Subject: Considering Canon EOS Elan - solicit comments

A salesperson showed me an EOS Elan this morning, and I left quite impressed.
The quick autofocus could be real handy for candids, and the pop flash would
work nice (?) for nature closeups in the woods/jungle.  Does anyone have any
opinions regarding this camera - likes, dislikes, suitable lens combos, etc.?

A quick thought, the lens she showed, a Canon 35-80mm F4-5.6 doesn't seem
to flexible - F5.6 is not much of a depth-of-field.  Is there better stuff
out there, or are most AF lenses limited in terms of small f-stops, and I'd
perhaps be better of sticking w/manual focus?

Thanks for all comments, Bruce Wilson

Hi, 
	I've stumbled across a box of Kodak 4x5 film, labeled:
"Kodak Safety Film
 Black and White
 Direct Duplicating
 ASA 0.5            "
followed by the usual warranty disclaimer.

It belonged to a member of the student darkroom here who graduated and left
some of his supplies behind for others to use.  It is probably two-three years
old.

Is this the stuff that lets you make negatives from negatives?  I took
a sheet out, it is on a thin base with a curl and looks like it has a yellow
almost translucent emulsion on one side.

I seem to remember reading somewhere that this stuff can be developed in
Dektol.  Is this right?  Anyone care to give developing times and some
hints?  I'd like to use this stuff to duplicate negatives for retouching,
creating special effects, etc.

				Thanks,

Some years ago (>10) I was lucky enough to get one of these brushes in a
large Toronto camera store.  I found it very effective and liked it very much.
Then it was borrowed permanently by someone at the photo club and I tried to 
replace it.  Well......  It seems the reason I got it at a good price was 
the store was clearing them out.  Canadian government regulations had changed 
making it impractical for them to be sold.  When I asked about mail ordering 
one from the states I was referred to the nuclear regulatory commission.
It was like I wanted to build a reactor in my backyard!!!  After drowning 
in red tape I gave up.  I have the Kostner brush now and it works OK but 
I still have fond memories of the old one.

At the time I did quite a bit of research and concluded that if you didn't
eat the thing you were probably quite safe.  The memories are faint but I 
think the isotope in question only really produces alpha particles that
don't penetrate the layer of dead skin that covers us all.

A recent article in the International Plastic Modelers' Society
Journal (v4n3) discussed using a pinhole lens (available from AJ
Fricko Co.  (513) 784-0019) for taking pictures of plastic models with
full scale prototypes and equipment in the backgroud.  Is there
anywhere that I can get more information on pinhole photography.  Most
of the books I've seen mention the pinhole lens while explaining the
operation of normal lenses.  The one or two books I've seen that go
into actually using a pinhole lens state that the sharpness suffers
when using a pinhole.  The pictures in the IPMS article are much
sharper than any of the pinhole pictures in the general photography
books.

I have seen brushes ect that have about a 7KV static eliminator. A cheap source
is an old line printer. The static charge that can collect on the paper basket
is awsome. I saw an operator go to remove the printouts from an output basket
that the grounding lead had come off. He bent over, grabbed the paper and let
out a scream and shot upright, rocking ~250lb og line printer with his head.
I heard the 'crack' of the dischage from 20' away, oer the noise of the computer,

I've heard of this contraption on the net a few times (Color Meter).  Is this a  
color analyzer or meter measures the distribution of light wavelengths.  If so,  
then what range does it analyze (UV -> IR)?

What are they used for?
How much are they?
Who sells them?
Are they portable?

It's possible to buy stick-on DX labels, so you can tell the camera what you 
like.  Good camera shops only, I expect.  A trawl through the last 2 years 
worth of any amateur photo mag will probably turn up a description of the 
coding scheme, so you could do it yourself.
If you only want to change the ISO value a couple of steps, does your camera 
have exposure compensation?  Letting it know the true ISO but making it 
underexpose by a stop would be the same as telling it the ISO value is 
doubled. (or would that be 2 stops?)

The slide is plastic, its the parts that mate the slide to the rest of the

that arn't (off the top of my head) are internal springs, the firing pin,
the barrel, the hammer, slide to gun interface, magazine to gun interface,

I have just purchased a Vivitar's Instant Slide Printer.  It allows me
to make color prints, B&W prints from 35mm mounted slides. It produces
3 1/4 x 4 1/4 prints from Polaroid pack film.
 
Has anyone else used this type of printer? I have tried it and slides
that are dark (night shots) so far are not coming out as nice as I
had thought they would.  Hopefuly with practice they will be better.
Does anyone have any ideas that would help me?
 
The film the printer takes is polaroid polacolor ER type 669 film or
polacolor 2 type 108 film for color prints.  the printer came with
2 packs of film, but can anyone tell me where I can get this type of
film?  So far I havent located anymore.Anyone know the cost?
 
The prints I made from slides that were normal exposures are coming out
great. I am making prints of slides I brought back with me from Greece.
This is my first time using a printer and this printer so far is very
simple to operate.
 
Any ideas, experiences, or suggestions on this printer or printing slides
would be appreciated.

Sigma, Tokina and Tamron are perhaps the most dependable 3rd party
lens makers.  But since Canon is out with its EOS series, it just might
be possible that the lenses for the AE-1 are now more affordable...
I own a 28-70 and a 75-300 zoom and they pretty much cover my needs.
If you want to stick to one lens, probably something from the wide to
medium tele, viz., 28 or 35 mm to say 70 or 80 or 105 mm would be good.
For portraits, focal lengths in the range of 90 mm to 135 mm are usually
in vogue (they give the right perspective!).  A polarizer is usually
a must for waterscapes etc.  Also a "graduated gray filter"might be a
good idea.  and of course a tripod would be advisable for say dusk(!)
or dawn or say when you wish to use f:22 or f:32 with an ISO 64 film.

>Also, does anyone post suggestions on how to improve on portrait and nature
>(outdoors - lakes etc) photography?  If someone can give me some useful hints
For portraits, I like to use multiple light sources (I have a small
2nd flash on a slave unit).  on the main flash I use a bouncer (you
can make one yourself with white cardboard or buy one; I use a Lumiquest
80/20).  In some cases a soft-focus filter looks good for portraits, in
some it doesn't - this is a matter of personal taste.  Also the s-f
filter works great with some nature shots, especially with harsh sun.
Order a filter catalog from a filter distributor (hoya,b+w, tiffen or
cokin) or pick one up from your friendly neighborhood store - they
would give you a rundown on a whole lot of filters - color compensation,
trick, etc. etc. you could add a rainbow to a perfectly sunny and dry
skyscape!

Another suggestion, nature photos usually look good when projected
or printed real big....  and so I like to use slide film.  And then
when I have the $ and inclination, I pick out the good ones and get
them printed poster-size.

Happy Photographing!!!

The radioactive material in the Staticmaster (I think it's a polonium
isotope) is an alpha-emitter. Alpha particles are strongly ionizing,
but they don't travel very far (a few inches in air) - as long as you
don't remove the grille and eat the strip, you won't get any exposure
at all. Since the alpha particles *are* so strongly ionizing, eating
the strip is a Very Bad Thing...don't do it, no matter how hungry you
are ;-). 

I used to use one of these when I was in high school (20 years ago).
There are other alternatives available now (in the darkroom,
I use a brush with conductive fibers grounded to a cold-water pipe).

Huh?  My EOS cameras (and I think this is normal for them) just open
up the aperture all the way, set the shutter speed to 30 seconds, and
then blink at you.  They'll still take the picture if you insist.
