Check This Out- Fresnel Diffraction Applet
www.falstad.com/diffraction/
This link takes you to the site of one Paul Falstad to the applet for Fresnel Diffraction. If you select single slit, double slit, etc., you can see a visualization of the different apertures and optical effects. Its really helpful for me to see and be able to manipulate the parameters. I thought it would be interesting and educational to those who are dedicated to the art of pinhole photography. I encourage checking out the other applets that he has on his website, too.

Featured Pinhole Photographer- Paul Prober
Back in 2003, Lenox Laser hosted a Pinhole Competition. The submitted pictures were all stunning- beautiful and ethereal compositions of ordinary objects seen through the magical eye of a pinhole. You can view the photographs in the Pinhole Gallery of our Lenox Laser Wiki Knowledge Base.
I would now like to go back and revisit the photographers that contributed. So the first Featured Pinhole Photographer is Paul Prober.
He submitted two photographs to the competition- "Leaving Station" and "Courthouse Back Arch." Here again are the two photos:
I personally love the trees seen through the train on "Leaving Station." And "Courthouse Back Arch" is haunting in its beauty.
Paul Prober owns his own website, www.huecandela.com where he makes and sells other pinhole photography products. He and Bill Wellman also wrote a paper "Optimum Pinhole Camera Design." You can find it on the website or read it directly here.
What do you think of these photographs? Does it inspire you to try pinhole photography? It certainly inspires me! Let us know in the comments what you think, and also if you would be interested in participating in another Pinhole Competition in the (near?) future.
And, as always, check out our website www.lenoxlaser.com to see our pinhole products and to request more information. Check back here at the blog soon for more pinhole photography stuff and featured photographers!

NEW SERVICE PROVIDED BY LENOX LASER
In order to meet the high quality standards expected from our customers, Lenox Laser now offers a vacuum packing service to further ensure the integrity of manufactured parts from our facility to their intended destination.
Vacuum packing offers a wide range of advantages especially for those parts that require certain controlled conditions, such as, moisture-free or dust-free environments. Vacuum packing also reduces part movement in transit. Part movement or improperly packaged parts compromise a part’s integrity. This service may be of interest to our international customers whose parts must travel great distances.
Whether it is a single part or several, this vacuum packing service is highly recommended for our customers in the pharmaceutical, semiconductor and optical industries.
Call 1-800-49HOLES (4-6537) or email sales@lenoxlaser.com for more information. Be sure to visit our website at www.lenoxlaser.com to view our line of parts and services.

My First Encounter with Pinhole Photography
Being a new face at Lenox Laser, Inc of Glenarm, MD, I was fascinated by the world’s range of precision hole needs, but I did not quite understand all their applications. So I began my self education with PINHOLE PHOTOGRAPHY. I figured I had a passing acquaintance with photography, even if only of the “point and shoot” variety.
Boy, was I wrong.
First I discovered that PINHOLE PHOTOGRAPHY was invented centuries ago when man discovered that light passing through a tiny hole produced an image of the object on the surface it fell on. The earliest documentation of this discovery comes from the Chinese in the 5th century B.C., and was later expanded upon in the writings of Aristotle.
I found that the first published picture of a pinhole camera obscura was found in a drawing in 1545 by Gemma Frisius, an astronomer, who used the pinhole in his darkened room to study the solar eclipse of 1544. The term camera obscura describing a "dark room" was coined later by Johannes Kepler.
Then, Sir David Brewster a Scottish scientist was one of the first to make pinhole photographs in the 1850s. He was also the first to use the word "pinhole". The Nobel Prize winner, Lord Rayleigh, researched pinholes in the 1880s to achieve the optimal pinhole formulas still used by scientists today
So I learned that Pinhole Photography is unique in that it can require nothing elaborate or expensive in its simplest form and has been around for centuries. It needs no lens as normal photography does and can be made from cardboard or such with a hole in it. Like:

Light rays bounce off the image in a small and precise way through the hole and form a reverse image on a slip of paper or film. These cameras are usually handmade. Basically, the pinhole camera consists of a light tight box with a pinhole in one end, and a piece of film or photographic paper attached to the other end. A shutter devise can be a piece of paper or cardboard that can be folded out of the way as needed. The pinhole can be made by using a sewing needle or small nail through a piece of foil or the like. Remember, the more perfect the hole and the tinier the hole, the better the picture will be. This piece is then applied to the inside of the light tight box behind a hole cut through the box. An oatmeal box can be made into an excellent pinhole camera, but should be covered in foil to be light free. Sometimes Pinhole cameras are made with a movable film holder or back so that the space between the film and the pinhole can be adjusted, allowing the angle view of the camera to be changed. Moving the film closer to the pinhole can give you a wider angle view and a different picture.
So now I was more familiar with the Pinhole Concept, but putting it to practical use seemed to take some creativity and skill. Something I’m not so into. Did I mention, I was the “point and shoot” type? So maybe it only requires purchasing the proper equipment. Depending on how crafty you are and how professional and serious you are about the results.
At Lenox Laser, they make it easy for Pinhole Photographers to get laser-drilled pinhole quality (remember the tinier and the more perfect the hole, the better the picture) in a new line of practical SLR pinhole conversion products for standard 35mm cameras, a customer driven concept built by our R&D team.
Its’ simple, using the classic 35mm SLR camera format, Lenox Laser SLR Pinhole Kits can now easily outfit your Nikon, Olympus, Pentax, Canon, or Minolta camera with another lens in your arsenal, a pinhole designed for your specific camera. Lenox Laser online calculator’s page offers an array of pinhole calculators to aid your photographic efforts in finding correct exposure times, f-stops, and proper pinhole sizes. Currently, we offer PC, Mac, Palm, and Web-based pinhole calculators.
