compensation control?  That

Try getting a 430EZ.  It's got more reach, and runs off AA's.  It too has
flash exposure compensation if you want to adjust the balance between
flash and ambient light.

I do black-and-white photography under tungsten light all the time.
No problem.  Color correction is not an issue.

Theoretically, if you use plain tungsten light, reds and yellows are
rendered slightly lighter than if you use light equivalent to
daylight.

(On the other hand, there are lots of people who feel reds and yellows
*ought* to be rendered slightly lighter than b&w film normally does,
and who use yellow filters when shooting black and white outdoors.  So
there.)

   Yeah, but I wouldn't trust it.  Not all flashes can live up to their
   rated guide numbers when new.  An old one might be much worse.  It is 
   easy to check - take the flash and a tape measure (no need for a camera)
   someplace where you can borrow a decent flash meter - camera store,
   photographer friend, photo dept. at school, etc.  Have someone hold the
   flash at the end of the tape.  Pull out ten feet or five meters of the
   tape measure and put the flash meter at that spot.  Make sure the flash
   is all the way charged up and fire it into the flash meter from the
   measured distance.  Read the f-stop from the meter and multiply it by the
   distance you've measured.  Voila!  An accurate guide number which you can
   actually use to make correct exposures.  (Might be good to fire it more 
   than once and average the numbers.)

   My neighbor came over just the other night to show me his new flash.  I 
   had loaned him a Vivitar 283 and he decided he wanted a good flash.  He
   had gone to the local shopping mall camera store and they talked him into
   getting a store-brand flash.  It was rated the same as the Vivitar, was
   much lighter (true!) and half the price.  I measured the guide number as
   described above and we measured twice the light output from the Vivitar.
   He took the new flash back the other day and mail-ordered a 283 for the
   same price as he paid for the crummy one.

   I guess I have repaid him for looking after my house while I am gone.

According to a salesman I talked to a few months back, the TC-16A only

Hi!
Back some time ago, there was a periodic monthly posting from Douglas
Blondin that consisted of a constantly-updated survey of the entire
field of mail-order photographic, video, anmd small-electronics
mail-order sources. The latest one of these I've seen was dated November '91.

I used to get it on the Videotech mailing list, which was gatewayed
with rec.video. When it stopped appearing there, I sent in some e-mail
inquiries, but never saw any responses. I didn't know if Mr. Blondin
had lost his net access, if the posting was discontinued, or if it had
continued, but had gotten too big for the Videotech digestification software
to accept as input.

My USENET access is limited to this guest account, so I did not pursue
the issue, but I am trying to check on it now. I just scanned through
all of rec.photo on this system for the string "mail", finding various-case
versions, but not this 
specific monthly posting. I'd appreciate it if someone familiar with the
what I'm discussing could drop me an e-mail and let me know if this
survey still exists, or if it has moved top some other venue, or if it really has been
gone for the past year.

Thanks!

I've made one and I can tell you why. A NiCad pack the size of a 2CR5 has
the capacity to shoot maybe a couple of rolls of film. Nothing beats the
energy density of Li cells. Now there are rechargable Li cells. You can
buy them today, but only in "button" type cells. They are working on 
bigger units and some may be seen in 1993. Rechargable Li cells may have
2.5 times the lifetime of NiCads (2.5 times more charging cycles). The bad
news (of course) is that they may be considerably more expensive than
primary Li cells (but much cheaper to operate). Lithium cells give you the
maxiumum energy density, so they are small, light and powerful. You pay for
those features in the price (whether you want to or not in the case of EOS
users like me!). There is a short article on battery technology in the
December issue of "Electronic Products" magazine (a trade mag.) which might
be of interest if you have access to it.

I just checked it again and you're right. When I wrote my previous
