[pinhole-discussion] Digital pinhole

Thought y'all might be interested.  There is an article in the latest issue
of PDN on digital pinholes.  About Arnold and David Katz work with them.

Here is another interpretation of digital pinhole. I made this image using a
tiny hole in a cracker served at the artist's reception for a digital
photography show I'm in. Had to keep my priorities straight.

[pinhole-discussion] digital pinhole?

[Fox, Robert]

Good discussion on this topic.

Has anyone tried to convert a digital camera to pinhole?  I'm guessing that
the results would be poor since digital ccds do not handle long exposures
well at all, resulting in a lot of digital "noise" and artifacts. But who
knows, it might look interesting..

I would enjoy tearing open a few of those consumer digital cameras though
and installing a pinhole!  Surely someone out there has already done this??

Here is an image from a pinhole bodycap on a Nikon D1X digital camera.
www://???/discussion/upload/gallery2002.php?pic=digital_pinho
le.jpg
The camera allows exposure times up to 30 seconds. Compose and meter for F22
(you can pre-set ISO and just use what you were otherwise using). Multiply
exposure time at F22 by 40, take the lens off, put on pinhole, change mode
setting to manual, set the calulated exposure time and shoot. Other than the
stunt of doing digital pinhole, it's kind of a nothing experience. Because
the CCP is smaller than a 35mm negative, you compound the effective focal
length by 50%, in effect you are shooting with a 75mm lens on 35 mm format.
On the other hand the D1X is an absolutely wonderful tool.

Is it possible to make a pinhole photo using a digital camera?

[pinhole-discussion] Digital pinhole images

[Dieter Bublitz]

A friend tried a pinhole bodycap with his Canon D60. The images can be
found at:

http://www.die-ritters.de/pinholeexperimente

While the results are better than expected, we noticed some funny dots
on the pictures. An example can be seen at

http://www.die-ritters.de/pinholeexperimente/punkte.jpg

Does someone have an idea, what these dots are? Internal reflections
on the chip?

Ed, you might try the MACO 820IR film. It's sensitive to higher nanometers
than
the other spiked red films. It also comes in 120 and 4x5. I recently shot
some in my Fuji 6x9, using an 87 IR filter. Long exposures, but very nice.
And the film is pretty fine-grained in Rodinal. I haven't yet used any in my
4x5, but intend to very soon. I use a pinhole in a recessed lensboard, set
for about 50mm. I think the MACO is going to do very nicely, even if it
isn't HIE.

Because most digital cameras are CCD, they have little lenses over the
tops of each of the sensors, so are they authentically pinhole cameras?
Guess it's a matter of theology.

I've routinely shot several second exposures with digital cameras (not
pinhole) without horrible noise problems, and you can remove a lot of
noise in photoshop anyhow.  Many of the infrared camera experiments in
the digital world (you have to remove the infrared filter glass that
sits on top of the CCD, replace it with other clear glass of exactly the
same thickness) are many-second exposures.

I've been craving pinhole with infrared imaging capability, difficult
with Kodak now only producing 35mm infrared film.  Perhaps pinhole
digital is the way to go.

Pinhole infrared is easy with a 35mm pinhole camera, red filter and Kodak
high spees IR film. See my page from the '99 pinhole swap:

Wow, I didn't know aboiut any of this specialized digital equipment --
thanks for the information! I'm still not going out to buy a new digital
camera, but I will consider some older models that are now getting dirt
cheap, especially used.

hi,

CCDs have a property of reading heat as much as reading light, since 
heat has also its waveform.

long exposures makes the CCD surface get moisty, I believe that this is 
why we get those dots, they are from the heat interference.

so, you need a CCD made for long exposures which is called cooled CCDs.

they may be found in cameras used for astronomy (pinholes whatching the 
stars).

I suggest you take a look at this animation of a comet made with a CCD:

Most astronamers use digital now. So digital can do long exposures. It's
just that most digital camera aren't designed to.
I imagine that it takes a constant stream of photos, and merges them
together.

Re: [pinhole-discussion] digital pinhole?

[erickson]

I used a pinhole bodycap on my nikon D1X. You can calibrate the exposures by
just looking at the LCD and trying again. All in all I didn't like the
process or the results. It seemed like too much horsing around with
machinery, and the acceptance angle is pretty narrow.

that property explains why we have so many CCD cameras with night shot

"monkeying around with equipment", as William EricKson said, may violate 
the orthodox pinholing life but, IMHO, excluding the digital world from 
imaging and pinhole photography is to live in a cave without coming out 
to enjoy the trees (although looking from inside of a cave is the 
fundamental pinhole experience).

btw. I tried the scan experience but it will only work with a 
transparency adapter so the software may be fooled and will turn the 
scanner's light off and read the projected light from the pinhole.

I've built one digital pinhole out of a broken sony s70 by taking out 
the lenses (its not a removable model so I had to unscrew it) and 
placing a matchbox inside with metal paper pinholed.
since the pinhole is so close to the CCD (a beautiful piece of blue 
cristal)  the images I get are something like a 50mm or less, without 
distortion because the CCD is flat.
I couldn't manage to record any pictures because the camera didn't 
'understand' what was going on but the video out plug kept working fine 
so I could see my images on tv.

I am told that it is possible to use a camera body cap with a pinhole in on a 
Canon camera. Set the dial to aperture priority which, without a lens fitted, 
automatically selects 'stop down metering' and will give the correct exposure 
for the film speed set.
The pinhole is approximately 0.28 mm dia.

