Zero Image 2000
Carlee Members
One day back in 2011, I was walking along the shore at Rockaway Beach, New York, capturing scenes with a Fuji S3 Pro digital camera. I noticed an area of beach sand with about a 45 cm drop-off due to tidal erosion.
I send out my film for processing and scan the negatives using an Epson Perfection 500 flatbed. Then I use Photoshop CS4 to correct for exposure (thank goodness for the latitude of film) and I might add some contrast. There is also some manual dust removal done.
There are several groups on Flickr dedicated to pinhole photography. You will find some amazing work out there to view and perhaps stimulate your GAS. You can view the album along with my other photos here. Hamish has also shared some images taken with a Zero 2000 here.
I think I have largely corrected the main problems with my Zero Image 2000 pinhole camera which I documented in a post (link) a couple of days ago. I blackened the brass fitting that holds the pinhole, both inside and outside, with a felt pen. The surface is still shiny and this may explain on some photos a strange arc of flare in the upper left. I suspect blackening the brass is what eliminated the circular flare I was getting before. Eventually it would be worth applying a flat black paint to the brass fitting.
I also attached felt to the underside of the shutter, and that is most likely what eliminated the horizontal beaded flare which probably was light leaking under the shutter. There is still flare when shooting into the sun, but it is mostly the kind of flare common to pinhole cameras and thus expected and acceptable.
The only bit not working well enough for my liking is the shutter which, though it slides much more smoothly, still does not open smoothly and sometimes sticks partly open, or opens in stages leaving vertical banding where the right side has a shorter exposure. I put some slippery baking paper underneath the brass plate on top of the shutter and that helped it slide more smoothly, but the problem persists. I will have to get some proper low-friction tape for this surface. Making sure the shutter is open results in a lot of unnecessary camera motion and blurring of the image.
I see why Zero Image developed a shutter that can be fired with a cable release. If it was not so pricey, I would buy and install one. I guess I will have to experiment with some other solutions. For instance, if I pull the shutter from exactly in the centre of the ridge designed for that purpose, then it slides much more reliably than if I am a touch off centre- perhaps it needs a notch of knob so I can feel the centre.
Thanks Andy! Sometimes a camera proves quite tiresome. But, I have learned a great deal about the fundamentals of photography from some of them so it has not wasted much time. And, there is a lot of satisfaction in getting a decent image out of a problematic camera.
These pictures were all captured with my Zero Image 2000 66 pinhole camera on Kodak Portra 400 film. This setup is currently competing with my other favorite, a 3d-printed Flyer 66 pinhole camera loaded with Ektar 100.
Both cameras captured almost all of the images in my pinhole seascapes book, Vues sur mer. In the book, I use a number of series of four images, each series taken with the same camera on the same roll, to emphasize tiny color gradation and subtle cloud formation movement. The progression of the images throughout the book simulates the passing of a single summer day from morning to dusk. The present selection includes more recent pinhole seascapes from the same locations.
The Zero Image 2000 is so small and lightweight that it usually comes in my bag wherever I go, and since all paths seem to lead me eventually to two favorite hounds, namely the promenade near the old Yafo harbor and the new Tel-Aviv harbor, that is where it will perform its magic, in daytime or more often at dusk, on a gorillapod or, most often, just perched on a rolled up sweater on rock or ramp. With Portra film and its very forgiving exposure latitude I hardly have to meter the exposures any more, which is part of the pleasure in using it with a pinhole camera.

It looks far too good to be anywhere other than behind glass in a cabinet. The Zero 2000 66 (120) roll film camera has an equivalent 35mm focal length of 25mm and is capable of producing stunning images but forget about sharpness. Pinhole photography is all about atmosphere!
Zero Image 2000 Basic Back to Nature Pinhole Camera with Cable Release uses 120 roll film and produces 66 format images. The cameras are made of solid brass and high-quality teak wood, with a hard wax-oil finish.
Every Zero Image pinhole camera has a serial number etched on a beautiful brass plate. This can be found inside the camera. As well as a signed certificate of authenticity in each box. In addition, you will find step-by-step instructions, complete with illustrations, on how to use the camera.
Zero Image have made hand-made wooden pinhole camera in Hong Kong since 1999. The company founder Zernike Au is a pinhole enthusiast. Before he made his first Zero Image camera, Au was a successful product designer.
The art of pinhole photography and the beauty of antique wooden cameras fascinated Au. So, he made a decision to make a compact wooden pinhole camera which could accept roll film (at that time 45 was the only format available on the market). He also wanted his camera to have all the necessary functions and be easy to use. To do this, he began from Zer0.
Off-axis holograms recorded with a CCD camera are numericallyreconstructed with a calculation of scalar diffraction in the Fresnelapproximation. We show that the zero order of diffraction and thetwin image can be digitally eliminated by means of filtering theirassociated spatial frequencies in the computed Fourier transform of thehologram. We show that this operation enhances the contrast of thereconstructed images and reduces the noise produced by parasiticreflections reaching the hologram plane with an incidence angle otherthan that of the object wave.

I am observing an unusual behavior. I have a floating dialogue box in which I am placing an image. I want to get the image size using jquery and resize its div container to the appropriate size. It works fairly well, but the function occasionally returns zeros as the image sizes.
You can bind a load event handler to the element before adding it to the DOM, to get the width/height once it's available. You can also explicitely set the width/height of the image using CSS or inline attributes.
I like to bind the load event handler to the element before adding it to the DOM or changing it's source, this way you know the load event is in place when the image actually loads (which can happen quickly from cache).
I had this problem trying to get the height of a containing paragraphs and it wasn't because the content hadn't loaded - I tried alerting the height of it on a click so I could be sure it was there 1st and was still getting 0 returned. It turned out to be a css issue I added a clear class to it using the clear hack:
Old partition tables, LVM metadata, raid metadata etc can cause problems when reusing a drive. Zeroing out sections at the start and end of the drive will generally avoid these problems while being much faster than zeroing out the whole drive.
Those commands will overwrite your sda device with zeroes -- the first one will do the first 16MB (block size of 4096 and count of 4096 blocks) and the 2nd one will overwrite the last 2MB (512 block size with 4096 blocks) with zeroes. (it's not technically erasing, and that relates to my first point below.)
Another thing that is worth mentioning is that the block size does have effects, but those are generally only seen on high-volume operations. The most efficient (fastest) way to execute the command is if the block size of the command matches the access size of the device, otherwise time is wasted.
WARNING: dd if=/dev/zero of=/dev/ is used to clean a drive or device before forensically copying data. The drive or device must always be sanitized before copying information from a system under forensic investigation to mitigate cross contamination. Therefore, it is not a bad command, the end-user must understand what it is used for or they will destroy their data. If this is what you desire then to verify the zero write operation do dd if=/dev/sda hexdump -C head.
The point in dd having seperate bs and count argument is that bs controls how much is written at a time. Specifying really large values for bs will require a really large buffer in the program, and specifying values less than the block size of the device will be slow because the kernel has to build an entire block to write to the device (in cases like this it can probably buffer the writes until there a complete block, in other cases it might have to read what's already on the disc). As the two commands use different values for bs, that leads me to think that you might have found them on two different sites. Hard discs used to have a block size of 512 bytes, corresponding to the bs=512 of the latter command, but some (6-8 I think) years ago they started making discs with a block size of 4096 bytes, making bs=4096 a better choice for modern discs.
