Hello:
Anyone have a Packard shutter with minimum 3" opening they want to sell?
(Well, yes, it's a pinhole if you tried to fit your head thru it).
Thank you.
Murray
ould know better than me...I'm just spewing stuff I read
elsewhereI"m kind of spooked by most of the chemicals, but I have this
crude rule of thumb that if it's inorganic chemistry it's less evil than
organic chemistry as far as health goes (does not apply to organic fools
oops I mean foods :O)

black matboard, about 1/16" thick, poked a bent crooked sewing needle
thru it (it wasn't rusty) and sanded the 'blowout' on the back.
It might even be egg-shaped. Hey, I actually experimented without
calculating somethign to the 'nth degree'

Hey, this group is gettin' serious -
pinhole covert ops and industrial espionage
I'd suggest converting a Minox camera to pinhole but for the microfiche
reader needed to look at the pictures!

Laden pinata I saw on TV, but passersby might kick your camera.

That's cruel...describing your photos in such a manner! You must have a
marketing background you didn't mention, too!

pinhole shotsthe tail twitching
and contortions they do might be interesting with long exposures.

Thanks for the help, listfolks.
After reading some of the how/why debate...I'm going to see if the local
library can find RCO's pinhole thesis, so I can take a tangential (oops,
sorry, more techobabble) look at the artform from my own microscopic (or
would that be myopic?) approach.
Murray
r' approach.
Speaking of blind photographers, which has been discussed here earlier,
someone told me they met an artist recently who sold a painting to Stevie
Wonder...I paused for a moment, trying to imagine what or how he would
select, and she said that someone with him guided him and he selected one by
touching it. That was interesting, but that leaves us photographers out of
the loop.
Murray
for sharpness.
The description really got me interested - I was really curious exactly what
kind of 'little people' models you had...indeed dwarf is politically corerct

Ranamign the.dat's to .jpg's worked, but they were tiny thumbnails - needing
the proverbial tweezers and magnifying glass...or maybe a long f.l. pinhole
is more appropriate on this list. :O)
Murray
All but one page arrived with a .dat file extension.
Well, the simplest fiel conversion I could think of was to just rename them
as .jpg!
It worked!
I'm going to put them on my web page...

Hello:
Any idea why I always end up at http://www.???/discussion/
when I click on a hypertext link to someone's posted image, as in the

I then can't find the image, of course.

Hello:
I am practicing with a standard 4 x 5 film holder and the film I have is
thinner than normal.
I am having a great deal of trouble getting the film out of the holder
without kinking it.
I guess having fingernails might help...what do you folks do?
Thanks
Murray
searching I haven't turned up any.
Murray
I really like the mat board strip idea - if you use a piece with the bevel
cut, you could glue it upside down (as a 'reverse bevel' would look on
framed artwork), so the bevel would be raised to 'catch' the film/paper.
Murray
Thanks all replies - too lazy to reply individually
Murray
Has anyone ever tried making a 'ground glass' viewing plate (or whatever you
call it), either with 'non-glare' etched picture framing glass, or
subjecting a piece of this or other glass to additional abrasion?
Thanks

but if it's categorically toxic and needs specific disposal it would be nice
to know.

c or cubic diminution

a curved one like in an oatmeal cannister? Or what else would it be?
Thanks

Thanks for all the referrals to Van Dyke - Kallitype processes.

one ever seen a homebrew approach to a rollback of this size? (I
guess the full roll would need a tripod of it's own).
Thanks
Murray
As one of the ignorant new list members, I really appreciate all the help
from everyone.
It may take me a while to get to the point where I can be helpful, but if
anyone needs info on framing materials and techniques, I could help there.
Thanks
Murray
y film? If so, what kind of behavior does it exhibit with
light vs. x-rays (contrast?).
Thanks

f results and a slight variation in input
suddenly bumps the output to a new value...changing pinhole diameter from
0.26 to 0.27 mm shouldn't change optimal f.l. from 25.4 to 50.8 mm.
This what I used to come up with 0.25 mm for 38 mm f.l on my 35 mm
conversion maybe I need to go find my slide rule?

Hello:
What has made the cylindrical oatmeal vessel fall from favor? Is it the
translucent lid vs. the old opaque one that fully sealed the end?

There's no index.htm or default.htm, so you just click on each .jpg listing.
Some are emulsion transfers and some are image transfers. I labeled them all

Any recommendations for a cheap 120 camera that's pinhole convertable? Maybe
I should do that intermediary step before going to 4 x 5 sheet film.
Thanks

Hello:

I finally finished a 35 mm roll of color film in a pinhole-converted camera.
As I was warned, the clarity isn't too exciting.
I at least learned that I had NO reciprocity problems or color shifts.
Note I cut off the head of a l
I keep forgetting we're talking about short duration (film exposure, even at
pinhole-scale durations).

a minute there.

In general, fluorescent lamps should be considered a significant UV source.

Anyone know the actual URL for this site? I didn't find it with a web
search.

stop to take any shots.
I hope it's somewhere in range...I used a 250 micron (0.25 mm) hole. (bought
it commercially).

chance do I have of lucking out and getting accurate color as a pinhole

ing camera chamber), and shoot the same scene from the same
camera position, would just the field of view change, or would the image
size from the telephoto be 'closer' or larger than that of the wide angle
configuration?
Thanks for all replies
Murray
or double 10 x.
Ignoring other problems with exposure, no need to round off your odd f-stop
number corresponding to the size and distance of your pinhole.
I used f 16 because it gives me relatively long exposure result from light
meter to multiply.

ny use for other people, assuming
it works.
I CAN see thru the SLR viewfinder/prism a bit...not very well, but maybe
better than just guessing.
Thanks

Does anyone have reciprocity failure multipliers for common 35 mm films?
Kodak wouldn't address my question unless I gave them a specific product,
and I didn't know what to use yet. Fujii is mailing me datasheets, but who
knows how long that will take.
Thanks

Hello:
An engineer once told me 'twist' drills make a hole that is actually
slightly egg-shaped, but a reamer makes a round hole...reamers probably
don't com ein sizes that needles do, so needle is probably best (assuming
they are round!)