[pinhole-discussion] digital pinhole cameras

[Jeff Dilcher]

I think most pinholer's use pinhole cameras for the romantic / nostalgia
reasons- kind of a way of getting back to basics, and thumbing one's
photographic nose at "technology".

Hey, why not forget pinhole, and just take your digital camera picture,
and apply some kind of "pinhole filter" to your file in Photoshop?  Seems
much easier method of achieving the end, than retrofitting some kind of
digital back to a slow pinhole camera.

I would be willing to bet you are probably not into pinhole for the nostalgia
reasons listed above, so it might be best to bag the pinhole altogether...

[pinhole-discussion] digital pinhole cameras

[Bretton]

Hi,

I know there has been some discussion of digital
pinhole cameras on the list, but not much...

Does anyone know if the cameras marketed for
surveillance purposes are very high res?  I would
assume not, but I couldn't find any ads that mentioned
resolution.

I want to buy/make a digital pinhole camera that will
produce nice looking digital prints (8x10 or 11x14)
without showing pixels.

Anyone have any suggestions, ideas, or plans for
building your own digital camera?

I use a 4x5 pinhole camera now, but find it a bit
tedious and time consuming to deal with sheet film and
developing, etc...I guess I could get a digital back,
but i assume that's an expensive option.

Thanks!

This may not be the kind of digital image you are interested in, but I have 3 
pinhole images made with a Barbie digital camera at:

Looks like dust or dirt on the sensor.  Most are in the same place in
every image, and some images have more than others (the dust
accumulated...)

A friend tried a pinhole bodycap with his Canon D60. The images can be
found at:

http://www.die-ritters.de/pinholeexperimente

While the results are better than expected, we noticed some funny dots
on the pictures. An example can be seen at

http://www.die-ritters.de/pinholeexperimente/punkte.jpg

Does someone have an idea, what these dots are? Internal reflections
on the chip?

Dieter

Hi:

You could try converting a scanner into a camera.  A scanner is essentially a 
very specialized strip 
camera designed to take panoramic pictures of pages.

You could try getting a cheap or broken one disabling the light source.

Info on making a lens based scanner camera is at

Re: [pinhole-discussion] digital pinhole cameras

[Mike Vande Bunt]

First off, the "pinhole" video cameras are actually lens
cameras with a pinhole in front of the lens to male it more
concealable.  


Second, NO video camera is capable of producing
nice looking digital prints at 8x10 ot 11x14.  The resolution
just isn't there.  To make matters worse, "pinhole" security
cameras are usually low resolution even for video.

A 4x5 digital back is a VERY expensive option.  But how
about a polaroid back?  If you're going to scan the image
and make digital prints you can avoid the hassles of storing
and clearing the negatives (see the ongoing discussion in the
list...) and have a choice of color and b&w films in a wide
range of film speeds (100 to 3000).

I want to buy/make a digital pinhole camera that will
produce nice looking digital prints (8x10 or 11x14)
without showing pixels.

Anyone have any suggestions, ideas, or plans for
building your own digital camera?

I use a 4x5 pinhole camera now, but find it a bit
tedious and time consuming to deal with sheet film and
developing, etc...I guess I could get a digital back,
but i assume that's an expensive option.

Hey!  The ancients meet the moderns!  ...-:))

Some time ago, I gave a pinhole workshop and one of the participant was using
a 35mm Nikon digital camera with a pinhole on the bodycap.  This is the
easiest, if you happen to have a digital camera with interchangeable lenses
or if you can have access to one.

He had some interesting results, but if my memory is correct,  there was a
fair amount of "noise" on the images due to the low levels of light hitting
the "digital emulsion".  He had posted some images on the web, but I seem to
have lost the URL.

I played around with a Barbie digital camera a couple of years ago as an 
inexpensive way to experiment.  I found my posting and a number of others 
relating to digital pinhole in the archives:

[pinhole-discussion] digital pinhole camera idea (what!?)

[Trent Dowler]

Hello All,

 While walking through the local outlets, I've come across the one
time use digital cameras that are now making their way onto the market.
My first thought was, "Hmm, I wonder if I could pinhole that thing?"
 Knowing so little about digital cameras, I ask the list...
 Has anyone else thought about this? Is it possible? Should I
attempt to build one of our beloved pinhole cameras using this "latest
technology"? Is this blasphemous? Will I be ostracized from the pinhole
crowd for toying around with it? 
 If it's possible, it sort of looks fun. At least, it's a new twist
on things.
 I'm looking forward to hearing from the group.

Later,
Trent

Hi,

It is my understanding that these surveillance cameras have TV resolution
(330 pixels tall) so this will only be good for about a 1x1 or 2x2 print.

I also shoot digital (Sony 707) and am happy with the 8x10 and mostly happy
with the 11x14.  This camera has 5M pixels so you would probably need 
approximately
5-6MP.  The consumer level cameras in the size range are $700-1100 but have
fixed lenses and I don't see any way of converting to pinhole.  The alternative
would be to get a digital SLR (Nikon, Cannon, Sigma, or Kodak) and use a
pinhole body cap in place of the lens.  Anyone on the list done this?  One
issue for digital cameras is that the image is noisy after the shutter is
open for a second or two.  The 707 has special noise reduction that allows
clean 30 second exposures (good for night photography), I don't know about
the digital SLRS but that would be a consideration.

Friends say that the best 4x5 digital back is BetterLight and cost $10-15k,
however these backs are all scanning so there is a limited range of exposure
times (betterlight goes down to 1/8 second).
